2. INTRODUCTION OF THE PROJECT/ BACKGROUND INFORMATION
(i) Identification of project and project proponent.
Chhattisgarh State Power Generation Company Limited (CSPGCL) is proposing Gidhmuri & Paturia coal blocks opencast mining with capacity of 5.6 MTPA
at Hasdeo Arand Coalfield, Korba District, Chhattisgarh to meet requirement for the
thermal power plant of a capacity of 2 X 660 MW at Bhaiyathan in Chhattisgarh
State.
Chhattisgarh State is fortunate that it has immense possibilities of coal based
thermal power generation. At the national level one finds several States suffering
from serious power crisis. Looking to abundant availability of coal in the state,
1
Chhattisgarh would be developed as a 'Power Hub' of the nation from where power
would be exported to other needy States.
Chhattisgarh State Power Generation Company Limited (CSPGCL) is emerging as the
epicentre of “Power" of the nation it is constituted on 15th
November 2000. Ministry of Coal and Mines, Government of India has allotted Gidhmuri & Paturia coal blocks
to CSPGCL located in Hasdeo-Arand coalfield area on 13th
October 2015 (order no: 103/28/2015/NA) to meet the requirement of 5.6 MTPA coal for proposed coal based power plant at Bhaiyathan.
The Mining Plan (April, 2007) of Gidhmuri & Paturia coal blocks (Hasdeo Arand
Coalfield), (5.6 MTPA) has been approved by Ministry of Coal, Govt. of India vide its
letter No. 47011/1(22)/2002-CPAM/CA-1 Dtd 06-September-2007. The approval
conveyed under section 5(2) (b) of the Mines & Minerals (Development &
Regulation) Act, 1957.
(ii) Brief description of nature of the project.
The proposed Paturia Gidhmuri opencast mine of 5.6 MTPA capacity is a captive coal mine to supply the coal for proposed thermal power plant at Bhaiyathan, which will
fulfill the future power requirement of Chhattisgarh State and will accelerate the
economic development of the State.
The Gidhmuri & Paturia Block is in area of about 1751.92 ha and are situated in the western part of Hasdeo-Arand Coalfield. The total coal reserves by open cast coal
mining is 158.40 million tonnes.
(iii) Need for the project
The mineral wealth of a nation is an important feature in its economic progress, and mining in India has a vital role in the development. Chhattisgarh has a glorious
heritage in the field of natural resources, mines and minerals. The state is
geologically so endowed that it has become a veritable repository of minerals.
Detailed investigations were confined so far to major minerals only that are coal. For
the development of more and more coal based power plant and to cater the needs
of power plant emphasis is given on investigation of coal.
Search and exploration of coal in the State during last few years has resulted in the
discovery of several coal deposits in Hasdeo Arand coal field. These are large workable reserves and their mining has already been started. The State is in the
process of becoming power hub of the country because of abundant deposits of coal
have been reserved for power generation.
Electricity is the key for development. All sectors viz. industrial, agriculture and
social require electric power for their growth and development. There is a substantial gap between demand and availability of electricity in the nation. In the
direction to fulfil this gap, coal based Bhaiyathan power plant is being proposed to
setup at Chhattisgarh state. Proposed Paturia–Gidhmuri mine is an essential
component of the aforesaid project.
About 67% of the power plants in India are coal based. The proposed Paturia,
Gidhmuri opencast mine of 5.6 MTPA capacity which is a captive coal mine of
Chhattisgarh State Power Generation Company Limited (CSPGCL) will whole out the
coal to proposed thermal power plant at Bhaiyathan, which will fulfil the future power requirement of Chhattisgarh State and will bring the economic development
in the State.
2
(iv) Demand-Supply Gap
The development is directly proportional to the increase in demand of basic facilities
like water and electricity. Presently 1694.35 MW of gross electricity is available and
restricted demand of electricity as on date is around 1965 MW and unrestricted
demand is 2208 MW. Out of gross capacity, 1410.05 MW power is generated by
CSPGCL. The details are given in Table–1 below.

3.4 Size or magnitude of operation
Chhattisgarh State Power Generation Company Limited (CSPGCL) is
proposing Gidhmuri & Paturia coal blocks by opencast mining with capacity of 5.6
MTPA at Hasdeo Arand Coalfield, Korba District, Chhattisgarh to meet requirement
for the thermal power plant of capacity of 2 X 660 MW at Bhaiyathan in Chhattisgarh
State.
This output is prima facie considered technically feasible because of its favourable geo-mining conditions like:
Thickness of various seams; Their disposition & its splits; Comparatively long strike length; and Sufficient mineable coal reserves etc.
3.5 Project description with process details
3.5.1 Physiography
Mining of coal is carried out by opencast, which is approved by Ministry of Coal for Gidhmuri & Paturia block. Open cast mining is preferred where, there is no hard
cover or the extractable coal reserve is in economical stripping limits.
3.5.2 Regional Geology
Gidhmuri & Paturia blocks lie in western part of Hasdeo Arand coal field. Where the
coal blocks are broadly delineated by the Rehar river (known as Arand river) in the
east and Hasdeo river in the West thus the coal field has been named as Hasdeo Arand coal field.
Hasdeo-Arand Coalfield is bound by vast stretch of Talchir Precambrian formations in
the North-West is represented by gneisses in the East. Mand-Raigarh & Korba
coalfield in the west. Supra-Barakars (Kamthis) occur in the south eastern part of
the coalfield. Based on G.S.I report (1982-1985) geological formation of the Hasdeo-Arand Coalfield is given in Table-2.

3.5.3 Geo Mining Characteristics
Strike & Dip
Paturia
The general trend of the strike of the seams over larger part of the block is East-West to WNW-ESE. However, there is local variation in the strike of the central part
where it becomes NNE-SSW. The dip of the formation in general is 10 to 4
0 towards
south west.
Gidhmuri
The Gidhmuri block forms part of plunging anticline structure with its plunge axis in
NW-SE direction. However, this anticlinal structure has been dissected by fault. The
wide range of dip and strike vacation may be attached to the location of the block on
this anticline.
The general trend of the strike of the seams is East-West in the western and south western part. The strike swings to N-S in the eastern and southern part. The dip of
the formation in general is 20 to 5
0 easterly in the eastern, central and southern
part and almost southerly in the south western part.
3.5.4 Seam Description
Barakar formation occurs in Gidhmuri & Paturia blocks beneath the soil cover while
Talchir formation are not exposed they have been only intersected in some
boreholes.
Gidhmuri block has developed 5 coal seams viz I, II, III, IV & V seams in ascending
order Seam-I is a very thin seam (mostly <0.9 m) in entire Gidhmuri block and is
not suitable for mining. Seam II is thin seam (0.10 m-1.20 m) and lies with
substantial parting of around 60 m with seam III in Gidhmuri block. Seam III is most potential seam (7-8 m) in this block.
In Paturia block four coal seams have developed, seam-I, II, III, and IV is developed in ascending order. Seam-II occurs in split as well as composite seam.
The seam underlies seam-III (Bottom seam) with a parting ranging 13 to 21 m has
8
only U/G potentiality. Seam-III splits into three sections over the entire Paturia
block designated as III Top III Middle & III Bottom sections. For opencast
consideration two sections of III TOP have been considered as composite seam (III
TOP-1 + III TOP-2 with intervening parting which on western side in Paturia block.
The seam extractable coal reserves are given in Table-3.

Transportation of Coal
It is proposed that coal from the mine will be dispatched by rail/road. The proposed railway siding for this mine has to be provided by CSEB. Empty rake would be
brought near the loading point below Silo. Rake will remain attached to the pilot
engine during loading operation. After loading the wagons, the pilot will move
through M.G.R bulb to reach the terminal station or its destination without
decoupling of locomotive. Here provision has been made by rapid load out system to
load minimum six rakes per day by silos and bunker in combination with reclaim & loading conveyors. The formation level of loading point has been assumed as ground
level.
3.6 Raw materials required along with estimated quantity, likely source, marketing area of final product/s, Mode of transport of raw material and finished product.
No raw material is required as this is a mining activity. Only diesel would be
required for transportation of vehicles, operation of HEMM and generators in case of emergency. Coal from Mine after weighing the trucks will be unloaded at insitu
crusher to reduce the size less than 200 mm. From the crusher units the coal will be
transported to the coal surface storage bunker by conveyor system. From the
surface bunker, coal will be transported to Power station through road/railway. The
overburden will be removed using shovels/backhoes and will be transported with a
fleet of Rear discharging dumpers.

3.7 Resource optimization/ recycling and reuse envisaged in the project, if any,
should be given.
Resources like Explosives, Diesel Oil, Machinery, Land, Power and Water are fully optimized to minimize unnecessary losses during the process of excavation and
supply of coal to the customers. The production capacity from Mine will be 5.6
Million Tonnes per annum at peak requirement. The coal does not require
beneficiation. The resources which are used in the mining will be recycled by various
methods. Sludge generated from domestic wastewater treatment will be composted
and used as manure. Spent oil from transformers, will be sold to the authorized
vendors. The ground water pumped for safe mining will be used for drinking water. Mine sump water collected at settling pits shall be discharged from quarry through
pumps and used for dust suppression, mining activity, irrigation to surrounding
villages.
3.8 Availability of water its source, Energy/ power requirement and source
should be given.
3.8.1 Power
The proposed mine will get power from CSPDCL substation and power will be distributed by 33 KV line.
Electric power will be supplied for pumping and illumination for the opencast mine as the major equipment of Gidhmuri & Paturia. The power requirement for the mine will
be 80 MVA.
Standby DG Sets of adequate capacity. Fuel requirement will be about 172 KL/day of HSD.
3.8.2 Water Supply & Sewerage
It is proposed that requirement of potable water requirement is met from ground
water resources. For meeting the initial industrial water requirement also ground water resources may be utilized. After the mine starts production i.e. attains full
production capacity the mine inflow water will be recycled to meet industrial water
demand. Demand of potable water is proposed to be met by ground water source by
making bore wells and distributed through ground reservoir. Industrial water
demand is proposed to be met from bore wells. The water will be stored in ground
reservoir and distributed through overhead storage tanks located at suitable points.
Domestic and industrial effluent will be disposed of after suitable treatment in the effluent treatment plants (STP/ ETP) located in colony and industrial area.
3.9 Quantity of wastes to be generated and scheme for their Management/ disposal.
Solid waste:
Out of the total volume of OB estimated of 644.95 Mm3, only 25.65 Mcum is
proposed to be dumped externally while the remaining 619.30 Mcum of OB is proposed to be dumped internally. The maximum RL of all the dumps is +520m. Due to the fact that the seams are very gentle in gradient and overall geology amenable to internal dumping, external dumping requirement is very less (2.2% of total dumping needs). All the external dumps will be accommodated in non-forest zone.

Land requirement for Spoil Dumping
It may be observed that the amount of OBR to be dumped externally is very less
(2.2% of total OBR), thanks to the very gentle gradient of the seams and overall geology. The external dumps have been planned keeping in view the minimization of
lead and land requirement. External OB dumps have been planned in such a way
that there is no requirement of forest land for external dumps. Non Forest Land
required for external dumping for Quarry-1, 2, 3 & 4 is 101.26 ha.

4.3 Topography and drainage
The Gidhmuri & Paturia blocks cover an area of about 1751.92 Hectares in four
villages, namely Gidhmuri, Paturia, Madanpur and Uchlenga. The area exhibits a
land use pattern that mainly consists of forest and agricultural land. The proposed
site is covered with fairly dense forest. The topography and relief of the area is southeast and south-westward. The study area best represents as moist region. The
vegetation is fairly dense and occurs on Barakar rocks and reddish yellow loam soils.
Soil and topography vary together. It can be helpful to differentiate three subtypes
of topography, hilltops and plateaus, lower hill slopes, and valley bottom. There is
light shrub and weed growth under the forest canopy.
The maximum elevation above MSL in the block is 525 m in the mid of Paturia block,
and lowest is 459 m near Bamhni river in the north western part of Paturia block.
The general slope of the ground is from south to north in the Paturia block whereas it is north to south in the Gidhmuri block.
Hasdeo river is the most important river in the Gidhmuri & Paturia coal blocks area. All
the smaller natural channels like Dokka nalla, Bamhni nalla and Bisrar nalla, join the
Hasdeo river. Together these form the group representing the surface water resources in
the region. Dokka Nalla and Bisrar Nalla are passing through mid of property of quarry-
1. It is recommended to divert Dokka Nalla and Bisrar Nalla for safe mining operation
after detailed topographical study and drainage pattern of the
17
area. Catchment area on the north of quarry-3 is naturally draining into Bamhni
Nalla meeting into Hasdeo river. A garland drain is proposed to arrest the rainwater
entering into the mine. Eastern Boundary of quarry-1 has been kept at safe distance
of 40 m from western bank of Dokka Nalla.
4.4 Existing land use pattern, shortest distances from the periphery of the
project to periphery of the forests, water bodies.
The Gidhmuri & Paturia blocks cover an area of about 1751.92 Hectares in four
villages, namely Gidhmuri, Paturia, Madanpur and Uchlenga. The area exhibits a land
use pattern that mainly consists of forest and agricultural land. The proposed site is
covered with fairly dense forest. The topography and relief of the area is southeast
and south westward. The study area best represents as moist region. The vegetation
is fairly dense and occurs on Barakar rocks and reddish yellow loam soils. Soil and

5. PLANNING BRIEF
5.1 Mining Method
The Mining method is shovel /Backhoe will be deployed in the advancing benches.
The excavated overburden will be spread back by using dumpers in the mined out area. After Top soil spread, the backfilled area will be biologically reclaimed and
afforested to restore to pre-mining condition.
5.2 Design Criteria
Sequential mining suited for achieving the objective of placing maximum possible
OB in the internal dumps. Thus external dump quantities from this pit will be
minimized.
The following design criteria have been considered for waste dumps.
1) Separate spoil dumps are proposed for Topsoil and hard OB
2) Maximum height of topsoil dump is to be 10 meters. 3) Overburden will be dumped in external dump in 30 m decks and up to a
maximum height of 30 meters.
4) Dump bench slope will be maintained at 370, OB Bench slope- 70
0 and Overall
pit slope will be 370.
25
5) Track dozers will be deployed for shaping the dumps. Benching the dump and
plantation over the dump will help in better stabilization of dumps and reduction
of soil erosion. 6) Internal dumping of overburden will be carried out in 20-30 m height benches.
5.3 Mining Parameter
Considering the geo-mining characteristics of the deposit, the mine is proposed to
be worked by Conventional Mining Equipment (CME) Technology (Shovel /Backhoe -
Dumper system). All the overburden/parting is proposed to be excavated by shovel/
dumper combination with and without dragline. The coal horizons is proposed to be
extracted by hydraulic shovels/backhoes and transported to Coal Stockyard by rear
dumpers. The proposed mining system parameters for coal mining and OB removal are as follows.
1) Mining Benches
a) Maximum Bench Height
Dragline bench – 35 m 20 Cu m rope shovel bench – 15 to 18 m 8.3 Cu m hyd shovel bench – 12 to 15 m 4.5 Cu m Hyd shovel bench – 10 -12 m
b) Minimum Bench width
Working Bench width for 4.5 cum Hyd Shovel – 40 m Non-Working Bench width for 4.5 cum Hyd Shovel – 25 m Working Bench width for 8.3 cum Hyd Shovel – 50 m Non-Working Bench width for 8.3 cum Hyd Shovel – 30 m Working Bench width for 20 m Rope Shovel – 60 m Non-Working Bench width for 20 m Rope Shovel – 35 m Bench width of dragline – 60 to 70 m
2) Width of the permanent haul road – 30 m 3) Width of the temporary transport - 20 m
4) Usual height of the spoil dump bench – 30 m
5) The width of the active dump bench – 60 m 6) Bench slope working
OB Bench : 700
Coal Bench : 700
Dump Bench : 370
7) Overall pit slope : 370
No of annual working days : 330 No of daily shifts : 3
Duration of shift, hours : 8
Annual productivity of excavators is based on the following considerations apart
from the above design criteria:
a. Hardness of OB & Coal b. Specific gravity of OB & Coal
c. Swell factors of OB & Coal
d. Availability of HEMM e. Utilization of HEMM
26
5.4 Main mining equipment

5.5 Drilling and Blasting pattern
Main overburden comprises of clay, sandstone/clayey sandstone and shale which are friable in nature. Hard strata will be loosened by using selective blasting. Drilling of top OB and dragline benches envisages to be done by 250 mm drill whereas drilling of partings and coal envisages to be done by 160 mm drills. Drilling of coal & OB
benches is recommended to be done vertically at 900. Slurry explosive in cartridge
/site mixed slurry will be utilised for better result and enhance safety with proper stemming material. Secondary blasting is not in any circumstances. Mine shall create proper explosive storage capacity to cater daily explosive requirement to meet the annual coal target.
The mining plan envisages following type of drills for dragline bench /top OB bench
and partings and coal given in Table-20
Sr No Top OB /dragline Partings/coal
1 250 mm dia drill 160 mm drill
2 Blast hole depth- Max depth – 10 m 35 m dragline
18 m (20 cum Rope shovel)
15 m (8.3 cum Hyd Shovel)
12 m (4.5 cum Hyd shovel)
5.6 Blasting Pattern
A powder factor 0.125 to 0.167 kg/m3 of waste (average: 0.143 kg/m³) is
applicable, depending on rock conditions. Slurry / Emulsion Explosives are used. Rows of holes will be initiated through delay detonation of 25 to 50 milliseconds. Drill hole spacing would be 3m by 5m to 4m by 5m based on strata condition
5.7 Population Projection
The following villages are likely to be affected due to mining & its related activities:
About 485 number of project affected families involving about 2036 project affected persons will be affected as per census 2011.
It is obvious to assume that the activities of the mining operations will improve the
socio-economic levels in the study area. The anticipated impact of this project on
various aspects is described in the following sections:
a) Impact on Human Settlement
Human settlement is expected to increase after this project gets operational
b) Impact on Population Growth
This project will have an impact on the population growth, as it will provide good
value of employment to the families in the nearby villages. Preference will be given
to local unemployed youth for employment during development of mine and in
operation of mines which will substantially increase the income status of population
of the area and due to migration of people from outside area will be having impact
on the area
28
c) Impact on Literacy and Educational Facilities
The literacy level of the project area is likely to increase as there will be influx of
many educated people taking up jobs in the mine, which is likely to result in establishment of better educational facilities.
d) Impact on Civic Amenities
The impact of mining on the civic amenities will be substantial after the commencement of mining activities. The construction of new roads in the project
area will enhance the transportation facilities.
e) Impact on Health Care Facilities
It is imperative to have proper health care facilities near the mining area. Health care centre will be developed at proposed residential colonies, which will also
extending the medical facilities in the surrounding villages through its rural welfare
schemes.
f) Impact on Economic Aspects
The proposed mining activities will provide employment to persons of different skills
and trades. The local population will have preference to get an employment. The
employment potential will ameliorate economic conditions of these families directly and provide employment to many other families indirectly who are involved in
business and service oriented activities. This in-turn will improve the socio-
economic conditions of the area.

9. ANALYSIS OF PROPOSAL (FINAL
RECOMMENDATIONS) Financial and Social Benefits
The project will improve the socio-economic status of the society in the region by generating direct and indirect employment opportunities. The project will contribute
additional revenue to the State & Central exchequers in the form of taxes, cess, etc.
The anticipated positive impacts of the project are explained below:
Human settlement is expected to increase after this project gets operational. In the
long term, the project will have impact on the population growth due to migration of people from outside area. Indirect employment opportunities will also add to this.
35
The literacy level of the project area is likely to increase as there will be influx of
many educated people taking up jobs in the project, which is likely to result in
establishment of better educational facilities.
The impact of the project on the civic amenities will be minimal. Health care
facilities will be developed for the employees of the proposed project. These medical
facilities will be extended to surrounding villages.
The project related construction activities will benefit the local populace in a number of ways such as supply of construction labourers – skilled, semi-skilled and un-
skilled, tertiary sector employment and provision of goods and services for daily
needs including transport. The proposed project will provide employment to the
skilled as well as un-skilled persons. The local population will be given preference
depending upon their suitability to the job requirement. Besides direct employment,
indirect employment opportunities will also open up. The project will have positive
impact in the region. Quality of life of the people will improve, which in-turn will improve the socio-economic conditions of the area.
