2.4.2 Local Geology
Red and sandy soil covers the periphery of the Q.L area. The area is mostly consists of
big granite boulders on the surface. How ever the size of boulders varies from 1-3 m3
will be utilized for marketing after dressing. After removing such boulders and soil the
sheet rock will be reached. The subject area belongs to a mound raising to a height of
about 21.0 from ground level. The granite is exposed as a small hill in the centre portion
with steep slopes and soil is covering the foot portion. However the granite sheet rock is
well exposed without any over burden. It represents late magmatic injection of closepet
granite. The rock is essentially composed of Quartz & Plagioclase feldspar as essential
minerals and other mafics like Horbland, Boitite and Mica, etc., as accessory minerals.
The rock is compact and moderately hard
2.5 GEOLOGICAL RESERVES:
Based on the prospecting work carried out and the present exposure of the rock, the
reserves of the area have been estimated by the following parameters. We have taken
10.0m as proved zone and 2.5m as probable and possible zones in this area the recovery
factor is taken only 19%.

MINEABLE RESERVES AND THE LIFE OF THE MINE:
Initially, the total quantity of mineable reserves is considered as (economic) marketable
reserves. In this way a total mineable reserves of 27154m3 are available in this Q.L. area.
The production is proposed to obtain 1043m3 per year. At this rate of production, the
expected life of the mine is calculated as given below.
Life of the Quarry: Mineable Reserves/Annual production = 27154/1043 = 26 Years
2.6 MINING
Type of Mining: Open cast method of mining is carried out in this mine by manually
and semi mechanization by using compressor operated jack hammer drills, excavators,
and dumper etc., Transportation will be made by trucks to dispatching point.
Brief Description : (existing method of working) :
The mining operations are carried out by semi-mechanization as open cast mining.
Hydraulic excavator and compresses operated jack hammers were used for cutting the
rock. Close spaced drilling of 0.2m was adopted along a straight line and charged with
low explosives to avoid feature cracks.

K.Govardhan Reddy
Global Enviro Labs, Hyderabad 7
The details of machinery proposed to utilize at quarry are as follows:
a. Since it has been decided to undertake semi-mechanized mining operations, the
following mentioned mine machinery will be deployed.
i. Excavator – 1(Bucket capacity 1m3, Boom length, 7m, Model: Tata Hitachi
200Lc)
ii. 50 CFM-Air compressors – One
iii. Jack Hammers – three units.
iv. 17 Tonnes Tippers – 2 Nos.
Minor Tools: Chisels, Crowbars, Pick axes spades and hammers of different sizes.
Removal / Excavation of O.B. and other Quarry Waste :
The South- Eastern side of the area is selected for dump yard for next five years and the
waste will be stocked over a length of 40 mtrs. with width of 30 mtrs. grow a height of
20.0 mtrs. Step dumping will be resorted. This material can be utilized to fill the pits after
quarry operations are over. When the dumps reach their optimum height suitable
greenery will be grown on this dumps to stabilize them.
Separation of large primary Blocks from the mother rock by pre-splitting
(Primary):
The mining will be followed in the form of linear cut method. This involves loosing of
the primary block from mother rock. Hence primary cutting will be done by line drilling
method where close spaced parallel holes along straight line will be made. Line drilling
method is used for separation of primary blocks.
i) Once the free face is developed in working place, the primary cuts is taken up
over a maximum length of 10mtrs to a width of 3mtrs and to a depth of 6mts depends
upon the joints availability. These dimensions are confirmed as for field studies.
Primary block will be cut into secondary blocks by Jackhammer drilling and wedge
cutting and this block will be dislodged from in-situ position by an excavator.
ii) Line drilling method will be used for cutting the primary blocks which involve
drilling and blasting.
iii) The holes are charged with low explosive cartridge like gun powder and non-
delay detonators for smooth blasting.

iv) The use of delay detonates causes fragmentation and cracks in rocks. The non
detonating cords are inserted into the holes and the holes are stemmed with muck and
plugged at the mouth and fired.
v) Thus the block will separate from the mother rock, which is pulled off from the
face with cranes or shovel.
Sub-Division of large Primary Blocks into Secondary Block:
This will be done drilling close spaced holes (along a line) down to the depth and the
secondary block will be removed easily by just pulling it with the help of proclain. Close
spaced holes will be drilled to the half the length of the block on either side of it by using
wedges blocks can be separated.
Magazine:
Smooth blasting techniques and special explosives and silent on explosive demolishing
agent like ACCONEX will be used. An area is demarcated within the lease area for
portable magazine. This site is located at a safe distance from the quarry, strictly adhering
to the rules and regulations laid down for safe storage and handling of the explosives as
per the explosives act. The applicant at the moment is not in possession of blasting
license. He will apply for a licence as soon as the Q.L is granted.
Drilling and Blasting :
Drilling and Blasting plays vital role in determining the size and shape of rough blocks.
Drilling pattern is important in developing a working face and also preparing the rough
blocks suitable for their use in appropriate processing units. Even though, there are no
important places in and around the area, blasting will be carried with all precautionary
measures.
Drilling Parameters:
i. Drill holes diameter – 74/Pmm.
ii. Depth and inclination of the blast holes. 3 meter in case of separation primary
blocks depending on the block size. Then the drill-hole will be vertical.
iii. Spacing and burden : 1.5 x 3m.

iv. Stemming and charging of the blast hole. The Blast hole will be charged with 100
grams of explosives and filled with clan pills subsequently; the slot hole will be
stemmed.
v. Explosive type (1) Slurry based explosives or Gun Powder.
Production of Commercial Blocks:-
Major boulders exposed are used for small size marketable blocks. After primary
separation the rock mass will be carefully examined to avoid hair line cracks, mineral
segregations and veins etc., the dressing of the rough blocks will be made by chipping the
edges and geometrically equating the edges of the block at the dressing yard. The rough
blocks obtained after primary cut it will be dressed for obtained good geometric shape of
granite. Thus the commercial blocks are produced.
2.7 MINERAL PROCESSING
The Lessee intends to export and as well as sell the raw blocks for the processing units in
the country. The lessee does not possess a processing plant at the moment.
2.8 SITE SERVICES
The rest shelter cum office, First aid room, and toilets will be constructed in the area. The
roof will be of asbestos sheets covered by hay to keep it cool in summer. A first aid
certificate holder will be the in charge of the first aid room. Protected drinking water will
be provided and stored in earthen pots.
2.9 EMPLOYMENT POTENTIAL

3. EVALUATION OF IMPACTS
3.1 INTRODUCTION
Opencast mining activity causes some adverse impacts on the surround environment
unless proper environmental management plan is adopted. Selecting suitable sites for
mining and adopting the guidelines prescribed by the Ministry of Environment & Forests
(MoEF) and Indian Bureau of Mines (IBM), one can minimize the major possible
impacts.
In this chapter, an attempt has been made to quantify the possible environmental impacts
on various features such as air, water, noise, land, ecology and socio-economies. The
following aspects have been studied to identify the possible impacts while achieving the
total production of 1043 Cum/Year of Colour Granite.
The magnitude and significance of the environmental pollution caused by mining
depends on method of mining, scale and concentration of mining activity.
3.2 AIR ENVIRONMENT
The impacts on air environment from a mining activity depend on various factors like
production capacity, machinery involved, operations and maintenance of various
equipments and vehicle. Apart from these, there will be other activities associated viz
transportation of mineral and waste, stocking facilities and dump management within the
mine lease area that may contribute to pollution.
3.2.1 SOURCES OF DUST EMISSION
Mining is carried out by open cast semi mechanized method by using jack hammer
drilling & wire saw cutting and using low explosive blasting. Based on the various
operations involved in the production of minerals, the various emission sources has been
identified as given below.
EMP Report For Colour Granite Mine of 1.00 Ha, located in Nagarur Village, Aspari Mandal, Kurnool District , A.P.
K.Govardhan Reddy
Global Enviro Labs, Hyderabad 11
a. Point sources
b. Area sources.
c. Line sources.
Drilling operations of the mine are considered as point sources. Extraction of mineral
from mine, are considered as area sources. Transportation of material from mining
benches to various end points are considered as line sources. The impact of above sources
on air environment is discussed below:
a) Drilling & Blasting
One the boulder is freed by removing the soil and waste rock surrounding it, a series of
holes are drilled by compressed air using Jack Hammer at a regular interval of 15-30 cms
depending on the size of the boulder, the depth of the hole depends on the height of the
boulder and the holes are drilled up to the bottom leaving about a foot at the base. The
holes have to be perfectly straight and vertical so that the vertical split is obtained. Line
drilling machine can be used to drill straight holes. Feather and wedges are inserted into
the holes and hammered continuously applying uniform pressure and the boulder splits
vertically. Similarly dressing is done and the boulder is given a rectangular shape. All the
defects are avoided during the dressing stage. Diamond wire saw may also be employed
to dislodge the block from the parent rock.
Drill hole pattern will be uniform single lined pattern, equidistances holes from 0.33 m to
0.75 m , 4.5 m in depth. Spacing depends upon the size of the boulder, in general it 15
cms from hole to hole for better splitting.
The concentrations due to low explosives blasting will be confined to a maximum
distance of 10 m from the area of blasting. These concentrations will not be emitted
continuously. However presence of personnel near the blasting site during blasting will
be totally avoided. So, the impact of blasting on the air environment will be minimal.
b) Extraction & Loading
Extraction & Loading will be done by a crane and excavator and these activities of mine
operation is contributing to the area source emission and the extent of influence of this
operation is about 100 m2.

K.Govardhan Reddy
Global Enviro Labs, Hyderabad 12
c) Haulage &Transportation
In the operating mine, the dressed blocks from mine face to the consumers is transported
by hired trucks. The trucks will be well maintained so that exhaust smoke does not
contribute abnormal values of noxious gases and unburnt hydrocarbons. The other
sources of air pollution is due to the dust generated during the movement of tippers on the
haul road.
The above sources, which include drilling, low explosives blasting, excavation, haulage
for transport of blocks will contribute to dust pollution in the air.
3.2.2 ANTICIPATED IMPACTS
The impacts envisaged due to mining activity are evaluated based on various factors. The
emission inventory of the pollutants is as follows, the main air pollutant would be dust or
particulate matter generated by handling and transportation of Colour Granite . But the
impact of mining operations on air quality is minimum as mining involved method by
using jackhammer drilling & wire saw cutting & low explosive blasting and as the
production quantity is very less i.e. 4.172 Cum/Day only.
3.2.2.1 Dust Generation and Control
The air pollutant would be dust or particulate matter generated by handling and
transportation of granite blocks. The existing ambient air quality at quarry lease area is
within the limits prescribed by A.P.P.C.B. The envisaged production of minerals is only
4.172 Cum/Day. The dust generated due to mining operations will be controlled by water
sprinkling through water tankers
3.3 NOISE ENVIRONMENT
Noise will be produced at the mine is due to operations of machinery, drilling, blasting,
and movement of vehicles. The noise generated by the mining activity is dissipated
within a small zone around the mine. The present noise levels at quarry lease area are
within the limits prescribed by A.P.P.C.B. There is no major impact of the mining
EMP Report For Colour Granite Mine of 1.00 Ha, located in Nagarur Village, Aspari Mandal, Kurnool District , A.P.
K.Govardhan Reddy
Global Enviro Labs, Hyderabad 13
activity on the vicinity however; pronounced effect of above noise levels will felt only
near the active working area and on the personnel working in the vicinity. The impact of
noise on the villages is negligible as the villages are located far from the mine site.
3.4 WATER ENVIRONMENT
The Mining activity will be carried out on mound slope will not have any effect on the
ground water and the static water table in this area is below 35 m.
3.4.1 Impact on Surface Water
There are no major streams and rivers, which can get effected by the mining. Hence,
there will be no effect on the surface water.
During the present plan period quarrying will go to depth of 10 meters from the present
level of mining. During the monsoon period, the rainwater, if gets stagnated, will be
drained out. The benches will made with an inward slope to facilitate run off more faster
on to the mine floor. Small bunds, garlands and silting tanks also will be constructed to
minimize inflow muddy water which carry fine material.
3.4.2 Impact on Ground Water
Mining activity will be above the BWL (35 m). Hence, there will be no effect on the
ground water regime.
3.4.3 Impact on Water Quality
Water quality in the buffer zone have indicted that the ground water is free from heavy
metal concentration and this mining activity will not interference on the water quality.
3.4.4 Water Consumption & Wastewater Generation
The water requirement for this proposed mining activity will be 6.5 KLD. Breakup
details are:

Sl. No: Purpose Quantity (KLD)
1 Dust suppression purpose 4.5
2 Domestic purpose 0.5
3 Greenbelt purpose 1.5
Total 6.5
There is no generation & discharge of wastewater from this mine.
3.5 LAND ENVIRONMENT
Various components of land environment have been identified for study of impact of the
mine operations. Details of the same are given below:
3.5.1 Solid Waste Generation
Removal of weathered rock and the rock waste is the only solid waste that will be
generated from this mine. Some of the material from the waste may be sorted out and
used for making small blocks to be used by the local unit for making tiles. The market for
tiles is good at the moment and they will offer a better substitute for marble in terms of
price and quality. Some rejected and unsorted material may be used in the civil
engineering projects in the vicinity of the area. The waste material can also be crushed
into smaller sizes and can be used as road metal
The waste generated during the five years may be dumped in the zone separately reserved
for dumping along South West Part of the quarry lease area (Within the quarry lease
area). The dump will be designed in such that it will have slopes equal to the angle of
repose of such material. Garland drains have to be sunk along around the leading edge of
the dump. A retaining wall will be constructed around the dump to preventing the
slanting of boulders Care will be taken to minimize the waste generation at the source.
About 4447 m3/Year of waste will be generated from this mine. Waste will be stocked
over a length of 40 mtrs. Width of 30 mtrs. To a height of 20.0 mtrs., in the South-
Eastern side of the area. During the first five years about 22235 m3 of waste material will
be generated.

3.5.2 Impact on Land use
The mine is located in an area of 1.00 Ha. No forestland is involved.
After the operations cease, the mine spoiled area will be back field. It may not be
possible to complete regain the original topography of the area. During quarrying
whatever solid waste is generated shall be dumped at dumping site inside the Q.L. area.
The mining lease area is not a part of any type of forest. Entire mine lease area is govt.
land hence all the impact on land use is positive because aesthetic environment will not
be effected, as the mine is located on a plain with some bushes.
Due to opencast mining activities, the landscape will be slightly changed. There
will be no land subsidence as the country is made up of hard rock. The Soil cover in this
mine is almost nil and Agriculture is seen mainly in the plains in the vicinity of the lease
area and the mining will not have any impact on the agricultural pattern. Only few bushes
will be cleared to facilitate mining and other related activities and there are no big
trees, which may have to be cut.
3.5.3 Impact of Ground vibrations
Fragmentation of rock by blasting is an important operation in mining project, where hard
rock occurs. Blasting will be done only when it is absolutely necessary, using low
intensity explosives.
Blasting of the mineral at the proposed mine will be done by using Low-density
chemical explosives like ECM/ CaOH will be used. Sometimes smooth blasting may be
done using silent non-explosive demolishing agents like Acconex.
The ground vibrations caused by blasting will not have any affect as the mining is on a
mound and the vibrations will be minimum and will not be carried too far due to the hard
nature of the rock.
3.6 BIOLOGICAL ENVIRONMENT
There is no adverse impacts are anticipated due to the proposed mining activity on
biological environment. However, with the implementation of the environmental
EMP Report For Colour Granite Mine of 1.00 Ha, located in Nagarur Village, Aspari Mandal, Kurnool District , A.P.
K.Govardhan Reddy
Global Enviro Labs, Hyderabad 16
management measures, there will be improvement in the parameters of biological
environment.
The tree species found with the core zone represent the common type of flora species
along with small shrubs and bushes. Due to mining activities community structure of the
vegetation will not change. Whereas diversity of plant species and food web index of the
area reduced to certain extent.
However, if the proposed reclamation of the mining area and dumped out area using
proper re-vegetation techniques and development of green belt around the ultimate limit
and roadside there shall be an improvement in the species diversity and food web index
compared to the existing level.
3.7 SOCIO- ECONOMIC ENVIRONMENT
3.7.1 No Rehabilitation
The mine area does not cover any habitation. Hence the mining activity does not involve
any displacement of human settlement. No public buildings, places, monuments etc. exist
within the lease area or in the vicinity. The mining operations will not disturb/ relocate
any village or need resettlement. Thus no adverse impact is anticipated.
3.7.2 Improvement in Socio Economic Status
It will be obvious to assume that the activities of the mining operations have to be
produced some improvements in the socio-economic levels in the study area.
The Lessee will provide employment to local population and it will give preference to the
local people whenever there is requirement of manpower.
The proposed mining activities will provide employment to persons of different skills and
trades. The local population is the largest plausibility among these employees. The
employment potential ameliorated economic conditions of these families directly and
provided 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.

3.7.3 Occupational Health and Safety
The mine is going to be developed mainly semi mechanized opencast method by using
jackhammer drilling & wire saw cutting & low explosive blasting. No major crushing or
pulverization will be done here. The small-scale mining will not have any ill effects on
the health of labour.
Excessive dust and noise are the chief health hazards for the miners. As already
mentioned these causative factors are well within the safety limits and the proponents
will strictly implement the prescribed safety measures. The health of the workers will be
regularly checked and suitable medical facilities should be created on or close to the site.
Highest safety will be ensured in the working conditions of the miners.

4. ENVIRONMENTAL MANAGEMENT PLAN
4.1 INTRODUCTION
The mining development in the study area needs to intertwined with judicious utilization
natural resources within the limits of permissible assimilative capacity. The assimilative
capacity of the study area is the maximum amount of pollution load that can be
discharged in the environment without affecting the designated use and is governed by
dilution, dispersion and removal due to natural physio-chemical and biological processes.
The Environmental Management Plan (EMP) is required to ensure sustainable
development in the study area.
This chapter covers the genesis of pollution, the principal sources of pollution, the nature
of pollution, the proposed measures required for meeting the prevailing statutory
requirements of gaseous emissions, wastewater discharge characteristics, noise levels etc.
for environmental management purpose in connection with the mining and mining related
activities in the study area.
This section discusses the management plan for mitigation/abatement impacts and
enhancement of beneficial impacts due to mining. The Environmental Management Plan
(EMP) has been designed within the framework of various Indian legislative and
regulatory requirements on environmental and socio-economic aspects.
Environmental Management Plan giving the environmental protection measures at mine
to meet the stipulated norms of IBM/MoEF are as detailed.
4.2 AIR POLLUTION CONTROL MEASURES
The present ambient air quality measurements in the mine area are well within the limits.
Due to the proposed production of 1043 Cum /Year of Colour Granite , there will be
marginal increase in dust concentrations.
EMP Report For Colour Granite Mine of 1.00 Ha, located in Nagarur Village, Aspari Mandal, Kurnool District , A.P.
K.Govardhan Reddy
Global Enviro Labs, Hyderabad 19
Mitigative measures suggested for air pollution control are based on the baseline ambient
air quality monitoring data. From the point of view of maintenance of an acceptable
ambient air quality in the region, it is desirable that air quality should be monitored on a
regular basis to check it vis-à-vis the standards prescribed by CPCB and in cases of non-
compliance appropriate mitigative measures shall be adopted.
The following dust prone areas are identified for adopting proper control measures in the
mine area.
i) Drilling & Wire Saw Cutting & Blasting
ii) Excavation
iii) Transportation
The environmental control measures which will be implemented to control the fugitive
dust released from the proposed production are given below:
Wet drilling system & Dust proof
Optima Wire Saw Cutting (using water reduces dust)
Use of sharp drill bits for drilling holes. The charge concentration of the
explosives will be between 10 – 40 grams per linear meter.
Water sprinkling arrangements such as specially fabricated tankers mounted on
tipper are deployed at mine site to control the fugitive dust generation from the
haulage roads.
Regular grading of haul roads and service roads to clear accumulation of loose
material
The blasted blocks (temporary) are wetted by spraying water
Avoiding blasting during high windy periods, night times and temperature
inversion periods.
Excavation operations are suspended during periods of very strong winds.
Massive afforestation for control of dust
Spraying of water on sub grade stacks

The vehicles and machinery are kept in well-maintained condition so that
emission of fugitive constituents is minimized.
Plantation of wide leaf trees, creepers, tall grass around working pit, along roads
will help suppress dust.
Tall trees with an average height of 5 m will be developed all along the boundary
of the lease area to minimize the dispersion of the dust from the mining.
Periodical monitoring of air quality to take steps to control the pollutants.
4.2.1 OCCUPATIONAL HEALTH & SAFETY MEASURES
All the precautions would be adopted to prevent dust generation at site and to be
dispersed into the outer environment. However, for the safety of workers at site, engaged
at strategic locations/dust generation points like drilling, loading and unloading points,
etc., dust masks would be provided. Dust masks would prevent inhalation of RSPM
thereby reducing the risk of lung diseases and other respiratory disorders. Regular health
monitoring of workers will be carried out.
4.3 NOISE POLLUTION CONTROL MEASURES
The ambient noise level monitoring is carried out in and around the proposed mine shows
that ambient noise levels are well within the stipulated limits of CPCB.
Noise generation may be for an instant, intermittent or for continuous periods, with low
to high decibels. Periodic inspection and checks of the risk prone areas and equipments
have to be conducted.
To control noise pollution during the proposed mining operations following steps will be
practiced.
The noise generated by the machinery will be reduced by proper lubrication of the
machinery and equipment.
The workers employed should be provided with personal hearing protection
equipment, with earmuffs and earplugs combined, as a protection from the high
noise level generated at the plant site.
EMP Report For Colour Granite Mine of 1.00 Ha, located in Nagarur Village, Aspari Mandal, Kurnool District , A.P.

Global Enviro Labs, Hyderabad 21
The provision of green barrier along the boundary will further reduce the
propagation of noise level generated.
Limiting time exposure of workers to excessive noise.
Speed of trucks entering or leaving the mine is limited to moderate speed of 25
kmph to prevent undue noise from empty tippers.
Safety in Blasting
Care should be taken to evacuate the mining area completely at the time of low explosive
blasting operations. The blasting team should be equipped with all personal safety and
precautionary measure. The following safety measures will be given attention while
conducting the blasting operations.
A blasting SIREN should be used at the time of blasting for audio signal.
Before blasting and after blasting, red & green flags should be displayed as visual
signals.
Warning notice boards indicating the time of blasting and NOT TO TRESPASS
are displayed prominently.
4.4 WATER POLLUTION CONTROL MEASURES
The action program for minimizing adverse affects on water regime is to prevent wash-
off of mine water and uncontrolled run-off water during monsoon. Proposed measures for
this are as follows:
a) Building/extending of retention/toe walls at the foot of the dumps
b) Construction of Garland drains along the slopes to divert the rainwater course
away from the dumping areas.
c) Covering of dump slopes with grass plantation to stabilize and prevent erosion.
d) Plantation of trees along the ridges and slopes.

4.5 LAND ENVIRONMENT
The Dhanbad declaration on Environmental Management in Mining Industry states “It is
imperative that in order to ensure the continued and sustained progress of the mining
industry in India, the environmental dimensions should be integrated into the planning,
design, development, operation and working practices of quarry on scientific and rational
lines, by the Governments and the industry in a mutually reinforcing manner”. The land
related Environmental Management Plan (EMP) has been presented here under two
sections viz., Soil & Water conservation and Afforestation.
Storage and Reuse of Top Soil:
Topsoil removed during clearing of the area for granite extraction shall be stacked
separately to check the erosion of the stacked soil. A retaining wall shall be constructed
all around the topsoil stockyard. Planting of grass and local species etc., are proposed on
the surface of this stack to prevent erosion and to increase the soil nitrogen. As per the
analysis of the soil samples they are found to be basic in nature. During afforestation, it is
recommended to plant fast growing species with good canopy cover and dense leaf
density and some ornamental species to give a good aesthetic look. It is recommended to
sow neem, mahogany plants as soil and climatic conditions are suitable for the growth of
these plants.
Solid Waste Management
Removal of weathered rock and the rock waste is the only solid waste that will be
generated from this mine. Some of the material from the waste may be sorted out and
used for making small blocks to be used by the local unit for making tiles. The market for
tiles is good at the moment and they will offer a better substitute for marble in terms of
price and quality. Some rejected and unsorted material may be used in the civil
engineering projects in the vicinity of the area. The waste material can also be crushed
into smaller sizes and can be used as road metal
The waste generated during the five years may be dumped in the zone separately reserved
for dumping along South West Part of the quarry lease area (Within the quarry lease
area). The dump will be designed in such that it will have slopes equal to the angle of
EMP Report For Colour Granite Mine of 1.00 Ha, located in Nagarur Village, Aspari Mandal, Kurnool District , A.P.
K.Govardhan Reddy
Global Enviro Labs, Hyderabad 23
repose of such material. Garland drains have to be sunk along around the leading edge of
the dump. A retaining wall will be constructed around the dump to preventing the
slanting of boulders Care will be taken to minimize the waste generation at the source.
About 4447 m3/Year of waste will be generated from this mine. Waste will be stocked
over a length of 40 mtrs. Width of 30 mtrs. To a height of 20.0 mtrs., in the South-
Eastern side of the area. During the first five years about 22235 m3 of waste material will
be generated.
Stabilization and vegetation of dumps:
The dumps will be stabilized and shaped trapezoidally. The angle of repose will be in
such a manner that the run off of material will be avoided. The trench will be dug around
the dump to avoid run off. The dumps will be safe-guarded by plantation of trees along
the slope and of the soil cover area. In first five years, it is planned to undertake
plantation of 50 trees per year on the slope of the dump, depending on facilities available.
Land Restoration/Reclamation:
Land restoration or reclamation of the area is very essential in any mining industry.
Proper measures adopted during restoration will control most of the adverse
environmental impacts of Quarry and also improve the aesthetic beauty of the area. Due
to the Quarry activities in this area the profile of the ground will change due to formation
of pits. At the end of the Quarry operations, the top soil/mineral rejects will be utilized
for back filling wherever suitable and rehabilitated.
Following steps shall be taken for improving and protecting the environment.
a) Quarry lease area
b) Surrounding the Quarry lease area.
c) Surrounding the statutory buildings
d) On the undisturbed virgin lease area.
Surrounding the Mining area
The dust generated during the quarrying operations will be carried by wind and will be
deposited over the trees and on the adjacent area around the quarry in the buffer zone. To
filter this dust, a green belt of 10m width shall be developed along the quarry lease area
EMP Report For Colour Granite Mine of 1.00 Ha, located in Nagarur Village, Aspari Mandal, Kurnool District , A.P.
K.Govardhan Reddy
Global Enviro Labs, Hyderabad 24
i.e., around ultimate pit limit, this green belt will also act as sound barrier. In between the
tree saplings, grass and bushes shall be grown. Creation of the green belt around the lease
areas shall be undertaken on priority basis and shall be completed concurrent to Quarry
over a 10-year period.
Surrounding the statutory buildings
All around the proposed statutory buildings and along the road sides trees shall be planted
in addition to the existing ones which will protect the workers from the noise and dust.
To plant trees around the statutory buildings, the topsoil that is going to be mined from
the area shall be laid to form a strip of 10-15m width and 0.5m thickness.
On the undisturbed virgin lease area:
The undisturbed virgin lease area shall be utilized for afforestation purposes by
developing the area with local varieties. This work shall be done after the cessation of
Quarry operations.
Plantation Programme:
In every year about 50 mtrs, length of buffer zone will be planted along the boundaries on
Western side of the area. About 33 saplings consisting of Neem, Teak will be planted per
year over an area of 50m x 6m at 3m grid interval.
Apart from the green belts and aesthetic plantation for eliminating fugitive emissions and
noise control, all other massive plantation efforts shall be decided and executed with the
assistance and co-operation of the local community. Based on the community needs the
afforestation would mainly aim at:
a) Protection & Development of Natural Vegetation
b) Protection of soil erosion
c) Plantations of fuel wood blocks to meet the energy requirements.
4.6 SOCIO ECONOMIC BENEFITS
There is positive impact on socio-economics of people living in the villages. The villages
in buffer zone depend upon agriculture. Mining operations in the subject area has positive
impact by providing direct and indirect job opportunities. There will be indirect
employment opportunities in transportation of ore to destination.

4.7 POST PROJECT MONITORING
The Lessee will monitor the environmental parameters as per APPCB/IBM/CPCB
guidelines
4.8 IMPLEMENTATION OF EMP & MONITORING PROGRAMME
The environment management plan is detailed on the basis of impact assessment. Control
and mitigation measures for the adverse impacts envisaged. As the major environmental
attributes have been confined to the project area alone, implementations of the proposed
control measures and monitoring thereof will be undertaken on the regional basis. The
Lessee will ensure the implementation of the measures within the mine area and carryout
efficient monitoring. In order to implement the measures suggested for mitigating the
adverse impacts on the environment, it is suggested to monitor the environmental
parameters regularly.

CONCLUSIONS, SUGGESTIONS/RECOMMENDATIONS
The Mining method proposed as per the approved Mining Plan from Dept. of Mines &
Geology is small-scale semi mechanical mining activities without deployment of deep
hole drilling and use of Heavy machinery. The actual method of mining Color Granite is
by slicing. Based on the appraisal of the existing environmental scenario coupled with
the assessment studies carried out, it is concluded that there is no long term
environmental impact due to the Colour Granite quarry at the lease area.
The particulate matter getting airborne from the mining activity gets dispersed in close
proximity itself and settles down early. The noise levels due to the proposed quarry
activity are also not of a higher order that calls for immediate corrective measures. The
ground water analysis indicates that the sources do not get influx of pollutants from the
quarry activity. There is positive socio-economic front in the surrounding region due to
the proposed mining industry. The practice of afforestation scheme is a step in the right
direction towards achieving ecological balance.
Suggestions/Recommendations
Even though there is no perceptible impact from the quarry activity on the environment of
the region, it is imperative that mitigative measures have got to be implemented on full
scale for creating environmental balance and intern maintain the ecology of the region.
The following suggestions/recommendations merit due consideration in this regard.
As no control over wind can be exercised, the frequency of the dust
suppression measures like constant watering of the haul roads shall be
practiced.
Afforestation as envisaged in the mining plan is to be carried out so that it
not only enhances the green canopy but also stop the spread of dust
particles and air borne pollutants.
Surface water conservation measures and groundwater recharge be given
high priority.
