1.2 EXPLORATION STATUS

The area was identified by CMPDI for scout drilling in March 1989 on the

basis of some boreholes drilled close to some of the GSI boreholes,

namely, SM-4, 6&8 etc. in the eastern part of the Amadand tract and


JOB NO.-515126 ES / 3 of 39

DGM (MP) was entrusted for scout drilling. The results of the scout

drilling conducted by DGM (MP) revealed presence of good quality

workable coal deposit in an area of about 60 sq.km of the intervening

Amadand tract between the working mines of SECL.

Detailed exploration of the area was taken up by CMPDI in August 1990

and comprehensive geological information was provided in Geological

reports on Bartarai Block in December 1993, Amadand Opencast area in

December 1995, Bakulmuni Block in July 1997, Amadand East U/G Block

in January 1998 and Amadand West U/G Block in November 1999. The

block measures 15.061 sq.km. which includes 14.154 sq.km. free area

and 0.907 sq.km. forest area.

The borehole density within the block is 15.20 BH / sq km.

1.4 JUSTIFICATION OF PREPARATION OF RPR

Amadand OC (1.15 Mty) was prepared with an average stripping ratio of

4.58 cum/t considering only upper seam i.e UK. Later on, decisions were

taken to extract coal from bottom seams upto bottom most LK-II seam.

Accordingly, this report is formulated considering all the seams upto bottom

most LK-II seam for mining with outsourcing option.

Liberalisation of power sector by Government of India has generated

wide spread interests for private and public sector investments in power

generation and other industrial development. As such, there is an

appreciable increase in the number of upcoming new projects in both

private and public sectors. The demand projection from SECL for the

The PR has been formulated to win coal by Surface Miner with FEL and

trucks/dumpers & OB by Shovel Dumper combination. Transport of coal from

face to railway siding will be done by inpit belt conveyor & surface belt

conveyor.


JOB NO.-515126 ES / 6 of 39

Both winning of coal and extraction of OBR will be done through outsourced

HEMM. PR is giving IRR 13.55% at 85% level of production. The overall grade

of coal is “grade G-8” with GCV 4933 Kcal/Kg, which is easily marketable. As

per the guidelines, a Project is economically viable when it achieves more than

12% IRR at 85% level of Production. Since, this Project is having Internal Rate

of Return more than 12% at 85% level of target production i.e. 13.55% and

hence Outsourcing Option of this project is economically viable project.

The outsourcing option of RPR for Amadand Opencast Project (4.00Mty)

was placed before SECL Board’s 236th meeting held at Raipur on dated

04.09.2015 for a total capital of Rs 869.44 Crores and SECL Board directed to

submit the same to CIL, since capital provision in the RPR exceeds Rs 500

Crores.

Accordingly, RPR for Amadand Opencast Project (4.00Mty) was placed

before 325th CIL Board meeting held at Kolkata on dated 05.03.2016 for a total

capital of Rs 869.44 Crores. CIL Board accorded its approval to Project Report

for Amadand Opencast Project for a rated capacity of 4.00 Mty at an estimated

capital investment of Rs 869.44 Crores for implementation of the project with

total outsourcing variant i.e both coal and OB outsourcing.

1.5 DIFFICULTIES AND CONSTRAINTS IN MINING WITH ASSOCIATED RISK

(i) The nearest railway siding is Govinda Railway siding which is

situated at a distance of about 5.0Km from the mine. The railway

line extension from Bhaiyatola station is required to connect the

upcoming Amadand siding.

(ii) Rehabilitation & resettlement of four villages namely Nimha,

Timkitola-Amadand, Harratola-Kuhka and Majholi are involved in

the project. Acquisition of land alongwith R&R of PAP is a critical

activity and should be taken up on top priority.

1.6 PEAK CAPACITY Sometimes with favorable geo-mining conditions and improved

productivity of the HEMM, the project may produce coal upto 1.35 times of


JOB NO.-515126 ES / 7 of 39

the planned capacity. So, EMP should be prepared for 5.40 Mty,

accordingly approval from the Competent Authority is to be sought.

1.7 FLEXIBILITY IN IMPLEMENTATION The flexibility in the implementation stage may be exercised within the

approved cost estimates to respond to improvements in technology and

equipment which would result in improved profitability and productivity

measures. Following points may be considered under the flexibility: -

a) Re-alignment of project working for better working layout / dump etc.

b) Change in the specification of HEMM, for techno-economic consideration,

to higher capacity at the time of procurement of new equipment or

replacement of the equipment.

c) To procure state-of-the-art safety equipment, whenever they are

introduced, even if the same is not provided in approved Project Report.

d) Relocation of site for infrastructure facilities depending upon techno-

economic reasons and availability of land / forest area etc.

e) Hiring of equipment for loading, transportation etc., at a competitive price,

so as to cater to the needs of increased demand of coal and subsequent

removal of higher OB and for augmentation of coal production.

f) For upgradation of new technology in mining method for improving

performance and reduction in manpower, at a subsequent date after

project completion.

g) In this PR it is proposed that coal would be mined by surface miner.

However, in circumstances where Operational/Geotechnical difficulties

persist small quantity of coal may be mined out by alternative technology

such as ripping/drilling etc. Prior approval may be obtained for use of

alternative technology citing the circumstances/operational difficulties.

1.8 CRITICAL ACTIVITIES PRIOR TO ENVIRONMENT CLEARENCE

Critical activities, which could be taken up prior to environmental, forestry

and other statutory clearances to expedite project implementation are as given

below.


JOB NO.-515126 ES / 8 of 39

a) Northern boundary of quarry is to be exposed upto UK seam along the

full strike length of the quarry. This is required to reach quarry floor of 4.0

Mty report to create internal dumping space at the earliest.

b) The acquisition of R&R site should be processed to take possession of

the R&R site to rehabilitate the project affected family at the earliest.

c) The northern side garland drain is to be constructed first to prevent inrush

of water from northern side. As quarry advances towards the south, the

other garland drains will be constructed as per requirement.

d) Preliminary study about extension of railway line and its tentative

alignment from Bhaiyatola rail station or other suitable location is to be

done to connect Amadand Siding.

5.1 MINE BOUNDARIES

The quarriable area for the opencast mining is shown on Plate No.3 &

Figure-5.1. One quarry on floor of Seam LK-II has been planned. The

boundary of quarry has been fixed as follows: -

North : Incrop of Upper Kotma Seam

Reason- Beyond UK seam incrop the stripping ratio is

high (more than 20).

South : Incrop of Upper Kotma Seam


JOB NO.-515126 ES / 11 of 39



East : A line keeping 100 m barrier from boundary of Amadand

Village and Pendra-Manendragarh road.

Reason-. Amadand UG and Bartarai UG mine is operating

on the other side of road.

West : Incrop of Upper Kotma Seam

Reason- Beyond UK seam incrop the stripping ratio is high

(more than 20).

Khodri Block has not been included in the proposed mine area. The

incrop of coal seams also exists in the northern side of Khodri Block.

Thus, Khodri Block can be extracted from the northern side of the block

as a separate mine.

5.2 MINEABLE RESERVES

As on 01.04.2015, the total mineable reserves within the quarry have

been estimated as 70.46 Mt with a corresponding OB volume of 764.40

Mcum. The already extracted coal & OB removal has been deducted to

get the balance remaining coal & OB quantity. While, calculating

mineable reserves, a geological loss of 10% and a mining loss of 10%

have been considered.

6.1 MINE PARAMETERS The geological and mining characteristics of both the quarries have been

summarised in the following table: -

Haul roads have been planned at a maximum gradient of 1 in 16, the width

of the haul road has been kept as 30 m for two way dumpers transport. Two

batter road of 50m width will be maintained along UK seam & MK seam for

laying side road and inpit belt conveyor.(details given in chapter 11)

6.3 EQUIPMENT SELECTION

In this PR, Coal and OB is proposed to be worked by outsourced

equipment. OB is proposed to be excavated by shovel dumper

combination. It is envisaged that coal would be mined by surface miner. In

this PR it is proposed that coal would be mined by surface miner. However,

in circumstances where Operational/Geotechnical difficulties persist small

quantity of coal may be mined out by alternative technology such as

ripping/drilling etc. Prior approval may be obtained for use of

alternative technology citing the circumstances/operational difficulties.

In the outsourcing option blasting will be done departmentally and

both OB and coal will be worked by outsourcing. To handle the larger OB

quantity optimum no. of equipment with optimum capacity is proposed be

used. Due to flexibility of operation, Shovel-Dumper combination will be


JOB NO.-515126 ES / 14 of 39

suitable for OB removal for working multiple seams and partings.

Considering huge volume of OB removal higher size of HEMM like 10

cum Shovels with 100T rear dumpers may be used for OBR by

outsourcing agency. For thin partings, smaller backhoe may be used.

Few auxiliary HEMM has been given for mine development and

reclamation related work. Transport of coal from face to railway siding

will be done by inpit belt conveyor & surface belt conveyor.

The property is free from any major geological disturbances. Average

gradient of quarry floor is 1 in 30. The average strike length of the quarry

is 3.0 km. Thus, sufficient face length will be available for optimum

efficiency of surface miner.

The bottom most seams LK-2 have been splitted into LK-2 Top and LK-2

Bottom. Both of the splits have varying thickness from 0.7 m to 1.50m.

Above LK-2 Seam, Seam L-1 exists having seam thickness 0.70m to

0.90m. Parting thickness between Seam LK-2 and L-1 varies 6 m to 18

m. Thus, dragline horizon changing will be required for operation of

dragline and dragline productivity will be less. Besides, the bottom coal

bench may be diluted as low thickness coal seam may be mixed with OB

during dragline operation. Considering multi-seam working and wide

variation of parting OB, dragline has not been proposed in this Project

Report.

6.4 MINING SYSTEM & SYSTEM PARAMETERS

Surface miner has been proposed for extraction of coal.

The salient features of mining system are as follows:-

i) Height of bench in OB will depend on the size of equipment.

Coal bench height will depend on the thickness of the coal seams.

The provision of coal mine regulations and related circulars shall be

strictly followed for designing bench parameters in coal and OB.

ii) Average Seam gradient – 1 in 30.


JOB NO.-515126 ES / 15 of 39

iii) Total dump height – Internal dump height is 230 m from quarry

floor but it will be 90m from surface. External dump height is 120m

from surface.

7.1 CONSTRAINTS ON MINE DEVELOPMENT (i) The nearest railway siding is Govinda Railway siding which is








7.2 MINING STRATEGY / MINING SEQUENCE

At present Amadand OC is a running mine with a peak coal production of

1.15Mty and it is already extracting coal from UK seam.

It is proposed to expose MK seam in the 2nd year of mine operation by

grading properly the access trench and making its width 30 m wide and

gradient at 1 in 16. Then sufficient area to be exposed in the MK seam

floor. In the 3rd year of mine operation, the access trench is to be graded

at 1 in 16 to touch the mine floor at LKII seam of about 405 m R.L.

The quarry floor is developed in such a manner so as to facilitate

the proper drainage of water towards the sump. This would also facilitate

extension of coal and OB bench for full development of mine. After

creation of sufficient decoaled area, internal backfilling of OB will be

started in the 4th year. The coal production will continue from the 1st year

of mine life and the target coal production of 4.00 Mty will be achieved in

the 3rd year.

Two batter road of 50m width will be maintained along eastern side

batter. One batter road along floor of UK seam will be used to place inpit

belt conveyor to carry coal from UK & L4 seam as shown in plate 3.


JOB NO.-515126 ES / 16 of 39

Other batter road along floor of MK seam will be used to place inpit

belt conveyor to carry coal from MK, L3 & LK1 seam. One another

inclined inpit belt conveyor will be placed upto floor of LKII seam to carry

coal from LKII & L1 seam.

Finally, through inclined belt conveyor all the coal will be transported to

surface as shown in the plate-3. From pit top coal will be transported to

upcoming Amadand siding through surface belt conveyor. .(details given

in chapter 11)

For reducing the external dump area and healthy operation of mine, 2

plans i.e. final stage of mine excavation and final dump plan showing

backfilling, Plate No. 3 & 4 are enclosed. The life of mine will be 19 years.

7.3 TOP SOIL MANAGEMENT Initially, the soil/alluvium from top bench of OB will be stacked and stored

separately. The stock piling of topsoil will be as follows:

i) Top soil removed shall be stock-piled till sufficient area is making

available to spread such materials immediately on re-graded

areas.

ii) Stock-piled Top soil shall be selectively placed on a stable area,

not disturbed, and protected from wind and water erosion,

unnecessary compaction, and contaminants which lessen the

capability of the materials to support vegetation when redistributed.

iii) After the final grading the stacked top soil would be redistributed

in a manner that achieves an approximate uniform stable

thickness consistent with the post mining land uses, contours,

and surface water drainage system.

The top soil quantity will be about 3.0Mcum. Provision of placing of

top soil over final dump has been considered in project costing.


JOB NO.-515126 ES / 17 of 39

7.4 DUMPING STRATEGY In the initial years i.e. upto 4th year, entire OB will go to the external

dumps. For project implementation and aquision of land for external

dump may take 3 to 4 years. During this period about 20 Mcum OB will

be dumped internally. Provision of rehandling of this internal dump to

external dump site has been considered in the project costing.

Internal dumping will start from the 4th year onwards. The parting OB in

case of older seams may be transported partly through central haul road,

while mining in the multi seam zone.

Initially, the soil/alluvium from top bench of OB will be stacked and stored

separately. The spoil dump benches in the internally backfilled OB will be

in the form of benches. With the sufficient advance of coal production

bench, the backfilled OB will be leveled with dozer.. Dumper/Tipper will

transport soil/alluvium OB from the top OB bench and will dump the soil

directly on the leveled backfilled OB. The barrier distance between

internal dump and coal production bench will be 100 m to have smooth

functioning of machineries.

The slope stability study should be done. According to study report, the

dump design like dump bench height, total dump height & slope etc.

should be modified to avoid dump failure. In addition to that proper

precautions should be taken to avoid sliding of internal OB bench. is

estimated that 238.02 Mcum OB will be externally dumped outside quarry

area from 1st year to 10th year for which 356.50 Ha land will be required.

The northern boundary of Amadand OC block is along the Fault F1-F1

having throw of 20m to 80m. On the other side of Fault F1-F1 Khodri

Block exists where UK seam occurs at a minimum depth of about 21m.

So external dump has not proposed in the Khodri Block.

External dump has been made near southern boundary as shown in

Plate No.4. The break-up of OB quantity to be accommodated in various

dumps is as follows:-


JOB NO.-515126 ES / 18 of 39

Dump OB accommodated in Mcum 1. Internal dump 526.38 2. External dump outside Quarry area 238.02

Top soil will be removed and stored separately. This soil will be directly

spread over the leveled graded backfilled spoil for reclamation of the

quarried out land.

Possibility of external dump within quarry boundary and rehandling back

into the quarry has been examined. Considering the high quantity of

external OB placing of external dump within quarry boundary will not to

be feasible. So placing of external dump proposed outside the quarry

area.

Amadand OC may be expanded in the east direction. Quarry planning

and dump plan has been proposed accordingly such that quarry can be

expanded in east directions in future. At the end of quarry life, if required,

the void left will be filled to reduce the depth of void to 60m. Necessary

filling of the void will be done from mine closure cost. Initially the height of

internal dump is 90m from surface. After ffteenth year of mine life the

internal dump height will be kept upto surface level. Thus after mining is

CHAPTER – I INTRODUCTION

1.1 BACKGROUND OF THE PROJECT REPORT

The Amadand Opencast Block is located in the eastern part of south Sohagpur

Coalfield and is flanked by working mines of Hasdeo and Jamuna & Kotma

areas of South Eastern Coalfields Limited (SECL) to the east and west

respectively.

The detailed exploration of the area was taken up by CMPDI in August 1990

and comprehensive geological information were provided in Geological Reports

on Bartarai Block in December 1993, Amadand Opencast area in December

1995, Bakulmuni Block in July 1997, Amadand East U/G Block in January 1998

and Amadand West U/G Block in November 1999.



submitted to SECL in August 2003 and approved in Sept 2003. During

preparation of Amadand OC (1.15 Mty) report, lower seams e.g. MK (Top) and

MK (Bottom) and LK-II were also considered for extraction by opencast

method. But, due to high stripping ratio, the quarriability of lower seam were not

feasible for departmental option. So seams below UK seam were not

considered in the 1.15 Mty PR.

Latter on, decisions were taken to extract coal from bottom seams.

Accordingly, Revised Geological Report have been prepared, considering

workable coal seams upto bottom most LK-II seam which has not taken into

account for opencast mining earlier. In the area under consideration seams, L-

6, L-5, UK (Top), UK (Bottom), UK, L-4, L-3(Top), L-3 (Bottom), L-3, MK (Top),

MK (Bottom), MKC, L-2, LK-I, L-1, LK-II (Top), LK-II (Bottom) & LK-II have

encountered in descending order.

The present report is formulated considering all the seams upto bottom most

LK-II seam for mining with outsourcing option.

The area was identified by CMPDI for scout drilling in March 1989 on the basis of

some boreholes drilled close to some of the GSI boreholes, namely, SM-4, 6&8

etc. in the eastern part of the Amadand tract and DGM (MP) was entrusted for

scout drilling. The results of the scout drilling conducted by DGM (MP) revealed

presence of good quality workable coal deposit in an area of about 60 sq.km of

the intervening Amadand tract between the working mines of SECL.

Detailed exploration of the area was taken up by CMPDI in August 1990 and

comprehensive geological information was provided in Geological reports on

Bartarai Block in December 1993, Amadand Opencast area in December 1995,

Bakulmuni Block in July 1997, Amadand East U/G Block in January 1998 and

Amadand West U/G Block in November 1999.

The block measures 15.061 sq.km. which includes 14.154 sq.km. free area

Outsourcing IRR is more than 12%.

Based on above observations, the horizontal boundary of quarry area is

mostly same as proposed in Amadand OC 1.15 Mty report and vertical

boundary proposed upto the bottom most LKII(Bot) seam. From environmental

point of view Inpit belt conveyor and surface belt conveyor to transport coal

from pit top to siding has been considered in this Amadand OC Opencast (4.0

Mty) report. Rapid loading system has also been considered. Thus increasing


. . JOB NO.-515126 Chapter 1 / 6 of 11

production capacity from 1.15Mty to 4.0Mty is justified to meet the increased

growth of demand.

To consider all the coal seams upto bottom most LK-II seam, a Revised

Geological Report have been prepared, considering all workable coal seams in

this area which has not taken into account for opencast mining earlier. In the

area under consideration, four main coal seams UK, MK, LKI & LKII exists and

in addition to that three local coal seams L1, L3 & L4 exists. The seams UK,

MK, LKII & L3 are splitted into top and bottom within the proposed quarry area.

1.2.2 Exploration Design

A total of 228 boreholes involving 27121.07m of drilling have been

considered for preparation of this report. Core recovery in coal and non coal

is generally above 85% & 70% respectively except in few boreholes e.g.

CMAD-72, 153, 164, 177, 184 etc. Boreholes have been spaced generally

400m apart except in case of structure proving boreholes. Depth range of

boreholes is from 17m to 206m. Density of boreholes per sq. km. is 15.20.

1.3 MINING ACTIVITIES

1.6 DIFFICULTIES AND CONSTRAINTS IN MINING WITH ASSOCIATED RISK

(i) The nearest railway siding is Govinda Railway siding which is situated

at a distance of about 5.0Km from the mine. The railway line extension

from Bhaiyatola station is required to connect the upcoming Amadand

siding.

(ii) Rehabilitation & resettlement of four villages namely Nimha, Timkitola-

Amadand, Harratola-Kuhka and Majholi are involved in the project.

Acquisition of land alongwith R&R of PAP is a critical activity and

should be taken up on top priority.

1.7 PROJECT OBJECTIVES AND TARGET BENEFICIARIES The demand projection from SECL for the year 2016-17 is 270.37 Mt. It will cater

to the needs of the upcoming industries like Cement, Fertilizers, other industries

etc. The projected availability in the year 2016-17 is 150.00 Mt and there will be

shortage of 120.37 Mt as shown in Table 2.1. .

1.8 PEAK CAPACITY Sometimes with favorable geo-mining conditions and improved productivity of the

HEMM, the project may produce coal upto 1.35 times of the planned capacity. So,

EMP should be prepared for 5.40 Mty, accordingly approval from the Competent

Authority is to be sought.

1.9 FLEXIBILITY IN IMPLEMENTATION The flexibility in the implementation stage may be exercised within the approved

cost estimates to respond to improvements in technology and equipment which

would result in improved profitability and productivity measures. Following points

may be considered under the flexibility: -

a) Re-alignment of project working for better working layout / dump etc.

b) Change in the specification of HEMM, for techno-economic consideration, to

higher capacity at the time of procurement of new equipment or replacement of

the equipment.

c) To procure state-of-the-art safety equipment, whenever they are introduced,

even if the same is not provided in approved Project Report.

d) Relocation of site for infrastructure facilities depending upon techno-economic

reasons and availability of land / forest area etc.


. . JOB NO.-515126 Chapter 1 / 11 of 11

e) Hiring of equipment for loading, transportation etc., at a competitive price, so as

to cater to the needs of increased demand of coal and subsequent removal of

higher OB and for augmentation of coal production.

f) For upgradation of new technology in mining method for improving

performance and reduction in manpower, at a subsequent date after project

completion.

g) In this PR it is proposed that coal would be mined by surface miner. However,

in circumstances where Operational/Geotechnical difficulties persist small

quantity of coal may be mined out by alternative technology such as

ripping/drilling etc. Prior approval may be obtained for use of alternative

technology citing the circumstances/operational difficulties.

1.10 CRITICAL ACTIVITIES PRIOR TO ENVIRONMENT CLEARENCE

Critical activities, which could be taken up prior to environmental, forestry and

other statutory clearances to expedite project implementation are as given below.

a) Northern boundary of quarry is to be exposed upto UK seam along the full

strike length of the quarry. This is required to reach quarry floor of 4.00 Mty

report to create internal dumping space at the earliest.

b) The acquisition of R&R site should be processed to take possession of the

R&R site to rehabilitate the project affected family at the earliest.

c) The northern side garland drain is to be constructed first to prevent inrush of

water from northern side. As quarry advances towards the south, the other

garland drains will be constructed as per requirement.

d) Preliminary study about extension of railway line and its tentative alignment

from Bhaiyatola rail station or other suitable location is to be done to connect

Amadand Siding.

GEOLOGY AND DEPOSIT APPRAISAL

4.1 INTRODUCTION

4.1.1 The Amadand Opencast Block is located in the eastern part of south Sohagpur

Coalfield and is flanked by working collieries of Hasdeo and Jamuna & Kotma

areas of the SECL to the east and west respectively.

The area was identified by CMPDI for scout drilling in March 1989 on the basis

of some boreholes drilled close to some of the GSI boreholes, namely, SM-4,

6&8 etc. in the eastern part of the Amadand tract and DGM (MP) was entrusted

for scout drilling. The results of the scout drilling conducted by DGM (MP)

revealed presence of good quality workable coal deposit in an area of about

60sq.km. of the intervening Amadand tract between the working collieries of

SECL.

A detailed proving of the area was taken up by CMPDI in Aug.1990 and a

comprehensive geological information was provided in Geological Reports on

Bartarai Block in Dec.'93, Amadand Opencast area in Dec.'95, Bakulmuni Block

in July'97, Amadand East U/G Block in January 1998 and Amadand West U/G

Block in Nov.’99.

The Amadand Opencast Area has been prepared after considering the Upper

Kotma seam only. However, the present report is prepared at the behest of

Mining Department, considering the area of aforesaid 4 reports in part or total

from the opencast stand point considering all the seams. Accordingly the data

have been re-processed, boreholewise from underground norms to opencast

norm and many coal seams and/coal bands intersected in boreholes, earlier not

taken into account, have been considered along with their naming. Wherever

necessary, earlier splits of seams have been merged, as per the revised norms

considered for opencast mine. In the area of present seams, L-6, L-5, UK (Top),

UK (Bottom), UK, L-4, L-3(Top), L-3 (Bottom), L-3, MK (Top), MK (Bottom),

MKC, L-2, LK-I, L-1, LK-II (Top), LK-II (Bottom) & LK-II have encountered in

descending order.

4.2.4 Reliability of data and degree of confidence (based on statistical analysis)

1) In the absence of any surface exposure of the strata, the report is based

entirely on the data obtained from 228 boreholes drilled by CMPDI and

DGM (MP) falling within Amadand OC Block.

2) The area shows variable dip, and the area is devoid of fault. However, the

possibility of faults of smaller magnitude cannot be entirely ruled out in the

area. Though all care has been taken to precisely delineate the incrops of

seams on the basis of borehole data, there is a possibility of minor

variation as the exact pattern of local weathering is not known.

3) The statistical analysis of borehole data has been carried out separately for

different seams for estimating Mean and Standard Deviation of different

parameters is given below:

4.3.4 Structural setting within the project area

The featureless rolling topography and a thick soil cover in and around Amadand

Open Cast Block have completely masked the surface expression of the

structural elements. The entire structural set-up of the area, therefore, has been

worked out on the sub-surface data obtained through boreholes. It shows that


. . JOB NO.-515126 Chapter 4 / 8 of 81

the Amadand Open Cast Block is located in the central part of the broad

basinal structure in the Amadand sub-basin intervening Jamuna & Kotma and

Jhagrakhand sub-basin and the same is presented in the form of Geological Map

(Plate-II).

4.3.5 STRIKE AND DIP

In the southern part of the block the strike is roughly E-W with 1o-2o northerly dip.

In the north-eastern part of the block the strike is roughly NW-SE with 2o-4o

south westerly dip. In the north eastern part of the block the strike is roughly E-

W with 1o to 3o southerly dip. In the western part of the block the dip of the strata

is less than a degree to almost flat. The overall structure may be attributed to the

depositional rolling nature of basin configuration.

4.3.6 PATTERN OF FAULT

The considered area is devoid of any fault. Earlier while preparing Amadand

Opencast area report, faults were interpreted but in due course after receipt of

more data of boreholes the possibility of faults was ruled out.

4.3.7 INTRUSIVES

Dolerite has been intersected in borehole no AMD-8 at the depths of 168.60m &

172.50m, located in the northern part of the block. From intersection it has been

surmised that the intrusive body has a discordant relation with the host rock. The

magnetic survey conducted in the area has confirmed the above postulate and

has delineated a single E-W trending, 24m-60m thick dyke. From the magnetic

intensity data, the dyke has been inferred to occur at a shallow depth in the

northern part of the block. Either the dyke occurs at a considerable depth or it is

highly weathered near the surface. No other dolerite body has been picked up in

the magnetic survey scanning in the balance part of the area.


. . JOB NO.-515126 Chapter 4 / 9 of 81

4.4 DESCRIPTION OF INDIVIDUAL COAL SEAMS 4.4.1 SEAM-L6

Seam L6 is the top most from the surface within the Barakar Formation.

No splitting in this seam is observed in the block area.

This seam is intersected in 22 boreholes restricted in the central part of the block

area. The thickness range varies between 0.09m to 1.37m with more than 0.50m

thickness in 12 boreholes. The average thickness is 0.62m. Minimum parting in

respect of Seam L5, down below is 4.11m (CMAD-340) whereas the maximum

parting is 11.56 m (CMAD-271).

As the seam is having low thickness, not covering the considerable area in the

block and paucity of analytical data, Seam L6 is not considered for reserve

estimation as well as for structural interpretation.

4.4.2 SEAM-L5

This seam is second from the surface. This Seam is intersected in 58 boreholes.

The minimum thickness of 0.05m is observed in borehole No.CMAD-15 and

maximum thickness of 0.88m is observed in borehole No.CMAD-36. The seam is

having more than 0.50m thickness in 10 boreholes only. Though the Seam L5 is

more persistent than Seam L6, the workable area is distributed in patches. The

band-by-band analysis and proximate analysis are available for seven and four

boreholes respectively .The seam is not considered for reserve estimation.

C. STRATIGRAPHIC POSITION

Seam-UK Top being the top most split of Seam Upper Kotma is the third from

surface within the Barakar Formation.

D. PARTING In the block area this is the topmost workable coal seam. The seam occurs at a

minimum depth of 10.15m (CMAD-152, 332, 339) from the surface in the north

eastern and south western parts of the block and at a maximum depth of 28.40m

(CMAD-63) in the south central part of the block.

The parting between UKT & UKB seams predominantly consists of arenaceous

facies represented by sandstone. Since coal seams UKT & UKB are merged at

places, parting between them ranges between 0.00m to 5.36m (CMAD-343).

E. THICKNESS

It is observed that the minimum thickness of 0.30m is intersected in borehole

No.CMAD-63 and maximum thickness of 2.80m is intersected in borehole

No.CMAD-62. The average thickness of seam is 1.65m. Since Seam UKT is

having workable thickness in patches in major part of the block area, it is

described in detail and also considered for assessment of availability of coal

reserves.

F. SPLITTING

This seam does not show splitting in the block area.

G. OUTCROP/INCROP

The seam incrops to represent a broad basinal structure with its E-W longer axis

alongwith corresponding centripetal dip. The position of incrop is below the

weathered mantle.

H. ROOF & FLOOR

The immediate roof of Seam-UKT consists predominantly of coarse grained

sandstone, at places it is clay and sandy soil also. The immediate floor consists


. . JOB NO.-515126 Chapter 4 / 11 of 81

of predominantly sandstone and sandy shale. At places, occasionally fine

grained to medium grained sandstone and carbonaceous shale are also found.

D. PARTING

In the block area seam occurs at a minimum depth of 3.05m (CMAD-523) from

surface in the western part of the block and maximum at a depth of 37.35m

(CMAD-35) also in the western part of the block.

The parting between Seam UK and Seam L4 predominantly consists of

arenaceous facies represented by sandstone. The parting between Seam UK

and Seam L4 ranges between 8.74m (CMAD-8) and 28.65M (CMAD-12) in the

eastern part of the block.

E. THICKNESS

It is observed that the coal seam thickness ranges between 0.45m (CMAD-51)

and 6.87m (CMAD-325). The seam exhibits a general reduction in its thickness

from east to west. The seam deteriorates into clay and carbonaceous shale in 22

and 2 boreholes respectively.

F. SPLITTING

The seam shows splitting into two seams (UKT & UKB) at various places, mostly

near incrop region. The splitting is due to development of parting ranging from

1.03m to 5.36m.

G. OUTCROP/INCROP

The seam’s incrop is in elliptical fashion in conformity to the basinal configuration

of the deposits. In the incrop regions, the seam in general has been observed to

deteriorate into clay in 22 boreholes and into carbonaceous shale in 2 boreholes.

The incrop shown is generally below the weathered mantle except near borehole

nos. AMD-05, CMAD-72, 80, 101, 172, 192, 282, 283 & 328 in which seam has

deteriorated and occurrence is within weathered zone. The incrop is shown upto

the borehole to avoid the confusion of up dip position of boreholes

H. ROOF & FLOOR

The immediate roof is generally sandy soil or clay. The floor of seam consists of

mainly sandstone.

I. DIRT BANDS

This seam contains impersistent dirt band. The lithology of dirt band is either

carbonaceous shale or shale. In the northern and central part of the area dirt

band is closer to the roof whereas in the southern part of the area it is located

closer to the seam floor.

the south eastern part and at a maximum depth of 87.15m (CMAD-39) from the

surface also in the north eastern part of the block.

The parting between MKT and MKB predominantly consists of arenaceous

facies. It is also carbonaceous shale, sandy shale occasionally. The parting

between aforesaid seams ranges between 0.94m (CMAD-91) and 16.23m

(AMD-2). It is generally observed that the parting between MKT & MKB seams


. . JOB NO.-515126 Chapter 4 / 33 of 81

increases from west to east in the northern part. In borehole no CMAD-91,

parting between MKT & MKB is 0.94m and the seam is taken as split because

MKT is carbonaceous shale and its merger with seam MKB will deteriorate the

quality of the seam MKC.

F. THICKNESS

It is observed that minimum thickness of 0.04m is found in borehole No.AMD-15

and maximum thickness of 3.44m in borehole No.CMAD-273. The seam is

deteriorated into carbonaceous shale in 21 boreholes.

4.5.2 Hydro-geological details:

Surface water:

Regionally, the Son River and its tributaries mainly control the drainage system

in the area. Kewai River, a major tributary of Son River flowing close to the

western boundary of the mine, in a north east to south west direction, is the

master drainage of the study area.

The block area is traversed by a small first order stream Banki Nala in the south-

west. Bhirwa Nala is flowing along the south eastern part of the project. Both

Banki Nala and Bhirwa nala is flowing towards south west direction and finally

they merge and discharge into Son River as Bhirwa nala.

Another important river close to the eastern boundary of the mine is Jhiria Nala

which is flowing in the North-east to East direction and finally merges with

Kulhariya Nala. Kulhariya nala is draining the north eastern part of the study

area. It is flowing form north to east and finally discharge into Hasdeo River.

The other streams which drain the buffer zone are Hendri Nala in north,

Bukbuka Nala, Bathi Dhar, Khari and Jhimar Dhar in east, Neori nala and

Keraha Dhar in south east. The drainage pattern in the area is mostly dendritic in

nature.

Groundwater:

The formations within the study area are Gondwanas and Talchirs. Major portion

of the area is occupied by Gondwanas and the rest by Talchirs. The project area,


. . JOB NO.-515126 Chapter 4 / 64 of 81

situated on Barakar sand stone formation, comprises soil cover, weathered

mantle and sand stone of different grain sizes with shale beds and coal seams.

The weathered mantle and sand stone beds are saturated, and behave as

aquifers whereas the shale beds and coal seams as aquicludes. Due to

stratification and with the presence of aquicludes (shale/coal), a multi-aquifer

system is developed.

Eleven coal seams developed in the block and all the seams are selected for

opencast mining. The seams are centrally dipping and the gradient of the seams

area 1 in 30.

The alluvium formation and weathered Barakar formation comprising mainly of

loosely cemented and poorly consolidated grey coloured medium to coarse

grained sandstone lying above the Upper Kotma (Top) & Upper Kotma Combine

coal seams with a thickness varying from 20.0 m to 40.0 m behave as

unconfined aquifer. This unconfined aquifer is potential and prolific. The lower

formations, consisting of compact and fine to medium grained sandstone with

occasional sandy shale, carbonaceous shale and shale intercalation, with

secondary porosity, behave as semi-confined to confine in nature.

The general hydro-geological units developed in the Amadand block area are as

follows:

Hydrogeological Unit

Formation Thickness

Phreatic aquifer (A)

Soil & Alluvium, loosely cemented, poorly consolidated medium to coarse grained weathered sandstone & intercalation of shale and sandstone.

20.0 m – 40.0 m

Aquifer Parameters

No detailed hydrogeological investigation has been carried out in the present

mine block. However, hydrogeological investigations were carried out by

CGWB & CMPDI in Jamuna coalfield, where the mine is situated, under S&T

project," Studies on Groundwater Flow into Coal Mines." The aquifer parameters

for the formation lying above the working seam (i.e. multi-aquifer) were reported

as:

Transmissivity (T) : 175 m2/day

Permeability (k) : 5 m/day

Storage coefficient : 5.0 x 10-4


. . JOB NO.-515126 Chapter 4 / 66 of 81

So also, detailed hydrogeological investigations were carried out at Bartarai UG

project just adjacent to Amadand OC Project, located in Jamuna-Kotma Area,

the aquifer parameters for lower aquifer were evaluated by SECL and reported

the permeability as 0.25 m/day.

The pre and post-monsoon water levels of Khodri station show decreasing

trends whereas the pre monsoon water level trend at Payari shows increasing

trend and post-monsoon water level trends at Payari station show marginal

decline. This upward trend may be attributed to the water conservation and

utilization of surface water for irrigation use in the area. The decline in pre and

post-monsoon water level at Khodri village may be attributed to increase in

ground water utilization due to increase in the local population and the irrigation

draft and .decrease in rainfall.

Groundwater Stage of Development:

Except for coal mining, no major industrial development activity is located in the

area. Due to dominant forest area and backwardness the groundwater

development in the area is very insignificant. As per CGWB, NCC Region, Raipur,

the total annual replenishable ground water resource in the Anuppur Development

Block, Shahdol district (where Amadand Block exists), was assessed as 68.20

M.Cum. It was also reported that the ground water development in the block is as

1.99 % and falls within category "Safe". As such, the entire Madhya Pradesh &

Chhattisgarh States are covered under the category “Safe”.

Water Quality:


. . JOB NO.-515126 Chapter 4 / 70 of 81

Under routine environmental monitoring, the surface, groundwater and mine

water quality, for all the operating mines in the area, have been monitored and

found to be well within the permissible limits of stipulated standards. Mine water

and other effluents have been treated before disposal and usage.

Mine Drainage:

In sedimentary rocks, due to stratification, the horizontal permeability (KH) is

many folds higher than the vertical permeability (KV). The permeable beds act as

individual hydrogeological units and develop a multi-aquifer system. Thereby, the

groundwater velocity / flow along the bedding plane are higher than across the

plane. The opencast mine can be simulated as a large diameter well and the

inflows are contributed mainly from the saturated formation lying above. Thus,

the mine inflow is directly proportional to the aquifer and mine parameters.

In the initial stage the mine inflow is in proportion to the rate of mine expansion.

With the presence of low permeable formations, the inflow is significantly small.

In due course of mining, due to partial de-saturation of the aquifer, the inflow

reduces and gets stabilized.

Presently, in Amadand Opencast mine, the permeable formations lying above

the deepest working seam (Lower Kotma II Bottom) are mainly composed of

sandstone with occasional intercalation of shale, sandstone and sandy shale.

The present depth of workings is about 35m against an ultimate planned depth

of 150m. The present mine discharge during dry period is estimated as 3,928

m3/d, which can be considered as the ground water inflow into the mine.

Disposal of Mine water:

To meet the safety of the mine and create good working conditions, it is necessary

to discharge the mine water collection onto surface. To collect the present mine

water inflow from the operating two quarries (Departmental Patch and Contractual

Patch), three sumps with a total holding capacity of about 65,000 cum. (i.e.

Departmental Patch = 24,000 + 9,000 cum & Contractual Patch = 32,000 cum) are

existing and equipped with suitable sumps. The main sump floor RL in

Departmental Patch is 510.00 m. whereas, the sump floor RL in Contractual Patch


. . JOB NO.-515126 Chapter 4 / 71 of 81

is 505.00 m. As the mine is in the starting phase and because of lack of adequate

storage space within active mine area, so, most of the monsoon water collection

has been discharged on the surface. As such the entire industrial water demand

has been met from mine water only.

To handle the inflow 9 pumps (3 Nos. @ 1000 gpm, 6 Nos. @ 700 gpm), including

standby, with a total discharge capacity of about 7,200 gpm (545 LPs) are

operating in both the working quarries. As such, the monsoon water collection has

been stored in the sumps and only the overflow of these sumps has been

discharged.

The present mine water discharge varies from about 21,210m3/day during peak

monsoon period to about 3,928 m3/day in lean period. Thereby, the average

pumping (120 days rainy period + 245 days lean period) from Amadand OCP is

9,610m3/day. This discharge includes both rainwater collection and groundwater

seepage into the mine.

This stored water has been effectively utilized for industrial purposes within mine

premises, such as, mine operation, dust suppression, CHP, workshop, greenbelt

development and fight fighting uses. Most of the mine water has been discharged

after sufficient settling time. Thereby, the discharged water is almost clean with

very less TSS load. The mine water after settling in mine sumps has been

discharged to various utility points and excess water / overflow has been

discharged into the adjacent ponds and irrigation land for local users.

During monsoon, part of the mine water has been discharged on down dip for

irrigation use, the overflow of which will ultimately reach the adjacent Banki Nala

flowing in the southern part of the mine. Because of clean water in sufficient

quantity is available for local irrigation, the crops in these villages are protected.

4.6 GEOLOGICAL RESERVES

4.6.1 BRIEF METHODOLOGY FOR RESERVE ESTIMATION

Estimation of quarriable reserves has been made on the following considerations:

(i) The effective thickness of the seams considered for quarriable reserves

includes all combustible and non-combustible bands upto 0.10m,

(ii) All bands of more than 0.10m thickness irrespective of their lithology have been

excluded from seam thickness for arriving at effective seam thickness in the

case of quarriable proposition.

(iii) All the unworkable coal bands/coal sections occurring above/below the

delineated roof/floor of the seam sections and also those occurring within the

seam partings have been added to the overburden.

(iv) The cumulative thickness of all bands excluded from the seam thickness has

been added to the seam burden.

(v) For estimation of quarriable reserves, thickness ranges of 0.50 to 0.90m, 0.90

to 1.20m, 1.20 to 1.50m, 1.50 to 2.00m, 2.00 to 2.5m and 2.5m to 3.00m and so

on, have been considered.

(vi) The minimum thickness considered for reserve estimation has been taken as

0.50m as desired by Mine Planners.

(vii) The influence area around the borehole in which seam has deteriorated to

carb.shale, shale or clay has not been considered for reserve estimation.

(viii) Thickness and quality values of seams in boreholes have not been considered

wherever values are not in conformity of surrounding boreholes. For instance,

in case of MKT Seam values of boreholes AMD-15, CMAD-62, 115, 121, 127

and 243 and for Seam L-1, values of borehole CMAD-64 has not been

considered

CATEGORAIZATION OF RESERVES

The entire reserves of fifteen coal seams viz. UKT, UKB, L4, L3T, L3B, L3,

MKT, MKB, MKC, LKI, L1, LKIIT, LKIIB & LKII, have been placed under 'Proved'

category as per Indian Standard Procedure.


. . JOB NO.-515126 Chapter 4 / 73 of 81

Although, forest area has been shown to occur nearly at southern and in the

north-eastern part of the block, where drilling could not be possible, there is

hardly any difference between two boreholes of around 50-100m after

considering the area of influence of 200m to satisfy the norms of indicated

reserves. Therefore, all the reserves are considered to be covered under

“Proved” category.

To obtain net in-situ geological reserves, a total deduction of 10% has been

made from the estimated gross reserves to compensate for loss on account of

faults and other unforeseen geological conditions.

METHODOLOGY

The volume of coal reserves has been calculated by volumetric method.

Volume (mm3) = Area (in sq.km.) x thickness (m) considered.

The seam thickness and grade between various borehole points have been

extrapolated and depicted by drawing isochores & isogrades.

SPECIFIC GRAVITY

For the purpose of converting volume of coal into tonnage, specific gravity of

1.40, 1.42, 1.47, 1.52, 1.58, 1.67 and 1.70 has been assumed for grades A, B,

C, D, E, F and G respectively.

COMPUTATION OF COAL RESERVES

The isochore method has been used for estimation of reserves. The following

formula has been used for this purpose:

R= A x Th.x Sp.Gr.

Where R= Gross reserves in million tonnes

A=Area in sq.km.

Th.= Thickness in meter

Sp. gr.= Specific gravity

As stated earlier, a 10% deduction from the gross reserves has been made to

arrive at the net in situ ‘proved’ reserves available in the block.


. . JOB NO.-515126 Chapter 4 / 74 of 81

METHODOLOGY OF OVERBURDEN ESTIMATION

The following procedure has been adopted for the estimation of overburden in

Amadand OC Block.

A total excavation (iso depth) plan has been prepared at 5m interval after

intersecting the surface contour with the floor contour of Seam LKIIB & LKII (the

lower most workable coal seam) to arrive at the total depth of excavation.

Isochores on I10 basis of the total coal of the seams considered for opencast

mining viz. Seams UKT, UKB,UK, L4,L3T, L3B, L3,MKT, MKB, MKC, LKI,

L1,LKIIT,LKIIB & LKII were intersected with each other to arrive at the

thickness of the total coal present. Isochores of the total coal, thus drawn, in the

respective area of occurrence of the seam(s), were intersected with the iso-

depth lines to arrive at the thickness and volume of total overburden in the

area. Different Coal: OB cut-off ratio lines were accordingly arrived at. The iso-

depth lines at 5m interval and the coal to OB cut-off ratio lines were transferred

onto the seam folio plans.

- The volume of overburden has been estimated by the volumetric method, i.e.

Volume (mm3) = Area (sq. km.) x thickness (m) considered.

- The volume of overburden has been estimated, depth wise and Coal: OB cut-

off ratio-wise.

- To arrive at stripping ratio, the total volume of overburden within the block area

has been divided by the corresponding coal reserves.

. . JOB NO.-515126 Chapter 4 / 75 of 81

DEPTH OF EXCAVATION

The maximum depth of excavation would be about 152.54m (CMAD-340) which

is found locally in borehole no. CMAD-340 up to the floor of Seam LKIIB due to

topographic high, surface RL of borehole CMAD-340 is 541.05m in the north

western part of the block. However, The coal reserves for all the coal seams viz.

UKT, UKB, UK, L4, L3T, L3B, L3, MKT, MKB, MKC, LKI, L1, LKIIT, LKIIB & LKII

are available within 170.00m average depth of excavation.

4.6.2 DESCRIPTION OF RESERVES

SUMMARY

A total of 160.57 Mt of proved reserves of coal have been estimated in Amadand

OC Block.

These includes 68.27 Mt (42.52%) superior grade coal of (A, B, C) grade and

90.30 Mt (57.48%) coal of inferior grade (D, E, F,G).

Out of the total Net Proved Reserves of 160.57 Mt of coal 6.19% is of ‘A’ Grade,

11.45% is of ‘B’ Grade and the bulk of the reserves, i.e. 24.87% falls under ‘C’

Grade, 23.40% is of ‘D’ Grade, 9.53% is of ‘E’ Grade, 11.53% is of ‘F’ Grade

and 13.03% in ‘G’ Grade. The quarriable reserves falling in the total proved

category are within 170.00m depth. Since the reserves are to be extracted by

opencast method, all the coal seams reserves have been assessed for coal

seams having thickness more than 0.50m (>0.50m), as desired by mine

planners.

fairly accurate within the limits of available data. A few boreholes along

proposed entry alignment are recommended to ascertain the point of disposition

of the coal seams and incrops.

2. Although not a single fault has been delineated in the block, but possibility of

some minor slips of small magnitude may not be ruled out.

3. Though the incrops have been proved on the basis of boreholes drilled, few

boreholes may be taken up, if suggested by the Planners in view of the

variable/rolling nature of the dips.

CHAPTER - V

MINE BOUNDARY, RESERVES AND MINE LIFE

5.1 INTRODUCTION

The Amadand Opencast Block is located in the eastern part of south

Sohagpur Coalfield and is flanked by working mines of Hasdeo and Jamuna

& Kotma areas of SECL to the east and west respectively.



submitted to SECL in August 2003 and approved in Sept 2003. During

preparation of Amadand OC (1.15 Mty) report, lower seams e.g. MK (Top)

and MK (Bottom) and LK-II were also considered for extraction by opencast

method. But, due to high stripping ratio, the quarriability of lower seam were

not feasible for departmental option. So seams below UK seam were not

considered in the 1.15 Mty PR.

Latter on, decisions was taken to extract coal from bottom seams.

Accordingly, Revised Geological Report have been prepared, considering

workable coal seams upto bottom most LK-II seam which has not taken into

account for opencast mining earlier. In the area under consideration seams,

L-6, L-5, UK (Top), UK (Bottom), UK, L-4, L-3(Top), L-3 (Bottom), L-3, MK

(Top), MK (Bottom), MKC, L-2, LK-I, L-1, LK-II (Top), LK-II (Bottom) & LK-II

have encountered in descending order.

The present report is formulated considering all the seams upto bottom

most LK-II seam for mining with outsourcing option.


. . JOB NO.-515126 Chapter 5 / 2 of 5

5.2 PIT FORMULATION STRATEGY

It is proposed to extract all the seams UK (Top), UK (Bottom), UK, L-4, L-

3(Top), L-3 (Bottom), L-3, MK (Top), MK (Bottom), MKC, L-2, LK-I, L-1, LK-

II (Top), LK-II (Bottom) & LK-II as they can be mined techno-economically

by opencast method. Quarry floor has been proposed on the floor of Seam-

LK-II. Access trench & Haul Road is proposed to touch seam LK-II at floor

RL of 420m. Haul roads have been planned at a maximum gradient of 1 in

16, the width of the haul road has been kept as 30 m for two way dumpers

movement.

This PR has been formulated mainly considering the following details:-

1. Increased demand of superior grade coal from CIC Coalfields.

2. Sufficient mineable reserves

3. Workable strike and dip length

5.3 MINE BOUNDARIES

The quarriable area for the opencast mining is shown on Plate No.3 &

Figure-5.1. One quarry on floor of Seam LK-II has been planned. The

boundary of quarry has been fixed as follows: -

North : Incrop of Upper Kotma Seam.


(more than 20).

South : Incrop of Upper Kotma Seam.



East : A line keeping 100 m barrier from boundary of Amadand

Village.

Reason-. The major state highway Pendra to Manendragarh

is passing along the middle of the Amadand Village. Two UG

mines namely, Amadand UG & Bartarai UG are situated on


. . JOB NO.-515126 Chapter 5 / 3 of 5

other side of the Pendra-Manendragarh state highway road

and area of these mines are not included within quarry

boundary of this 4.0 Mty RPR Report.

West : Incrop of Upper Kotma Seam


(more than 20).

Khodri Block has not been included in the proposed mine area. The

incrop of coal seams also exists in the northern side of Khodri Block.

Thus, Khodri Block can be extracted from the northern side of the block as

a separate mine.

5.4 MINEABLE RESERVES

As on 01.04.2015, the total mineable reserves within the quarries have


Mcum. The already extracted coal & OB removal has been deducted to

get the balance remaining coal & OB quantity. While, calculating mineable

reserves, a geological loss of 10% and a mining loss of 10% have been

considered. The estimation of mineable reserves is based on a minimum

mineable thickness of 0.5 m. The mineable reserves have been estimated

by iso-chore method from the seam extent plan of individual seams.

Similarly, OB has been estimated based on iso-parting and Top OB plan.

The plan showing seam extent of individual seams under consideration

are given at Plate No. 6 to 16. The top OB and the iso-parting plan

between seams under consideration are given at Plate No. 17 to 27.

5.5 TARGET OUTPUT & MINE LIFE


removal is of 52.54 Mty.


. . JOB NO.-515126 Chapter 5 / 4 of 5

Mine Life The mine life for nominal production is 19 years. The break-up is as under:




Total period - 19 years

5.6 FUTURE EXPANSION POTENTIAL It is proposed to extract upto the bottom most seam LK-II of the area.

Thus, mine does not have the scope to expand further in vertical direction.

In northern side, Khodri Block has not been included in the proposed mine

area. There is high stripping ratio zone(more than 20) between present

quarry boundary and Khodri block boundary. The incrop of coal seams

also exists in the northern side of Khodri Block. Thus, Khodri Block can be

extracted from the northern side of the block as a separate mine. In

western and southern side, beyond UK seam incrop, the stripping ratio

is high (more than 20). Thus, mine does not have the scope to expand

further under the present condition to north, south and west directions.

In eastern side, the quarry boundary fixed along a line keeping 100 m

barrier from boundary of Amadand Village. The state highway Pendra to

Manendragarh is passing along the middle of the Amadand Village. Two

UG mines namely, Amadand UG & Bartarai UG are situated on other side

of the Pendra-Manendragarh state highway road and area of these mines

are not included within quarry boundary of this 4.0 Mty RPR Report. In

future, if diversion of major state highway Pendra to Manendragarh can be

undertaken, decisions taken to extract UG property by opencast method

and shifting of Amadand village can be undertaken, in that case the

Amadand OC can be expanded in the east direction. Quarry planning and

dump plan has been proposed accordingly such that quarry can be

expanded in east directions in future.

CHAPTER-VI

METHOD OF MINING

6.1 GENERAL The PR has been formulated to win coal by Surface Miner with FEL and

coal body trucks & OB by Shovel Dumper combination.

In Outsourcing Option both winning of coal and extraction of OBR will be

done through outsourced HEMM. Transport of coal from face to railway

siding will be done by inpit belt conveyor & surface belt conveyor.

It is proposed that mine will be operated for 330 days in a year. In a day,

there will be 3 shifts and each shift is of 8 hours.

6.2 GEO-MINING CHARACTERISTICS

6.2.1 Seam Gradient - Variation, average gradient of quarry floor 1 in 30.

6.2.2 Geological Disturbances -

Only one normal fault F1F1, trending E-W and having a maximum throw of

80m, have been deciphered in the area at the northern boundary of block.

Within mine area no fault exists. However, the occurrence of faults of

small lesser magnitude cannot be entirely ruled out in the area.

6.2.3 Presence of In-seam band seam-wise The in-seam of all the seams is composed mainly of carbshale, shale,

sandy shale and sandstone.

6.2.4 Details of sequence of coal seam and parting

The sequence of coal seams with their thickness and parting range,

average grade & UHV range, Mineable coal and volume of OB within the

proposed mine area are as shown in table below:-

.CHOICE OF TECHNOLOGY

Surface miner has been proposed for extraction of coal. The salient

feature of the mining system is as follows: -

(i) Height & width of the benches in OB will depend upon the size

of the leased equipment. However, for Surface Miner height

restriction is not there. The provision of Coal Mine Regulation

and related circulars shall be strictly followed for designing

bench parameters in coal and OB.

(ii) Dump bench height - 30m (Internal dump has 7 benches and

total dump height 230 m from quarry floor & 90m from surface,

External dump height is 120m from surface).

(iii) Bench Slope

Coal / OB - 700

Spoil - 370


. . JOB NO.-515126 Chapter 6 / 6 of 9

Considering the average mine floor gradient of about 1 in 30, the coal

benches are proposed parallel to seam floor and self-draining. The mining

system is shown at Plate No. 6.

DRILLING & BLASTING

Pattern for drilling of blast holes will depend upon the height of the bench

and may design as follows: -

Height of Bench = H

Burden (B) ~ H/2

Spacing (S) ~ B*1.25

The suggested drilling pattern is for average mining conditions. These

may be suitably modified during actual mining operations as per the site

conditions.

HAUL ROAD

Haul roads have been planned at a maximum gradient of 1 in 16, the

width of the haul road has been kept as 30 m for two way dumpers

transport. Two batter road of 50m width will be maintained along UK seam

& MK seam for laying side road and inpit belt conveyor. (details given in

chapter 11)



coal body trucks & OB by Shovel Dumper combination.

In Outsourcing Option both winning of coal and extraction of OBR will be

done through outsourced HEMM. Few auxiliary HEMM has been given for

mine development and reclamation related work. Transport of coal from

face to railway siding will be done by inpit belt conveyor & surface belt

conveyor. To handle the larger OB quantity optimum no. of equipment with

required capacity is proposed be used. Minimum 10 cum Shovels with


. . JOB NO.-515126 Chapter 6 / 7 of 9

100T rear dumpers will be used for OBR by outsourcing agency. For thin

partings, smaller backhoe may be used.

As depth of OB increases the annual OB removal will also increased. To

handle the larger OB quantity optimum no. of equipment with required

capacity is proposed be used. Due to flexibility of operation, Shovel-

Dumper combination will be suitable for OB removal for working multiple

seams and partings.

The property is free from any major geological disturbances. Average

gradient of quarry floor is 1 in 30. The average strike length of the quarry

is 3.0 km. Thus, sufficient face length will be available for optimum

efficiency of surface miner.


Bottom. Both of the splits have varying thickness from 0.7 m to 1.50m.

Above LK-2 Seam, Seam L-1 exists having seam thickness 0.70m to

0.90m. Parting thickness between Seam LK-2 and L-1 varies 6 m to 18 m.

Thus, dragline horizon changing will be required for operation of dragline

and dragline productivity will be less. Besides, the bottom coal bench may

be diluted as low thickness coal seam may be mixed with OB during

dragline operation. Considering multi-seam working and wide variation of

parting OB, dragline has not been proposed in this Project Report.

6.6 MINING SYSTEM & SYSTEM PARAMETERS

Surface miner has been proposed for extraction of coal.

The salient features of mining system are as follows:-

i) Height of bench in OB will depend on the size of equipment.

Coal bench height will depend on the thickness of the coal seams.

The provision of coal mine regulations and related circulars shall be

strictly followed for designing bench parameters in coal and OB.

ii) Average Seam gradient – 1 in 30.

iii) Total dump height – Internal dump height is 230 m from quarry floor

but it will be 90m from surface. External dump height is 120m from

surface.


. . JOB NO.-515126 Chapter 6 / 8 of 9

iv) Bench slope –

Coal/OB - 70 degree

Spoil - 37 degree

Keeping the geo-mining characteristics of the deposit, in view, optimum

number of equipment with optimum capacity is proposed be used.

7.2 MINING STRATEGY / MINING SEQUENCE


1.15Mty and it is already extracting coal from UK seam.

It is proposed to expose MK seam in the 2nd year of mine operation by

grading properly the access trench and making its width 30 m wide and

gradient at 1 in 16. Then sufficient area to be exposed in the MK seam

floor. In the 3rd year of mine operation, the access trench is to be graded

at 1 in 16 to touch the mine floor at LKII seam of about 405 m R.L.

The quarry floor is developed in such a manner so as to facilitate

the proper drainage of water towards the sump. This would also facilitate

extension of coal and OB bench for full development of mine. After

creation of sufficient decoaled area, internal backfilling of OB will be

started in the 5th year. The coal production will continue from the 1st year

of mine life and the target coal production of 4.00 Mty will be achieved in

the 5th year.


. . JOB NO.-515126 Chapter 7 / 2 of 8

Two batter road of 50m width will be maintained along eastern side

batter. One batter road along floor of UK seam will be used to place inpit

belt conveyor to carry coal from UK & L4 seam as thown in plate 3. Other

batter road along floor of MK seam will be used to place inpit belt

conveyor to carry coal from MK, L3 & LK1 seam. One another inclined

inpit belt conveyor will be placed upto floor of LKII seam to carry coal from

LKII & L1 seam. Finally, through inclined belt conveyor all the coal will be

transported to surface as shown in the plate-3. From pit top coal will be

transported to upcoming Amadand siding through surface belt conveyor.

.(details given in chapter 11)

For reducing the external dump area and healthy operation of mine, 2

plans i.e. final stage of mine excavation and final dump plan showing

backfilling, Plate No. 3 & 4 are enclosed. The life of mine will be 21 years.

7.3 DUMPING STRATEGY In the initial years i.e. upto 4th year, entire OB will go to the external

dumps. For project implementation and aquision of land for external

dump may take 3 to 4 years. During this period about 20 Mcum OB

will be dumped internally. Provision of rehandling of this internal dump

to external dump site has been considered in the project costing.

Internal dumping will start from the 5th year onwards. The parting OB in

case of older seams may be transported partly through central haul road,

while mining in the multi seam zone.


separately. The spoil dump benches in the internally backfilled OB will be

in the form of benches. With the sufficient advance of coal production

bench, the backfilled OB will be leveled with dozer..


. . JOB NO.-515126 Chapter 7 / 3 of 8

Dumper/Tipper will transport soil/alluvium OB from the top OB bench and

will dump the soil directly on the leveled backfilled OB. The barrier

distance between internal dump and coal production bench will be 80 m to

have smooth functioning of machineries.

The slope stability study should be done. According to study report, the

dump design like dump bench height, total dump height & slope etc.

should be modified to avoid dump failure. In addition to that proper

precautions should be taken to avoid sliding of internal OB bench.

238.02 Mcum OB will be externally dumped outside quarry area from 1st

year to 10th year for which 356.50 Ha land will be required.

The northern boundary of Amadand OC block is along the Fault F1-F1

having throw of 20m to 80m. On the other side of Fault F1-F1 Khodri Block

exists where UK seam occurs at a minimum depth of about 21m. So

external dump has not proposed in the Khodri Block.

External dump has been made near southern boundary as shown in Plate

No.4. The break-up of OB quantity to be accommodated in various dumps

is as follows:-

Dump OB accommodated in Mcum 1. Internal dump 526.38 2. External dump outside Quarry area 238.02

Top soil will be removed and stored separately. This soil will be directly

spread over the leveled graded backfilled spoil for reclamation of the

quarried out land. Possibility of external dump within quarry boundary and

rehandling back into the quarry has been examined. Considering the high

quantity of external OB placing of external dump within quarry boundary

will not to be feasible. So placing of external dump proposed outside the

quarry area.


. . JOB NO.-515126 Chapter 7 / 4 of 8

Amadand OC can be expanded in the east direction. Quarry planning

and dump plan has been proposed accordingly such that quarry can be

expanded in east directions in future. At the end of quarry life, if required,

the void left will be filled to reduce the depth of void to 60m. Necessary

filling of the void will be done from mine closure cost. Initially the height of

internal dump is 90m from surface. After fifteenth year of mine life the

internal dump height will be kept upto surface level. Thus about 228.18 Ha

land will be levelled to surface level and can be utilized for agricultural

purposes.

30 m will be the height of individual bench.

30 m will be width of berm.

The slope stability study should be done. According to study report

necessary mitigative measure will be taken for the dump design like dump

bench height, total dump height & slope etc. In addition to that proper

precautions / observations should be taken to avoid sliding of internal and

external dump.

7.6 TOP SOIL MANAGEMENT

1.0 INTRODUCTION

The topsoil at Amadand block comprises of rich humus with minerals and

nutrients. Proper handling and management is necessary for future

vegetation growth in the mine reclaimed area. The thickness of the top soil

varies between 25 cm to 35 cm.

1.1 Objectives of the Soil Stripping management plan

The objectives of Top Soil Management are to:

Maintain a topsoil balance that achieves rehabilitation objectives during

the life of Mine.

Ensure effective topsoil removal techniques are employed to maximise

volumes of suitable topsoil removed and minimise wastage.

Maintain topsoil viability during stripping, spreading, and stockpiling,

through best practice technique and effective stockpile design and

treatment .

In accordance with the objective of providing sufficient stable soil material

for rehabilitation and to optimise soil recovery, the following strategies will

be adopted during the mining operation at Mahan opencast mines.

1.2 Stripping Prior to the commencement of stripping, areas will be cleared of

vegetation. Soil stripping will be undertaken by dozers and hydraulic backhoe

excavators to maximise the preservation of the quality of the soil. The HEMM

operators and supervisors should be trained and made aware for the same. This

will ensure that all suitable topdressing material resources are salvaged and that

the quality of the stripped top dressing material is not reduced through

contamination with unsuitable soils. Care will be taken during stripping,


. . JOB NO.-515126 Chapter 7 / 6 of 8

stockpiling, and re-spreading to ensure that structural degradation of the soil is

avoided and that excessive compaction does not occur during stockpiling.

1.3 Stock piling

Where possible, topdressing material will be re-spread directly from

stripped areas onto areas being rehabilitated. Where this is not possible,

topdressing material will be stored in stockpiles.

Stock piles will be dumped at places where they would not be disturbed by

future mining. Sediment fences or other barriers can be used where

necessary to retain sediment.

The overall topography for the graded surface should be designed to

minimize the uncontrolled flow of runoff.

Dispersed sheet flow should be broken up by terraces or benches along

the slope that also follow topographic contours.

On a fine scale the ground surface can be roughened by the tracks of a

bulldozer perpendicular to the slope. Construction of stockpiles with a

“rough” surface condition will reduce erosion hazard, improve drainage

and promote revegetation.

1.4 Stockpile preservation

Stockpiling topsoil may result in disruption & loss of beneficial soil

microorganisms and nutritional values, hence needs the following amendments

during preservation:-

1) Re-vegetation of the stockpile will be done as scheduled below to protect the

soil from erosion, discourage weeds and maintain active populations of beneficial

soil microbes.

Temporary Seeding- To protect topsoil stockpiles by temporarily

seeding as soon as possible, within 30 days after the formation of

the stockpile.


. . JOB NO.-515126 Chapter 7 / 7 of 8

Permanent Vegetation- If stockpiles will not be used within 12

months they will be stabilized with permanent vegetation to control

erosion and weeds. Likely grass species for revegetating top soil

stock piles are green panic, Japanese millet (spring sowing), Oats

(winter sowing), Dryland Lucerne, Seaton park sub-clover.

Topsoil can be mixed with organic material or manufactured soil

amendments to improve the growing capability.

2) To the extent practicable, above ground vegetation, including tree litter

should be mixed or otherwise incorporated into the topsoil.

3) Soil amendments: Soil amendments should be applied before seeding or

planting. Common soil amendments used are biosolids, compost, manure, lime

and coal combustion byproducts.

Prior to the placement, the top 0.30 cm of stockpile material should be

mixed with the remainder of stockpile to ensure that living organisms are

distributed throughout the topsoil material at the time of final placement. In case,

the material has been stockpiled for over nine month period, use of

microorganisms inoculates may be necessary to re-establish microorganisms in

the topsoil material. The quantity should be 200 ml for one Heactare area in case

of Azatobactor and Rhizobium.

1.5 Site Preparation

Before spreading topsoil, establish erosion and sedimentation control

structures such as diversions, berms, dikes, waterways and sediment

basins.

Adjust grades and elevations for receipt of topsoil.

Roughening - Immediately prior to spreading the topsoil, loosen the

subgrade to ensure bonding of the topsoil and subsoil.


. . JOB NO.-515126 Chapter 7 / 8 of 8

Soil horizons will be replaced in the same order that they were removed.

Top soil will be uniformly distributed to pre-mining thickness. Topsoil will

not be spread while it is frozen or muddy .

The topsoil will be compacted to ensure good contact with the underlying

soil, but excessive compaction will be avoided, as it increases runoff and

inhibits seed germination. Light compaction with roller will be done where

turf is to be established.

On slopes and areas that will not be mowed, the surface will be left rough

after spreading topsoil.

1.6 Monitoring

Specific team / manpower is to be deployed for this most important step of

topsoil management. The team will monitor the area and quantum of top soil

management with the authorities of mine on quarterly basis and regularly monitor

the given points of significant importance:

Monitoring Erosion Control: This step is necessary during stock

piling as well as reclamation stage of topsoil management. Take corrective

measure in areas showing evidence of erosion, sedimentation or slope

failure. This is a serious problem, because erosion causes fertile farmland

to lose nutrients and water retention ability.

Regular monitoring of top soil management should be done until

vegetation is demonstrated to be successfully established.

Reseeding: Take appropriate measures to address evidence of

invasive species or poorly established vegetation. Reseeding should be

done, if germination is not uniform or poor.

CHAPTER - VIII

MINING SCHEDULE & EQUIPMENT PHASING

8.1 DESIGN CRITERIA

Transport of coal from face to railway siding will be done by inpit belt conveyor

& surface belt conveyor. The mine has been planned for 330 days with 3 shifts

working per day. Duration of shift hours will be eight.

Excavation category assumed

i) Coal - - III

ii) Alluvial OB - Cat.I/II : Assumed

iii) Hard OB - 50% cat.III + 50% cat.IV Insitu volume weight t/cum i) Coal - 1.52 t/cum ii) Overburden - 2.40 t / cum

8.2 ANNUAL PRODUCTIVITY OF HEMM

The PR has been formulated to win coal by Surface Miner & OB by Shovel

Dumper combination. For OB removal year wise lead has been estimated and

based on that average lead for OB removal is estimated to 3.0 Km.

Transport of coal from face to railway siding will be done by inpit belt

conveyor & surface belt conveyor. The Annual productivity of outsourced

HEMM will depends on the size of deployed HEMM.


The PR has been formulated to win coal by Surface Miner with FEL and coal

body trucks/dumpers & OB by Shovel Dumper combination. In Outsourcing

Option both winning of coal and extraction of OBR will be done through

outsourced HEMM. Due to flexibility of operation, Shovel-Dumper combination

will be suitable for OB removal for working multiple seams and partings. As

coal production increased, the annual OB removal will also increased. To

handle the larger OB quantity optimum no. of equipment with required capacity

is proposed be used. Minimum 10 cum Shovels with 100T rear dumpers will be


. . JOB NO.-515126 Chapter 8 / 2 of 6

used for OBR by outsourcing agency. For thin partings, smaller backhoe may

be used.

The property is free from any major geological disturbances. Average gradient

of quarry floor is 1 in 30. The average strike length of the quarry is 3.0 km.

Thus, sufficient face length will be available for optimum efficiency of surface

miner.


Bottom. Both of the splits have varying thickness from 0.7 m to 1.50m. Above

LK-2 Seam, Seam L-1 exists having seam thickness 0.70m to 0.90m. Parting

thickness between Seam LK-2 and L-1 varies 6 m to 18 m. Thus, dragline

horizon changing will be required for operation of dragline and dragline

productivity will be less. Besides, the bottom coal bench may be diluted as low

thickness coal seam may be mixed with OB during dragline operation. So

dragline has not been proposed in this Project Report.

8.4 EXISTING HEMM POPULATION

In Outsourcing Option both winning of coal and extraction of OBR will be done

through outsourced HEMM. Few auxiliary HEMM has been proposed for mine

development and reclamation related work. In outsourcing option, few existing

HEMM will be used as auxiliary HEMM for mine development and reclamation

related work and rest of HEMM will be transferred elsewhere.

8.5 DRILLING & BLASTING

OB will be loosened by drilling and blasting to facilitate their excavation. The

actual pattern for drilling and blasting will be decided after field trials. For

secondary blasting 10% of additional explosives will be required for OB. The

drilling will be done carefully to keep at least 1.0m to 1.5m OB parting above

coal seam to reduce contamination of coal with fragmented OB. Whenever

required Ripper will be used reduce contamination of coal with fragmented OB.


. . JOB NO.-515126 Chapter 8 / 3 of 6

SMS explosives should be used wherever possible. The pattern for drilling of

blast holes will depend upon the height of the bench and may be designed as

follows: -

Height of bench = H

Burden (B) - H/2

Spacing (S) - B*1.25

The suggested drilling pattern is for average mining conditions. These may

suitably be modified during actual mining operations as per the site conditions.

The explosives consumption has been envisaged as 0.30 - 0.35 kg/cum of

excavation.

The ground vibration due to blasting can be controlled by:-

i) Optimising the amount of explosives charged per delay,

ii) Optimising spacing and burden of blast holes,

iii) Optimising the amount of explosives charged per blast,

iv) Proper strata movement during blast by using suitable initiating sequence.

Since above parameters are site specific, the exact blasting pattern will be

designed by conducting field trials.

8.6 CALENDAR PROGRAMME OF EXCAVATION


removal is of 52.54 Mty. The total mineable reserves within the quarries have

been estimated as 70.46 Mt with a corresponding OB volume of 764.40 Mcum.

While, calculating mineable reserves, a geological loss of 10% and a mining

loss of 10% have been considered.




Total period - 19 years Considering the average width of quarry and annual advance of quarry floor,

the calendar programme has been prepared and given in the following table: -

CHAPTER - IX

COAL QUALITY 9.1 INTRODUCTION

On the basis of moisture and ash percentage different litho units are

defined as under: -

Coal : Ash + Moisture upto 40%. Shaly Coal : Ash + Moisture from 40% to 55%. Carbonaceous shale/

combustible dirt band : Ash + Moisture from 55% to 75%. Obvious dirt bands : Ash + Moisture more than 75%.

Initially, the band by band analysis of the coal cores were obtained and

subsequently special tests and the proximate analysis at 60% RH and

400C were advised for Bcs, I30, I10, I100 and Ip basis which are defined as

under: -

Bcs Sample: only coal and shaly coal. I30 Sample: including combustible bands upto a thickness of 30cm. This

type of analysis has been asked only for assessing under ground

reserves. Dirt bands upto 5 cm irrespective of lithology have been

included in the seam for quality assessment. Carbonaceous shale bands

having thickness more than 30cm have been excluded from the seam

thickness.

I10 Sample: including both combustible and non-combustible bands upto

0.10m thickness. This analysis has been carried out for the seams having

quarriable potentiality.

I100 Sample : 'Bcs' sample + carbonaceous shale (ash + moisture upto

75%) bands upto 1m in thickness + grey shale (ash + moisture >75%)

bands upto 1m in thickness and excluding all other obvious bands such as

sandy shale, shaly sandstone, sandstone etc. irrespective of their

thickness.

Ip Sample: I100 Sample + carbonaceous and grey shale bands irrespective

of their thickness and excluding all other obvious bands as in I100 Sample.

CHAPTER –X

WATER MANAGEMENT (PUMPING AND DRAINAGE)

10.1 GENERAL

The general surface topography in the project is such that that surface

drainage is not likely to pose any major problems as no major nallah do

not traverse quarriable area. The area drainage is by Kewai River and

Hasdeo River.

Garland drains will be provided around the mine to keep the runoff water

away from the quarry. Fresh drains will be made as mine advances. The

drains will be connected to the natural drainage of the area. The drains

will be cleaned periodically to avoid overflow of the same. Embankments

will be provided around the mine wherever necessary to protect the mine

from flooding.

Efforts will be made to lay the benches and haul roads in such a way that

water will gravitate towards the main sump located at the deep most point

available at the current workings. The slope of the floor of benches will

be made such a way that water flows down to the sump to keep the

benches dry.

10.2 SOURCE OF WATER In general the sources of water inside the quarry are as given below:- - Direct rainfall in the excavated area

- Inflow of water from back filled area due to rain fall on it

- Inflow of water from area beyond excavation due to rainfall on it

- Seepage of water from strata water/Ground water

10.2.1 Direct rain fall in excavated area:-


. . JOB NO.-515126 Chapter 10 / 2 of 10

The rain water falling directly in the excavated area will flow down and

collected in the sump. It is assumed that 90% of water falling in this area

will be collected in the sump.

10.2.2 Inflow from back filled area:-

A part of rainwater falling on the Internal dumping area will flow down into

the mine. As the internal dump will be relatively loose so run off

coefficient into the mine has been considered as 0.1.

10.2.3 Inflow from area beyond excavation:-

A part of the rain water falling in the area beyond excavation will find its

way into the mine. Garland drains will be provided around the mine to

arrest the outside water so it is assumed that 10% of rain falling in this

area will flow down into the mine and collected in the sump.

10.2.4 Seepage from strata: / Ground water

There will be some seepage from Strata/ Ground water. This seepage

during dry season say November-June is expected to be low. During

monsoon and post monsoon period i.e. July-October the seepage will be

more. This is assumed as 10% of make of water in the mine.

10.3. MAKE OF WATER

10.4. SUMP

A sump will be provided at the deep most point of the mine. The sump will

be shifted as the mine advances. The layout of quarry provides suitable

gradient along the floor of the benches to facilitate self drainage of water

into the sump.

During heavy monsoon period, the work in the lower most benches may

be drowned as it will not be possible to pump out the entire make of water

in the wettest day. Therefore, it is proposed to drown a part of the lower

most bench which will work as a sump to accommodate the required

quantity of water which will be equivalent to the water accumulated due to

a rainfall of 172 mm in a day (at 10% probability).

Water from the sump will be pumped to surface which will pass through

sedimentation ponds before finally discharged into natural drainage

system. Sump will be cleaned periodically to avoid silting and mud

accumulation.

10.5.0 PUMPS

Nine numbers of main pumps each of 225lps, 160m head (along

with energy efficient motor) will be provided to meet the requirements up

to 21 years. Out of nine pumps six nos. will be working & three will be

standby. Some of the stages of the main pumps may be blanked when

they have to operate at shallow depths. This has been provided to reduce

the capital investment and utilize the pumps till the end of life. Provisions

have been made considering the peak demand which is occasional.

Further the pumps may be repaired and kept ready for use in rainy

season. Main pumps will be installed on pontoons. Provision of pontoons

for each main pump has been given in the estimate. After 10th year of

mine operation the depth of mine would be around 145m, so proper care

has to be taken to arrest water at upper seam. Thus stage pumping could

be avoided.


. . JOB NO.-515126 Chapter 10 / 9 of 10

Three nos. of Intermediate pump of 80 lps capacity, 100 m head,

110kw have also been provided to be used at low head. Two nos. of

diesel engine operated pump of 80lps capacity, 80m head has been

provided for operation in the initial period and then as standby for use in

case of emergency.

All the main pumps will be provided with pressure gauges on

delivery side and suction side for measuring the head developed so that

corrective action will be taken for operating the pump at the duty point.

The main pumps have been provided considering life of the mine.

The requirement of pumps has been shown for entire life of the mine;

however procurement shall be made as per requirement.

During heavy rainfall, overburden may be washed away from edges

of slopes and internal dumps, pumps capable of slurry handling will be

required. Pumping of clear water and slurry will be from upper and lower

part of sump respectively.

10.6 PIPING ERW pipes of 355.6mm outer diameter will be used for carrying the

discharge from 225lps capacity pumps. Similarly, ERW pipes of 273mm

outside diameter will be provided for carrying the discharge from 80lps

capacity main pump / diesel engine operated pumps and 219mm diameter

pipe will be provided for discharge from 38lps submersible pumps. Initially

the delivery pipes from each pumping stations are proposed to be taken

out through haul road and then through access trench and through side

batters of quarry at a later date. Provision for crossways are made on the

floor of the side batters for crossing the haul road so that dumper


. . JOB NO.-515126 Chapter 10 / 10 of 10

transportation is not affected. These pipes are evenly brought to the

surface from where water will be discharged to the sedimentation ponds

and then water will be discharged to natural drainage system. Provision

will be provided at pump house for connecting the delivery of the pumps to

at least two numbers of delivery ranges. Flow meters will be provided in

each 355.6mm diameter pipe for measuring the discharges.

10.7 CAPITAL INVESTMENT

The details of the proposed pumps, pipes and pipe fittings along

with estimated cost and brief specifications are shown in Appendix A.3.4.

CHAPTER-XV

SAFETY AND CONSERVATION

15.1 DEGREE OF GASSINESS

Since it is an opencast mine, degree of gassiness is of no relevance at

present.

15.2 SAFETY MEASURES AGAINST INUNDATION FROM RAIN WATER Adequate pumping capacity has been provided to deal with strata and

surface water. At the same time, diesel pump set has also been provided

to pump out water to the sump from temporary accumulated site.

15.3 DUST SUPPRESSION

Major source of dust in opencast mine operation have been identified in

haul roads due to traffic, due to spillage from dumpers and abrasion by

their wheels. Provision of adequate nos. of water sprinklers and adequate

lengh fixed type of water sprinkler have been made for spraying of water

on haul roads to prevent emission of dust. Haul roads and other heavy

duty roads likely to be negotiated by heavy vehicles and equipment have

been proposed to be metalled and coated to facilitate control of emission

of dust.

The drills to be engaged is to be equipped with dust arrester so that dust

emission is minimum. As the blasting is not continuous one and while

blasting, persons will be removed to the safe zone to reduce exposure to

dust created due to blasting. At siding, sufficient arrangements have been

provided to suppress coal dust at vulnerable points.

15.4 SLOPE STABILITY

SPOIL DUMP

The spoil will be stacked in the external and internal dump space at the

natural angle of repose to avoid the sliding of OB bench. The OB dump

will be terraced at the height of 30m. The barrier distance between internal

dump and coal production bench will be 100 m to have smooth functioning


. . JOB NO.-515126 Chapter 15 / 2 of 21

of machineries. The surface of OB dump will be leveled and graded.

Plantation will be made on the slope of OB heap to avoid the sliding of

spoil once OB heap becomes non-active.

The slope stability study should be done. According to study report the

dump design like dump bench height, berm width, total dump height &

slope etc. should be modified to avoid internal dump failure. In addition to

that proper precautions / observations should be taken to avoid sliding of

internal OB bench.

Dumping of soil and clayey material should be on the top of dump.

Final regrading of internal dumps is done in such a way that rain water is

drained outside the mine through drains and culverts. Proper monitoring

system shall be used for internal dump stabilization to avoid sliding of OB

dump.

15.5 HAUL ROAD MAINTENANCE

Haul road for dumper / tipper has been designed double lane with

shoulders on both side for movement of dumper and ancillary equipment.

Sharp turnings to be avoided to reduce the chance of any accident. The

access trench is graded to 6% slope. The ramp from one bench to another

bench is graded at 1 in 10 slopes.

15.6 BLASTING

For blasting crews, the blasting shelter has been provided. To reduce the

chance of fly rock and misfire, the optimum blasting pattern is to be

developed by trial. In view of the safety of the villages / public / mine

infrastructure against blasting hazards like fly rocks, ground vibrations etc.

proper safe distance has been kept from the mine working.


. . JOB NO.-515126 Chapter 15 / 3 of 21

However, when the mine working reaches near to the village

boundaries/mine infrastructure, controlled blasting will be adopted

alongwith other necessary precautions laid down by the DGMS. Misfire if

any, should be handled cautiously

15.7 CONSERVATION OF COAL

The coal recovery within panel excluding barriers is 60% and 80% to 85%

of extractable coal by Bord & Pillar Method and Longwall Method of

underground mining respectively. On the other hand, coal recovery is

almost 100% by opencast mining method. And so wastage of natural

resource is almost nil in opencast mining method.

The OB bench cut working will be kept sufficiently advanced in respect to

the coal bench working to avoid mixing of OB into the coal during blasting.

At the same time, the coal bench surface will be cleaned initially by dozer

and thereafter by surface miner to avoid dilution and contamination of

coal.

healthy vegetation. Main flora of the region includes plantation along the road side and

avenue plantation. The tree species observed in the area are, Albizia procera, Albizia

lebbek, Leucaena leucocephala, Delonix regia, Bauhinia variegate, Syzigium cumini, etc.

The major part of the study area lies under agriculture field and human settlements which

restrict the wildlife habitat significantly. Most of the mammalian species reported in the

study area are domesticated animals. There is neither any wildlife sensitive area nor any

corridor for the movement of wildlife is present in the study areas. Common Myna,

Kingfisher, Spotted dove and Pintail are some dominant bird species present in the study

area. Migratory movement of birds in the study area has not been reported. As far as the

reptile community was concerned, rat, snake, and house lizard are reported from the

study area.

Biodiversity conservation plan is developed with the aim to reduce the anthropogenic

pressure on natural resources due to accelerated pace of habitat change and natural

resource utilization. It needs a sustainable use and management of resources, identifying

and conserving critical habitats of wildlife and conservation of endangered and Schedule-

I species. Conservation plan also include the active participation of local communities.

The biodiversity management and conservation plan has been formulated considering

the wildlife (fauna and flora) profile of the region, customs, cultures & traditional rights of



locals, conservation significance of the area, and Biological Diversity Act (2002). Indian

Peafowl is present in study area having high conservation value.

16.1.5 Socio-economic Status

The project envisages 1443.01 Ha of land for quarry, infrastructure, residential

complex, safety zone and external dumps etc. This includes 702.379 Ha of land already

acquired for the existing Amadand OCP (1.15 Mty). Remaining 740.626 Ha land has to

be acquired for Amadand OC Expansion (1.15 to 4 Mty). The approximate number of

Project affected families likely to be rehabilitated is 1100. The families going to be affected

by acquisition of tenancy land / agricultural land are to be compensated economically and

jobs to the eligible land oustees / losers have to be provided as per M.P R and R Norms.

1.01 Vegetation Cover

Except the area such as used for quarry excavation, erection & development of plants, service & allied structures, colony, roads, diversions, culverts, etc, no other area is going to affected directly or indirectly by mining activities . Hence, impact on flora and fauna will not be of appreciable level.

1.02 Forests degradation

Forest areas are not going to be affected due to mining activities. Except the agricultural area used for quarry excavation, erection & development of plants, service & allied structures, colony, roads, drains, culverts, etc. Against this, 980.84 Ha of area will be generated by way of reclamation of dump areas, plantation in other available areas etc. By coal & OB transportation air pollution may affect photosynthesis and transpiration in plants by plugging their leaves pores. SO2 causes Necrosis disease in plants. Hence, no major impact on flora and fauna.

1.03 Ecological change

Being an opencast project, there is minor change expected in ecological parameters on which survival of flora and fauna depends directly or indirectly, and hence, expected impact on flora and fauna are not going to an appreciable level.

1.04 Hydro-geological aspects

Owing to opencast project, water level and draw down are likely to be affected to a nominal value; ground water and surface water on which the flora and fauna of the area directly or indirectly depend upon are not going to be affected to an appreciable level. After mine closure, the Mine void will act a stable water source for the flora & fauna.

16.3 Environment Management

16.3.1 Air Quality Management

Following air pollution control measures are practiced within the mining area and at

coal handling plants and railway siding.

1. Water spraying is done regularly on approach roads within the mining area to minimise

the dust generation.

2. Dust suppression has been proposed at mine, with an additional provision of Rs.155

Lakh for the purpose. This includes provision of 6.0 km long Fixed Water Spraying

Arrangement. For siding, an additional amount of Rs.10 lakh has been provided for mist

water spraying at the siding.

3. Adequate plantation will be done along the width of the haul road and other road to

minimize transport generated pollutants. The distance of haul road provided is 4.6 Km.

4. Coal transportation to pit-top will be done by belt conveyors. Amadand railway siding

is proposed near pit-top.

5. Exposed overburden dumps will be covered through an appropriate plantation.

6. The drills are equipped with dust arresting devices or wet drilling arrangement.

7. Optimum blast-hole geometry is being followed to reduce the dust during blasting.

8. Regular monitoring of ambient air quality of project area.

16.3.2 Water Quality Management

Management of surface water drainage: -

Garland drains will be made around the periphery of the quarry to drain out the

water of catchment area into the reservoir. In the workings, heavy duty pumps will be

deployed in rainy season which after passing through settling ponds will throw the

accumulated water from the working face into these garland drains, which in turn will be

delivered into the reservoir.

Mine Water Discharge



The water quantity at the floor of mine sump to be collected in different stages

has been assessed at 10% probability. The maximum mine sump capacity is 415545

Cu.m. The sump water will be pumped out and discharged to the settling tank where

suspended solids will get settled. The clear water after sedimentation & treatment will be

recycled for water sprinkling, plantation & agriculture purpose, ground water recharge &

for use by the local villagers etc. Collected water, after settling tank will also be discharged

into the surface drain which in turn will deliver into the reservoir. Workshop effluents will

be recycled through Oil and Grease trap and sedimentation tank.

Domestic Effluent Treatment: -

The sewerage disposal system for the colony exists with conventional septic tank

and a soak pit arrangement. As a part of Environmental Control Measures in township

the money to be spent for Sewerage Disposal in Colony is 29.63 lakhs and for Sewerage

Treatment Plant is 400 lakhs.

Water Conservation: -

The waste water recycling after due treatment will enable conservation of water.

The clear water after sedimentation & treatment will be reused for water sprinkling,

plantation & agriculture purpose, ground water recharge & for use by the local villagers

etc. Workshop effluents will be discharged and treated through Oil and Grease trap and

sedimentation tank.

Storage of conserved water in mine pits would be given due emphasis to provide

water round the year and the quality of water would be maintained. The balance left mined

out area of 250.41 Ha would be treated as water body after mine closure. The maximum

depth of the void is 130 m from ground level. The water body would serve as a

considerable source of water for the use of local population after final closure.

Control measures adopted against impact on ground water regime:-

i) The impact will be limited to a smaller distance and for a temporary period. The effected

habitation will be provided with suitable drinking water supply by sinking hand pumps in

the habitat.

ii) The entire mine industrial water demand, would be met from the treated mine

discharge. The wastage of water will be minimized.



iii) The surplus treated mine water will be discharge into the agricultural fields. Thereby,

the mine water will behave as constant source of recharge and improves the water levels

in the mine area. This will also become a resource for the local public and increase

agriculture output.

iv) So also, after cessation of mining, part of the quarry area will be reclaimed with highly

permeable OB material. The final void would be converted into a water reservoir. Thus,

in post-mining, the recharge and source potential in core zone will be much higher than

the existing.

v) With the increase in secondary porosity, a significant improvement in the rainfall

infiltration rate, close to the mine area can be anticipated.

16.3.3 Noise Management

The present noise levels are below the prescribed limits. If the impulsive noise

levels increase due to mining operation, suitable measures will be adopted to maintain

the noise level within permissible limits at working zone. The following measures are

adopted and will be continued:

1. Planting of rows of trees with thick foliage along roads and other noise generating

centers to act as acoustic barriers.

2. Isolating/enclosing the noisy machines/sources by using resilient mounting/altering

structures.

3. Routine maintenance schedules for HEMM and other machineries to eliminate noise

as far as possible.

4. Balanced and properly aligned conditioning of machines to reduce vibration.

5. Provision of ear muffs/ear plugs to workers subjected to noise level above

recommended limits.

6. Controlled blasting.

7. Regular monitoring of noise level of project area.

16.3.4 Flora and Fauna Management

The location of Amadand OCP does not have any importance as a holiday resort.

The surface to be disturbed by open cast mining operation does not contain any rare

variety of flora or fauna. As such, consequent to the opencast mining operation,



deterioration in quality of life or loss of amenity is not envisaged. Conservation plans of

schedule I & II animals, if any, will be prepared and implemented.

Compensatory afforestation and Strengthening of safety zone will be done.

The reclaimed and afforested internal dump and external dump of 841.31 Ha will

form one integral unit at the cessation of the mining activity. SECL will develop this

integrated area, as habitat for the fauna. The following steps will be taken for development

of habitat.

Reclamation of mine void:

In the core zone, after the cessation of mining activity a void will be created. This

void will be used as a water body. This will be graded to a gentle slope so that it acts as

a safe approach / access to the water body for the faunal species.

Through CSR activities in villages existing in the buffer zone, existing water

sources particularly the village tanks will be improved to provide drinking water to the

local community so that biotic pressure on water resources present in the forest areas

and used by fauna is gradually reduced.

Control of forest fire, fire in coal seam and coal stock:

Fire can destroy the entire habitats (micro and macro) and its life supporting

potential in a forest area. Fire does not spare fauna also. SECL will implement the

existing DGMS stipulated fire protection norms on coal seams and coal stock. This will

ensure that a congenial atmosphere is created and fire does not affect the fauna and flora

as well.

16.3.5 Land Resource Management

The project involves 715.02 Ha of land for the quarry area. This includes 70.46 Mt

(as on 01.04.2015) of mineable coal and 764.40 Mcum of OB. In the initial years i.e. upto

4th year, entire OB will go to the external dumps. Internal dumping will start from the 5th

year onwards. The parting OB in case of older seams may be transported through central

haul road, while mining in the multi seam zone.


separately. The spoil dump benches in the internally backfilled OB will be in the form of

benches. With the sufficient advance of coal production bench, the backfilled OB will be

leveled with dozer.



Dumper/Tipper will transport soil/alluvium OB from the top OB bench and will dump

the soil directly on the leveled backfilled OB. The barrier distance between internal dump

and coal production bench will be 70 m to have smooth functioning of machineries. The

slope stability study should be done. According to study report, the dump design like

dump bench height, total dump height & slope etc. should be modified to avoid dump

failure. In addition to that proper precautions should be taken to avoid sliding of internal

OB bench.

238.02 Mcum OB will be externally dumped outside quarry area from 1st year to

10th year for which 356.50 Ha land will be required.

External dump has been made near southern boundary. The break-up of OB

quantity to be accommodated in various dumps is as follows

Table 16.10 Dump Volume (Mcum)

A. External 238.02 B. Internal 526.38

Grand Total (A+B) 764.40

Present land use would be converted into internal dump, external dump, green

belt, built up area, surface infrastructure, final void/water body & other surface water body

etc. after the cessation of mining operation. Out of 715.02 Ha. of quarry area, plantation

would be done in 464.61 Ha. The dump surface would be maintained flat and top soil

would be sprayed over it as a part of final reclamation.

Plantation would be done on reclaimed internal dump, external dump, safety zone

and around the mine, infrastructure, etc. The no. of plantation is given as under.

a. Mine, infrastructure, colony etc. 58825 Nos, in 23.53 Ha.

16.4 Environment Management System

16.4.1 Monitoring Schedule

Environmental monitoring will be carried out following the monitoring schedule for

Air, Water, and Noise levels as per Standards of MOEF (Vide GSR 742 (E) dated

25.9.2000).

16.4.2 Plantation Monitoring

The project authority at field level will continuously monitor the growth and

survival/mortality rates of the plantations till the end of 3 years. Once trees attain desired

growth, no further monitoring will be required.

16.4.3 Action Plan for Land Reclamation and Plantation

The estimated life of the mine is 19 years. Maximum height of internal dump would

be 90 m from the ground level. The dump surface would be maintained flat and top soil

would be sprayed over it as a part of final reclamation. The maximum depth of quarry 150

m from the ground level. Approximate total no. of plants is estimated as 2452100 Nos. An

area of 250.41 Ha would be left as final void/water body after mine closure.

Year wise tentative programme of OB removal, dumping, plantation and the stage

dumping and reclamation programme are given below in table 16.18. Stage reclamation

plan thereof are shown in figures -18.2 for 5th year, 18.3 for 10th year, 18.4 for 15th year

and 18.5 for final stage reclamation plan respectively of Chapter - 18. X-section of final

MINE CLOSURE PLANNING

18.1 Closure Planning details of mine

Amadand OCP is an operating mine under Jamuna & Kotma Area, SECL and

comprises mostly (i.e. 1313.22 Ha, 91 %) of tenancy land. The expansion project area is

not involved with any industrial and mining activities for which require regular

environmental monitoring/audit. Environmental base line data for Amadand OC

Expansion, generated in the year of 2014, are utilized for preparation of this Chapter.

This data will enable to obtain a comprehensive idea of environmental quality in

and around the proposed project area in respect of air quality, water quality, noise level,

flora fauna, socio economic data etc. The project has been planned for a target capacity

of 4.0 Mty for 19 years life, to meet power grade coal. Beyond this life, the mine will be

closed if no further expansion towards the above adjoining blocks is considered. The

closure details are described below.

18.1.1 Mined out Land & proposed final land use;--

The proposed pre-mining and the tentative post mining land use plan has been

given below in table 18.1(a), (b) & 18.2 (a), (b).

18.5 Water Management: -

a) Physiography & Drainage

The Amadand Opencast Block has a gentle rolling topography with a general slope

in all directions from the central part of the area. The variation in surface elevation is from

530 m to 550.01m above MSL. The area has a radial drainage pattern while the major

part of the area is being drained by channels of Kewai River, a tributary to Son, the

channels in the north eastern part of the area discharge its water into Hasdeo river, a

tributary to Mahanadi. There are also a number of ponds in the area. The entire report

area including the villages and Pasture land is covered by cultivated field.

b) Water quality status of surface and ground water

c) Measures for control of water pollution

i) An amount of Rs 40 Lakh has been provided in the PR for Construction of Settling

tank for treatment of mine effluent.

ii) Adequate provision has been made for the construction of the workshop ETP (Oil

& grease trap) and other effluent generated in the industrial as well as residential

areas.

iii) Mine water after settlement will be used for industrial use like road watering, fire

fighting etc.



iv) Provision of Rs. 35 Lakh has been made for hydro-geological study.

v) Amount of 20 Lakhs has been provided in the PR for provision of 6 nos. of

Piezometers

vi) Provision of Rs.29.63 lakhs has been made for the colony sewage disposal.

vii) Money amounting to Rs.400 Lakh has been provided in the PR for construction of

Sewerage Treatment Plant.

viii)Environmental monitoring work will be continued as per the legal requirements and

will continue after subsequent three years post closure.

d) Water Conservation

The effluent generated in the workshop will be recycled for washing of vehicles. Steps

will be taken to maximise the reuse of effluent generated from the mine and colony.

Rainwater harvesting structure will be provided in the office/ colony at suitable place for

water conservation. The waste water recycling after due treatment for the purpose

mentioned above will enable conservation of water. Storage of conserved water in mine

pits will be given due emphasis to provide water round the year and quality of water will

be maintained before and after storage. An amount of 6.00 lakhs has been provided for

the rain water harvesting in the colony areas.

e) Water balance of the area (from EMP)

Except for coal mining, no major industrial development activity is located in the area.

As per CGWB, NCC Region, Raipur, the total annual replenishable ground water resource

in the Anuppur Development Block, Shahdol district (where Amadand UG proposed mine

exists), was assessed as 68.20 M.cum. It was also reported that the ground water

development in the block is as 1.99 % and falls within category "Safe". As such, the entire

Madhya Pradesh & Chhattisgarh States are covered under the category “Safe”. On

analysis, the net groundwater recharge and draft for the buffer zone were

estimated as 45.55 MCum and 33.73 MCum respectively. Thus, about 11.82

MCum groundwater recharge would be available annually in the area to meet any

future demand.



Figure-18.1

f) Acid mine drainage source, the existing practice of control and future plan

The existing mine water quality of Amadand & nearby mines are not acidic and it is

expected the acid mine drainage problem will not arise in Amadand OCP also. If however

acid mine drainage problem arises suitable measures will be taken as per standard.

g) Underground water/ quarry water management after closure (Specifying its

usage like domestic water supply, irrigation, and pisciculture or stabilizing the

ground water regime).

The final void (250.41 Ha) left after the completion of mining activity will act as a

water recharge basin for the area and may be utilized by the local community.

h) Water quality monitoring for three years after closure

The number of sampling stations shall be one with the quarterly sampling frequency

and two numbers ground water samples in core and buffer zone with quarterly frequency.

A monitoring schedule for Water levels will be as per Standards of MOEF (Vide

GSR 742 (E) dated 25.9.2000)

Water : For effluent & surface water the parameters to be monitored are pH, Chemical

Oxygen Demand, Total Suspended Solid, Oil & Grease at every fortnight and all

parameters once in a year. For drinking water, monitoring will be done as per

3. Water sprinkling arrangement will be provided at the transfer point of coal.

4. Water spraying will be done regularly on approach roads within the mining area

to minimise the dust generation.

5. Intensive plantation of adequate width all along the transportation road will be

raised to minimise transport generated pollutants.

6. Green belt fencing has been proposed for 12 km length in the safety zone.

7. Extensive plantation carried out in mine & other areas.

8. Biological reclamation & plantation over overburden dump has been

Proposed in an area of approximately 841.31 Ha. in a phased manner.

9. Exposed overburden dumps will be covered through an appropriate plantation

10. Optimum blast hole geometry will be followed to reduce the dust during blasting.

11. Regular monitoring of ambient air quality of project area.



18.7 Waste disposal

a) External OB dump & internal backfilling details (specifying the reclaimed

backfilled area, area of voids for water reservoir and also the OB dump area height

and volume) prior to closure of mine or during progressive mine closure

The project involves 715.02 Ha of land for the quarry area. This includes 70.46 Mt

(as on 01.04.2015) of mineable coal and 764.40 Mcum of OB. In the initial years i.e. upto

4th year, entire OB will go to the external dumps. Internal dumping will start from the 5th

year onwards. The parting OB in case of older seams may be transported through central

haul road, while mining in the multi seam zone.


separately. The spoil dump benches in the internally backfilled OB will be in the form of

benches. With the sufficient advance of coal production bench, the backfilled OB will be

leveled with dozer.

Dumper/Tipper will transport soil/alluvium OB from the top OB bench and will dump

the soil directly on the leveled backfilled OB. The barrier distance between internal dump

and coal production bench will be 70 m to have smooth functioning of machineries. The

slope stability study should be done. According to study report, the dump design like dump

bench height, total dump height & slope etc. should be modified to avoid dump failure. In

addition to that proper precautions should be taken to avoid sliding of internal OB bench.

238.02 Mcum OB will be externally dumped outside quarry area from 1st year to

10th year for which 356.50 Ha land will be required.

External dump has been made near southern boundary. The break-up of OB

quantity to be accommodated in various dumps is as follows

Table 18.6 Dump Volume (Mcum)

A. External 238.02 B. Internal 526.38 Grand Total (A+B) 764.40

Present land use would be converted into internal dump, external dump, green belt,

built up area, surface infrastructure, final void/water body & other surface water body etc.

after the cessation of mining operation. Out of 715.02 Ha. of quarry area, plantation would

be done in 464.61 Ha. There would be a final void/water body of 250.41 Ha left in the



project after mine closure The dump surface would be maintained flat and top soil would

be sprayed over it as a part of final reclamation.

Plantation would be done on reclaimed internal dump, external dump, safety zone

and around the mine, infrastructure, etc. The no. of plantation is given as under.

a. Mine, infrastructure, colony etc. 58825 Nos, in 23.53 Ha.

b. Internal Dump after backfilling: 1161525 No.s, in 464.61 Ha

c. External Dump: 941750 Nos in 376.70 Ha

d. Safety zone* : 290000 No.s in 116.00 Ha

Total Plantation = 2452100 Nos.

b) Stabilization of external O.B. dumps and backfilled area (Technical Reclamation)

Technical reclamation would involve breaking and levelling the top of OB dumps,

filling of gulleys and terracing etc. The maximum depth of the project will be 152.50 m. In

the initial years i.e. upto 4th year, entire OB will go to the external dumps. Internal dumping

will start from the 5th year onwards. The parting OB in case of older seams may be

transported through central haul road, while mining in the multi seam zone.

The height of each waste bench is restricted to only 30 m. The decoaled area after

simultaneous backfilling will be levelled by means of dozers keeping a mild slope of about

1 in 200 for surface water drainage for plantation and other purposes.

To the extent possible, top soil will be removed and stored separately. This soil

will be directly spread over the levelled graded external & backfilled OB for reclamation

Biological reclamation work will follow in next progressive year.

a) Top soil Preservation & Management

The objectives of Top Soil Management are to-

Maintain a topsoil balance that achieves rehabilitation objectives during the life

of mine.

Ensure effective topsoil removal techniques are employed to maximize volumes

of suitable topsoil removed and minimize wastage.

Maintain topsoil viability during stripping, spreading, and stockpiling, through

best practice techniques and effective stockpile design and treatment.

In accordance with the objective of providing sufficient stable soil material for

rehabilitation and to optimize soil recovery, the top soil management the stock

piling of topsoil will be practiced as follows:

i) Top soil and other materials removed shall be stock-piled only when it is

impractical to promptly redistribute such materials on re-graded areas.

ii) Stock-piled materials shall be selectively placed on a stable area, not disturbed,

and protected from wind and water erosion, unnecessary compaction, and

contaminants which lessen the capability of the materials to support vegetation

when redistributed.

iii) The stockpiled top soil is preserved by adding–up organic material, manure and

other similar amendments.

iv) Uniformly distribute topsoil to suitable thickness. If sufficient topsoil is available,

a minimum compacted depth of a half meter on 3:1 slopes and one meter on flatter

slopes is suggested.

v) Specific team / manpower are to be deployed for this most important step of

topsoil management. The team will monitor the area and quantum of top soil

management with the authorities of mine on quarterly basis and regularly monitor

the given points of significant importance.

vi) Organic or inorganic fertilizer should be applied periodically if vegetation growth

is poor.

vi) Regular monitoring of top soil management should be done until vegetation is

demonstrated to be successfully established.



b) Plantation on external & backfilled area, avenue and block plantation with

type of plantation i.e local/native species. Name the local species for

plantation.

Green belt on dumps:-

After technical reclamation of external & internal OB dumps and redistribution of top

soil over it, the dumps will be made biologically reclaimed. The above activities will be

carried out in a phased manner.

Green Belt around Mine: - In the directions where natural forest does not exist, there is need for creating green

belt of adequate width as an effective dust and sight curtain in the periphery of mining area,

residential areas/villages including those areas which are falling in the downwind direction.

There will be three tier plantations in the green belt area of 12 km length that shall act as

buffers and shock absorber against dusts, noise and stone flying. The trees in the green

belt will be wind firm, broad leaved and evergreen and of three different heights planted in

three tiers.

Haul Roads & other avenue Plantation: -

A green belt of adequate width on either side of the haul road will be raised and

the existing vegetation will be protected. The plants will be raised at spacing of 2.0x2.0

m. The roads available in the mine and other project areas will be provided with avenue

plantation as far as practicable.

c) Infrastructural Facilities (Nursery):-

A nursery is a pre-requisite for supply of seedlings of suitable species of right size

to the extent required. Rajya Van Vikas Nigam has already raised a nursery to grow

saplings and related activities in the administrative area of SECL.

Species for plantation.-

• Fruit bearing trees

– Jamun, Mango, Imli, Sitaphal, Bel, Ganga Imli, etc.

• Medicinal trees

– Neem, Karanj, Harra, Behara, Aonla, Arjun, Shikakai, Mahua, Kusum.

• Timber value trees

18.12 MINE CLOSURE COST

The mine closure cost will cover the various related activities for which a corpus

escrow account @ Rs. 6.0 lakh per Ha for Opencast mine of the project area shall be

opened with the coal controller organization. The above amount is as per the mine closure

guidelines issued in August 2009, which will be updated for the present financial year

based on the cost index value.

18.11.1 Mine Closure Cost for OC mine

As per the guidelines of the MoC, the cost of the mine closure is to be computed

on the basis of the project area involved in the project. In Amadand OCP total land area

involved is 1443.005 Ha. The updated cost of the mine closure as on March’15 is

estimated to be Rs. 8.15 lakh per hectare (considering the admissible escalation over Rs.

6.00 lakh per Ha as on August 2009).

Final mine closure cost @ Rs = W.P.I of March 2015 176.10 /W.P.I of Aug.09

129.60 x 6= Rs.8.15 Lakh/ Ha. for 1443.005 Ha = Rs.11760.491 lakhs.

The balance life of the mine is 19 years. Hence, the management of funds in the

Escrow Account would be as follows:

to mine closure (as per the mine closure guideline).

The progressive mine closure will deal the land reclamation as per the calendar plan of

project report given in table 18.4. The cost of progressive land reclamation is already part

of the project cost. Therefore, the escrow account for mine closure will deal only the final

mine closure.



18.12 Implementation Protocol

For implementing the mine closure activities, the following organisational structure has

been proposed:

Director (Tech.)

Environmental monitoring for three years after closure of mine will be carried out to

evaluate the environmental quality of the area. If need be, proper mitigation measures will

be taken up after evaluating the environmental quality. The funds for this have been

provided in the cost estimate. Before closure of the mine, Area GM will prepare survey

and disposal report and the same will be submitted to DGMS for acceptance.

will be carried out at the project site during the life of the project and at each stage of the

closure.

The mine authority has an ongoing responsibility for rehabilitation of its mine site to the

point where the site can be returned to the concerned authorities

The company should create organisation at mine, area and headquarter level to monitor

the operation of mine closure.

There will be an organisation / team of supervisory officers / staff and workman for

implementing and carrying out various activities of mine closure.

A team of employees will continue at the mine site even after the mine is closed, to see

that completion criteria are met or not.

The last phase of the closure may take 4 to 5 years of time even after production of coal

is stopped.

The mine authority will finally withdraw from the area after the implementation of closure

plan.

Existing Capital as on 01.04.2015 is 10882.52 Lakhs and Net block capital is 6009.91

Lakhs. Some existing HEMM will be transferred to other mine as in this report both coal

and OB removal is proposed to be done by outsourcing. As on 31.03.2015, Net block of

HEMM which are to be transferred from this project is Rs 3528.71 Lakhs. Net block

considered for project costing = Rs (6009.91-3528.71) Lakhs = 2481.20 Lakhs

21.1.2 Basis of price of P&M, Civil works & hiring rate

Price of P&M has been taken from the standard price list published by CMPDI, HQ on

May 2014. Prices have been updated upto July 2015 as per escalation rate given in the

price list.

The preparation of cost estimates for civil infrastructure is based on prevailing cost

index of the area in July 2015. The cost index value has been calculated from the

market rate of the area. Considering the prevailing rates of materials and labour in

Jamuna-Kotma Area, the cost index works out to 2926 w.r.t. 100 base in Delhi as on

1.10.1976.

21.1.3 Foreign Capital

No foreign capital investment has been envisaged.

21.1.4 Capital upto target year - Rs. 38943.20 Lakhs

Capital requirement beyond target year - Rs. 37117.88 Lakhs

Specific investment - Rs. 2173.60 tonne

Specific investment for P&M - Rs. 996.90 tonne

21.2 OPENING OF REVENUE ACCOUNT The norms for bringing coal projects into revenue account as decided in the meeting

held under the chairmanship of JS&FA on 9.6.04 are as follows:-

1) Revenue expenditure to be capitalized should be net of sales receipts of coal

produced during the construction period.

2) The period of construction has to be defined to determine the commercial readiness

of the project to yield on a sustainable basis.

3) In case of opencast projects, the volume of stripping of OB and in case of UG

projects, the completion of required development activities during the above period of

construction have to be clearly defined.

4) Based on the above, the capitalization of revenue expenses / opening of revenue

account will be decided.

Accordingly, a definition of the term ’commercial readiness of a project has been drafted

and based on this a norm for capitalization of revenue expense / opening of revenue

expenditure of a project has been suggested as under:-

A. Commercial Readiness: A project will be treated to have reached the stage of commercial readiness to yield

production on sustainable basis from the year when all the following criteria have been

achieved –

(i) 30% of the total volume of excavation (Coal and OB) envisaged in the target year.

(ii) The land required for the project upto target year has been acquired.


. . JOB NO.-515126 Chapter 21 / 3 of 9

(iii)Construction of CHP and railway siding have been completed or adequate

alternative arrangement for sizing and dispatch of coal have been commissioned for the

Project.

B. Capitalisation of Revenue Expenses based on commercial readiness:

For the preparation of Feasibility Reports, the revenue expenditure of a project can be

capitalized till the year the project achieves commercial readiness as per the plan

envisaged.

The capitalization of revenue expenditure, in no case, shall extend beyond the year the

Project achieves the status of commercial readiness.

The Amadand Opencast project is on going project with a target production of 1.15 Mty

and the project is already in operation. This RPR is being prepared to enhance the

production from 1.15Mty to 4.0 Mty.

Considering the on going project, the Revised Project Report would be brought

under revenue account w.e.f. the beginning of 1st year of operation. Thus the revenue

expenditure of the project has not been capitalized during the initial years.

21.3 REPLACEMENT CAPITAL

Year-wise phasing of replacement capital is given in Appendix-D.1 column No.3. 21.4 SOURCES OF FINANCE

The project will be financed completely by internal resources.

21.5 COMPLETION COST

As per the latest guidelines, the completion cost of a project will qualify all the following

conditions:

- Achievement of coal production capacity of 80% of the rated output.

- Completion of all major facilities and initial mine development work.

- Procurement of major and essential plant & machinery.

Completion cost of the project is estimated as Rs. 912.28 Crores.

21.14 CONCLUSION

In this report both coal and OB removal is proposed to be done by outsourcing.

In this outsourcing option, total capital investment works out to Rs. 869.44 Crores.

(Addl. Capital investment of Rs. 760.61Crs.). The project report for Amadand OC(1.15

Mty) may be treated as dovetailed with project report for Amadand OC (4.00 Mty) for the

purpose of implementation as all the required activities and financial provisions of

Amadand OC(1.15 Mty) have been included in Amadand OC (4.0 Mty) Report.

In this report recommendations of 310th meeting of CIL Board (held on 8-11-14)

regarding modification of cost provisioning in PR for CIL projects have been

incorporated.

The project is yielding an IRR of 13.55% at 85% level of production. As per the

guidelines, a Project is economically viable when it achieves more than 12% IRR at

85% level of Production. Since, this Project is having Internal Rate of Return more than

12% at 85% level of target production i.e. 13.55% the Outsourcing Option of this project

is economically viable project.

The outsourcing option of RPR for Amadand Opencast Project (4.00Mty) was

placed before SECL Board’s 236th meeting held at Raipur on dated 04.09.2015 for a

total capital of Rs 869.44 Crores and SECL Board directed to submit the same to CIL,

since capital provision in the RPR exceeds Rs 500 Crores.

CHAPTER - XXII

A CHAPTER ON OUTSOURCING 22.1 INTRODUCTION

Outsourcing has become increasingly attractive for many organizations in

recent past. Businesses irrespective of its size, skill, knowledge and

technology are finding outsourcing mechanism most befitting in terms of

cost reduction as well as quality improvement .With globalization and

removal of barriers, outsourcing has created new opportunities for

generation of employment. Today whether it is a canteen services or

security services or courier services or gardening, is no longer one man

providing service to one organization. These are just examples and we

can go on listing them but essentially they are contractor or organizations

which provide a specialized service at a competitive price. The service

itself is much better than what an entrepreneur if he engages workmen on

his roll would be able to provide. Further, the quality of the service is much

better and it leaves the entrepreneur to concentrate on its core activity.

Outsourcing will remain in the four front of every business executive mind

as a business strategy that will let their organization to create and sustain

business value in the competitive global market for reduced cost, focus on

core business processes, improve services, enhance skills, and increase

competitive advantages.

Growth in outsourcing is expanding to include not only IT functions, but

critical business processes, as well as evolving application areas like

enterprise resource planning and re-business initiatives. Successful

companies are incorporating outsourcing as a key strategy for growth and

differentiation. No longer considered merely a tactic for cutting costs and

been recommended by TSC on 31-07-2015 for a capital investment of Rs. 869.44 Crores to

put up before SECL Board for approval.

Meanwhile after the TSC meeting, new guideline issued by 317th CIL board held on 4th

July,2015 regarding cost provisioning in project report of CIL projects has been received. The
