production 10249.20 (max) cum/Year of Colour Granite in Sy. No 227/1 of Gopalpur

village, M.Turkapally Mandal, Yadadri District of Telangana State. In view of the

shallow nature of the deposit, open cast mining method shall be adopted in a semi

mechanized manner by developing multiple benches.

The applied Quarry lease Area is located on Survey of India Toposheet No.56/K/10 and the area falls

between the 17° 40’40.77” N, 78°45’34.99” E. The quarry lease applied area is located at

1.0 km due South of Gopalpur village and M.Turkapally Mandal Head Quarters is

located at the distance of 06 km due South of the quarry lease applied area.

2.2 NEED FOR THE PROJECT

In order to meet the statutory requirements the lessee intends to obtain Environmental

Clearance from Statutory Authorities.

2.3 TOPOGRAPHY

The quarry lease applied area is located on a low N-S trending barren hill sloping on both

sides rising 13 M above ground level. The area is unfit for agriculture as it is strewned

with boulders.

The area fall partly on the Water Divide Zone. The drainage network is due West and

SW flows of the quarry lease applied area. The area around the applied area are barren

and Dry agricultural lands.

The quarry lease applied area is a part of barren hill raised 13 M above ground level

within the quarry lease applied area with topo relief in East direction. The exposures of

rock outcrops are abundant in N-S. The lowest contour is 581 M and highest contour is

594 M.




2.4 GEOLOGY

2.4.1 Regional Geology

The quarry lease areas comprise of Granites and Granitic Gneiss of Archean Age. Pink

and Grey Granites, Pink Alkali - Feldspar Granites and Gneissic Grano Diorite – Quartz

Diorite with enclaves of Supra - Crystals like Quartzite, Chlorite Schist, Hornblende -

Biotite Schist etc. constitute the Granitoid – Migmatite complex. These Litho units are

exhibit various geomorphic expressions like Domes, Inselbergs, Castle - Koppies and

Whalebacks and Basic Dykes forms Linear Ridges with moderate Relief.

The geological succession of the area as worked out by GSI (1991) is as follows:

RECENT SOIL / ALLUVIUM

Precambrian

Intrusive

Basic intrusive Dolerite / Porphyritic

Dolerites, Gabbro, Pyroxenite

Aplite / Pink Pegmatite / Quartz Reef /

Quartz Veins. Pink Whitish Fine Grained

Supracrustal

(Dharwars)

Amphibolites / Hornblende Schist /

Mica Chlorite Schist / Meta Basite / Meta

Volcanics / Quarzite / Banded Iron

Formations

Pre Cambrian Supra Crustal occurs as linear enclaves in younger granites.

The region of the quarry lease area is belonging to peninsular gneiss of Archaean group.

The Peninuslar Gneissic Complex comprising migmatite gneiss, grey granodiorite,

porphyritic granite and intruded by dolerite and aplite veins.

The Peninsular Gneissic Complex comprises gneiss-migmatite-granite suite of rocks.

They are highly variable in mineralogical composition appearance structure and relative

ages. The individual members have not been distinguished in a major part of the area.

However, granite and migmatite gneiss occupy a large part of the area, while bands of

relatively younger coarse-grained gneissic granite occur in the north eastern part.




The Karimnagar belt located along the tectonic joitns between the Dharwar belt and

bastra cratons in north eastern part of the state and made up of rocks of high grade

metamorphism, migmatisation and intense deformation. These granites, which are often

porphyritic, are intrusive into the gneissic terrain and contain alkali feldspar space. The

later in parts the colour to the granite which ranges from light to deep pink because of the

massive nature of these intrusive they are mineral for producing large size blocks.

The rock is exposed in the form of cluster of sheet.

2.4.2 Geology of the Area:

Entire quarry lease area is covered with colour granite which is rising up to 13 M above

ground level trending N – S, the strike length of the deposit in the applied area measured

257 M in the area with an average width of 153M.

Three sets of joints are recorded in the formation

1. N – S Vertical

2. E- W Veritcal

3. Horizontal / Sheet Joints

These joints are closely spaced on the surface. On the other hand they are widely spaced

in the depth as noticed in the quarry sections.

Regionally the area constitute a part of Peninsular Gneissic complex of Archaean, and

occupied by Prophyritic granite, white, grey and pink colour alaskitic granite, with

patches of amphibolites, hornblende schist bonded magnetite quartzites as enclaves in

both prophyritic and alaskitic granite.

The major litho units are extensively invaded by younger quartz, pegmatite, epitode,

calcite veins and also by dykes basic rocks.

The porphyritic granite along with intermixing of pink alaskitic granite forming as

mounds, ridges and hillocks in the area; contact of the rocks clearly indicate intrusive

relationship, young alaskites intruded into older porphyritic granite; which is locally

showing poorly developed foliation trending N – E.

The older basic enclaves of amphibolites hornblende schist show signs of metasomatism

in the form of flakes of biotitic. Number of acidic veins like pegmatite, quartz is




traversing the porphyritic granite trending in NNE – SSW. NE – SW to NNW – SSE to

NW – SE.

COLOUR GRANITE DEPOSIT

Area is characterized by rugged topography with isolated tors and inselbergs intervened

by plain land.

In quarry lease area, porphyroblastic granite occurs as massive exfoliation dome steeply,

sloping in all the direction. It is rising from minimum elevation of MSL 581 Mt to Max

elevation of MSL 594 Mt. It is uniform in mineral assemblage, texture, colour and devoid

of major joints, though few joints present, they are widely spaced with limited lateral

extent, along these joints, large boulders are formed from the domes.

However, due to very coarse grained nature of rock due to K. Feldspar crystals the rock is

prone to weathering. Hence, thick weathered mantle, soil core observed along the western

edges of the rocky outcrops with vegetal cover.

The granite porphyry has attracted the attention of the market by virtue of its pleasing

texture, where the orthoclase porphyries are unfiromly distribute in the form of elongated

or rougly oval shaped prophyroblasts of orthoclase in the mesostasis of quartz,

plagioclase, biotite and hornblend. In fact, the quartz grains with bluish tinge have added

more attraction after polishing.

Details of prospecting/ Mining already Carried Out: No Exploration/quarrying is

carried out in the area as the subject area is applied for grant of quarry lease.

2.5 GEOLOGICAL RESERVES

The quarry lease applied area is a part of barren hill raised 13M above ground level

within the quarry lease applied area with topo relief in East direction. The exposures of

rock out crops are abundant in N-S. The lowest contour is 581 M and highest contour

is 594 M.

The exposed outcrops upto 13M above the ground level and the reserves upto 20 M

below the surface are considered under proved Category of Reserves (upto RL 560 M)

and 20 M below the proved reserves (upto RL 540 M) are considered under Probable

Resources (Plate-III).




Hence, G1 (Proved) scale category as (111) code & G2 (Probable) scale category as

(122) is calculated.

As per UNFC guidelines the G3 (333) (Possible) category are not considered as they

are not mineable unless proved by exploration.

Saleable Blocks: Even after obtaining the 20% blocks the recovery of sizeable large

blocks would be around 25% and 75% would be marginal blocks by obtaining smaller

sizes.

Blocked up (211): 10,08,812.00 M3

Mineral Resources: (Mineral resources may be estimated purely based on level of

exploration, with reference to the threshold value of minerals declared by IBM)

Level of Exploration Resources in Million M3/Colour Granite

G1-Detailed exploration 0.139

G2-General exploration 0.048

G3-Prospecting -

G4-Reconnaiswsance -

Method of Estimation of Reserves:

As the area is virgin and no exploration is carried out in the area as the lease is yet to be

granted. Hence, the database of the existing quarrying pits around are extrapolated to the

subject area to arrive the profile of the deposit.

The exposed granite deposit is found to be irregular in shape, the volume of the deposit is

computed by Cross Sectional Area method by multiplying the sectional influence.

The cross sections were drawn perpendicular to the strike direction, the cross sectional

area of the individual sections are calculated to arrive at section area, the area thus arrived

is multiplied by the sectional influence of 50 M (average) to arrive the volume of rock

mass.

The Colour Granite is general occurs as massive formation and with joints spaced are

apart on surface and widens in depth, the sizeable blocks of dimensional stones are

anticipated to be obtained. Hence, a conservative recovery of 20% is arrived for Colour

Granite.

The cross section in E-W direction are drawn at equal interval of 50 M. 5 cross sections

A-A1 to E-E1 was drawn.

2.6 MINING

(Open Cast other than fully Mechanized / Semi Mechanized) : The method of

quarrying shall be opencast and Semi-mechanized on single shift basis. Excavations

shall be carried out by Jack Hammer drilling and blasting. Bench height and width will

be maintained at 6m height and 6 m width each respectively with overall slope at 60o.

Excavation and loading shall be carried out with simple excavators of capacity 0.9 to 1.1

m3 bucket capacity. This shall be utilized for developmental work, excavation and

loading into the trucks. Tippers of 10 T capacity shall be utilized for all transportation

purpose.

The Colour Granite in the quarry lease applied area is exposed on the surface with

boulders. Hence, it is proposed to mine the boulders / sheet by open cast, semi-

mechanized methods, by developing the benches of 6 height in and 6 M width. Wire Saw

cutting will be deployed based on the favourable conditions. The development of benches

in the sheet rock will be maintained @ 600

safety slopes.

The separation of blocks from the mother rock will be carried out by drilling and

chiseling with hammers with small pressure after wire saw operations, drilling and




dousing with excavators will be done by through poclain teeth or with bucket separating

from the mother rock.

The second splitting, dressing of blocks will be done manually or poclain bucket by tam

rock machine with drilling and splitting.

Therefore, mining operations are to be carried out in this area in 2 stages.

1) Development

2) Production

Stage- 1

The removal of weathered and under sized boulders will be cleared in the quarry lease

applied area for the next five years by using excavator.

The sheet that is exposed will be subjected to drilling, with compressors and tam rocks,

chiseling with hammers applying pressure by poclain teeth and splitting from mother

rock.

Rock splitting / Wedging : Thus 20’ x 20’ to 40’ x 20’ to 40’ mass will be separated

from mother rock by drilling the slotter holes on both sides of the mass and a top holes

intersecting these two holes and wiresaw rope is passed through and cutting is done

horizontally and vertically and by this there will be mass opening on all the sides from

the mother mass.

Stage-2

After removal of weathered and under sized boulders.

The large boulders will be subjected to splitting into required sizes of blocks

by using Jack Hammers by drilling series of deep holes at right angles at

regular intervals, later by inserting feather and wedges in these holes and

hammering with sledge hammer will release the blocks.

The boulders will be splitted to the required sizes with drilling and if required

by using chemical compound at the source only. The boulders separated will

be brought to the dressing yard for dressing.

If the boulders, which fit into the required market grade size will be

transformed into cuboids.




Secondary Splitting: After separation from the mother rock, it is properly checked by

washing with water to identify defects and cracks. Based on this observation, the size is

decided and the blocks are marked and separated by drilling and wedging.

The separated pieces will be examined for defects and lines, then the block or blocks are

marked in clear area and holes are drilled along the line of marking , with the help of

feathers and wedges the waste portions are separated forming a rectangular blocks. Any

bulges will be removed by drilling and wedging making it perfect blocks. A perfect block

is that all the sides shall make with each other 900.

Dressing:

Dressing of dimensional rough blocks for export: Dressing is final phase of mining

operation, wherein the secondary rough blocks are squared into regular perfect

rectangular sizes, thereby avoiding uneven bulge or cavities and other defects.

Jackhammers with compressor, feather end wedges and sledgehammers are equipments

generally used for dressing the block.

Dressing of rough blocks for domestic processing plant: Dressing by means of squaring

and splitting will be done for rough blocks of the size varying between 120 x 90 x 80 to

300 x 200 x190 M.

Description of granite processing plant: The lessee company does not possess processing

plant.

Drilling & Blasting : Drill hole of 6.25 M depth will be drilled in a single row

with spacing of less than 0.3 M and burden of 1.6 M or more shall be maintained

uniformly. This arrangement will yield rock size of 3 M x 2 M Cross section. A

bench height of 6.0 M will be tackled.

Drilling Parameters: Drill Hole Diameter 32 MM up to 9 M Long.

Depth and Inclination of Drill Hole: Generally drilled vertically in an alignment

however in primary cutting in the absence of sheet joints to develop bottom level,

horizontal holes also are drilled.

Explosive Type: Wherever required gunpowder is used for splitting the rock.




Machinery:

Excavator(Hitachi)200 1 NO

is 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

The mining activity will provide the job facilities to the local people. It will have 1 Mines

Manager, skilled & unskilled labour about 28 persons.




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 10249.20 (max) 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.

a. Point soruces

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.




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. 40.99 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 T.S.P.C.B. The envisaged production of minerals is only

40.99 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 T.S.P.C.B. There is no major impact of the mining 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 20 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 (20 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 indicated 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 5.5 KLD. Breakup

details are:

Sl. No: Purpose Quantity (KLD)

1 Dust suppression purpose 3.5

2 Domestic purpose 1.0

3 Greenbelt purpose 1.0

Total 5.5

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 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 40996.80 m3/Year of waste will be generated from this mine. The waste generated

will be dumped temporarily in the NW of the quarry lease area between the grids N

1956135 – 1956195 & E 262465 – 262570 covering an area of 3,438 m3 with an average

height of 6M with 450 slope angle with be formed. A retaining wall will be constructed

around the dump for preventing the slanting of boulder.

3.5.2 Impact on Land use

The mine is located in an area of 4.000 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

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 10249.20 (max) Cum/Year of Colour Granite, there

will be marginal increase in dust concentrations.




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.




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:

Building/extending of retention/toe walls at the foot of the dumps

Construction of Garland drains along the slopes to divert the rainwater course

away from the dumping areas.

Covering of dump slopes with grass plantation to stabilize and prevent erosion.

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.

Existing Land use pattern with already rehabilitated area and area matured for

reclamation is tabulated below:

During the first five years 14,248 m2 of the quarry lease applied area will be reduced

by18 M. The mining will after the shape of the present ridge with a large quarry pit.

Total Nil 1.938

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 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 40996.80 m3/Year of waste will be generated from this mine. The waste generated

will be dumped temporarily in the NW of the quarry lease area between the grids N

1956135 – 1956195 & E 262465 – 262570 covering an area of 3,438 m3 with an average

height of 6M with 450 slope angle with be formed. A retaining wall will be constructed

around the dump for preventing the slanting of boulder.

Stabilization and vegetation of dumps:

Waste dump yards are proposed in the quarry lease area. The dumps will have angle of

repose so that no creeping of material will occur. The dead end will be subjected to

vegetation by growing grass and bushes. Garland canal is proposed to be dug around the

dump and plantation will be taken up in this site.

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 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.

Afforestation Plan: The lessee proposed for afforestation in the north of the quarry lease

area within the 7.5m buffer zone over an extent of 450.00m2 between the grids N 00-S 50

to E 50- 150 in phased manner during the plan period with Neem plants.

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.

The details of investments to carryout the regular monitoring and pollution control

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 Colour 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.
