ENVIRONMENT MANAGEMENT PLAN
1.0 Introduction
This report discusses the management plan for mitigation/abatement of adverse
environmental impacts and enhancement of beneficial impacts due to mining. The EMP has
been designed within the framework of various legislative and regulatory requirements on
environmental and socio-economic aspects.
M/s. Dinesh Granite Exports filed an application for Colour Granite quarry with an extent of
5.0ha located at Survey No. 1, Addukonda Village, Tekkali Mandal, Srikakulam District,
Andhra Pradesh. Quarry lease deed executed work orders issued by The Assistant Director of
Mines and Geology, Tekkali vide proceedings no. 4835/Q/2002 dated 19.06.2003 for a
period upto 18.06.2023. Mining Plan has been approved by the Deputy Director of Mines
and Geology vide Letter No. 2356/MP-TKL/2016 dated 01.12.2016. It is proposed to extract
colour granite production of 12000 m3 annually by semi mechanized method mining. Capital
cost proposed for quarrying is Rs. 57 Lakhs.
M/s. Dinesh Granite Exports is conscious of its environmental responsibility towards the
society in minimizing the pollution load due to this project and accordingly decided to carry
out the Environment Management Plan. The objective of preparing environment
management plan is to delineate effective measures to control and to mitigate the
environmental pollution. This report presents the environment management plan, detailing
the environmentally sound technology and the measures needed to contain and mitigate the
anticipated environmental impacts due to the project.
1.1 Granite and its uses
Granite is a very common intrusive igneous rock. It is light-colored granulose plutonic rock
composed of the minerals feldspar, quartz and biotite & muscovite mica. These minerals
make granite white, pink, or light grey. Granite also contains small amounts of dark brown,
dark-green, or black minerals, such as hornblende and biotite mica. Granite is very hard and
dense. It can be readily cut into very large blocks and it takes an extremely high polish. The
name granite is derived from the Latin word granum, which means grain, an obvious
Dinesh Granite Exports Environment Management Plan
Team Labs and Consultants1-2
reference to the granular texture of granite. The average density of granite is between
2.65 and 2.75 g/cm3, with a compressive strength of above 200 Mega Pascal (MPa).
Uses
Granite has been extensively used as a dimension stone and as flooring tiles in public and
commercial buildings and monuments. With increasing amounts of acid rain in parts of the
world, granite has begun to supplant marble as a monument material, since it is much more
durable. Engineers have traditionally used polished granite surfaces to establish a plane of
reference, since they are relatively impervious and inflexible. Granite tables are used
extensively as a base for optical instruments due to granite's rigidity, high dimensional
stability and excellent vibration characteristics. Rough-cut and polished granite is used in
buildings, bridges, paving, monuments and many other exterior projects. Indoors, polished
granite slabs and tiles are used in countertops, tile floors, stair treads and many other
practical and decorative features. Presently, cut and polished granite slabs of 20 mm
thickness are preferred for flooring, while tiles of 10 or 12 mm thickness are used for
cladding.
1.2 Mining Technology
The mining operations are carried out by semi-mechanized opencast mining method. Mining
will be carried out by forming benches of 6m height and 8m width. The Colour Granite in
the quarry lease applied area is exposed on the surface with boulders. Wire Saw cutting will
be deployed based on the favorable conditions. The development of benches in the sheet
rock will be maintained @ 60° safety slopes.

2.0 Topography of the Area
The Q. L. area consists of mound of hillock which slopes in all the directions. The formation
is in the form of boulder and sheet of Charnockite Gneiss, which are of bluish in colour and
occupies most of the lease area. The maximum contour level is 210 m in the central part of
the Q.L area and the minimum contour 105 m in the southern part of the area. The relief is
therefore 105 m and slopes in Southern and western directions.
2.1 Regional Geology
In and around Srikakulam and Parlakimidi Blue and Brownish granite is extensively quarried.
It is a part of Eastern Ghat group of rocks consisting of Charnockite, Khondalite and
Granitoid a variety of hybrid rock formed by the interaction of Intrusive granite into the
Khondalite. The Eastern ghat group attains a maximum thickness in the Ganjam - Cuttack
tract. It occurs as ridges trending NE-SW. The eastern ghat belt exhibits high grade
metamorphism as evidenced by the presence of Garnet and Silliminite. The Charnockite
shows intrusive relation towards Khondalite and has itself under gone post migmatic
changes. Felspathic bands are common and are due to Granitisation.
2.2 Local Geology
The terrain in and around the area is of undulating in nature. The major portion of the area
is occupied by big boulders and sheet of Charnockite gneiss which consists of Quartz, Grey
feldspar, Silliminite and other Ferro Magnesium minerals like Hypersthenes, Hornblende,
Biotite and Garnet. The felsic and mafic bands alternate with each other to which imparts a
very good texture to the rock. The overall background of the rock is bluish. Two set of joints
are observed, one is parallel and the other perpendicular to strike direction. They are
widely spaced and are useful in splitting big blocks from the mother rock. The rock at places
is intruded by quartz vein and feldspar band. The weathering extends to a depth varying
from few inches to a foot in some areas. A megascopic and polished sample indicates that
the rock takes good polish and exhibits fine texture.
3.0 Exploration
a) Mining Carried out
Mining activity is under process in this mine lease area from the year 2003-2013 about
6671.814 m3 of granite blocks were produced.

4.0 Reserves
4.1 Estimation and Calculation of Geological Reserves
The reserves are estimated by cross sectional method. It consists of multiplying the sectional
area by the zone of influence which is the distance between the two cross sections. Based on
the information obtained from the mapping the area 'proved' category reserves may be
estimated from the top of the hill to a depth of 30 m, From the base of the proved zone, a 15
m depth is considered for the estimation of the reserves under the 'probable' category and
from the base of the probable zone, a 15 m depth is considered for the estimation of the
reserves under the 'possible' category. Section wise calculation of colour Granite reserves are
given in the table 1.3.

5.0 Mining
a) Type of Mining:
Opencast semi-mechanized method of mining deploying an excavator is proposed to be
undertaken in the area. The mining operation is proposed to be conducted in a very scientific
and systematic manner. The production will be carried out by forming benches of 6m height
and width will be kept more than the height i.e. about 8 m. The slope of the bench will be
maintained properly as per the stability of the strata and the overall slope angle of the pit will
be maintained not more than 30°.
Therefore, mining operations are to be carried out in this area in 2 stages.
i. Development
ii. 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, blasting 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 hole intersecting these two holes and wire
saw 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.
a. 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.
b. The burner cutters will be deployed for shaping the boulders.
c. 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.
d. If the boulders, which fit into the required market grade size will be transformed into
Dinesh Granite Exports Environment Management Plan
Team Labs and Consultants1-9
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 90°.

Generally drilled vertically in an alignment, however in primary cutting in the absence of
sheet joints to develop bottom level horizontal holes also be drilled.
iii. Explosive Type: gun powder.
6.3 Dressing
After primary separation the rock mass will be carefully examined to avoid hairline cracks,
mineral segregation’s 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 obtaining good geometric
shape of colored granite.
Dressing of dimensional rough blocks for export:
Dressing is the 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
the equipment generally used for dressing the block.

6.4 Solid Waste
The granite body exposed to the surface. Hence, the weathering on the surface of the rock
closely spaced joints and shears along with inherent defects like Moles, Dark patches and
acidic veins contribute a large extent of waste generation during the mining. The waste
generated will be dumped in the SW side of the quarry lease applied area covering an area of
9600 m2 with an average height of 30m with 45° slope angle will be formed. A retaining wall
will be constructed around the dump for preventing the slanting of boulders.

9.0 Environment Management Plan
Environmental protection is an issue that no organization can neglect and hope to survive.
The products of civilization are being dumped upon the environment to a degree that the
environment finds difficult to assimilate. The key to the success of the integrated approach to
pollution prevention and control is the management and operation of the organization.
Effective committed management delivers a successful operation. As total commitment to
the environment, not just for compliance with legal or regulatory compliance will be the
essence of environment management. Many companies have recognized the benefits of
implementing an effective environmental management system. Environmental management
plan can be effectively implemented to mitigate the pollution levels by observing the
following:
a. Pollution will be prevented or reduced at the source
b. Pollution that cannot be prevented will be recycled in an environmentally safe manner.
c. Pollution that cannot be prevented or recycled will be treated in environmentally safe
manner and
d. Disposal and other releases into the environment will be used only as a last resort and
will be conducted in an environmentally safe manner.
The proposed project is granite mine. The mine owners are aware of the adverse impacts due
to the mining activity and propose to initiate a number of measures for the environment
protection within the mine area and in the surrounding areas. The company has a stated
environmental policy of ensuring regulatory compliance with respect to the statutory laws
and regulations and those periodically issued by the Ministry of Environment, GOI, New
Delhi, CPCB, New Delhi and State Pollution Control Board.
9.1 Sources of Pollution and Control Measures
The sources of pollution are air and noise from the proposed activity mainly from Mining,
drilling and transportation of mineral. Waste material generation, dumping and restoration.
9.2 Air Pollution and its Control
The granite mining does not involve much dust formation. The dust would be generated
during drilling, blasting, quarrying and also during handling and transportation of the
material. The dust anticipated at drilling place will be suppressed by putting cloth around the
hole. Use of sharp drill pits for drilling holes and drills with water flushing systems (wet
Dinesh Granite Exports Environment Management Plan
Team Labs and Consultants1-14
drilling) to reduce dust generation. Water spraying to be adopted at Faces/sites before and
after blasting, Faces/sites while loading. Over charging of blast holes should be avoided.
Personal protective equipments like nose mask and goggles etc will be provided to the
workers. Regular water spraying on haul roads during transportation of mineral and waste by
water sprinklers. Over loading of transport equipments should be avoided to prevent spillage.
Also, measures such as covering tarpaulin over the loaded material will prevent spreading of
dust particles from the trucks. Speed controls on vehicle movements to limited speed. Wind
reduction control by plantation. Over burden dump has reached the optimum size, it will
covered with top soil and water will spread on top soil and grass will be developed on the
dump. Limiting the height and slope of the stockpiles can also reduce wind speed. Regular
checking and maintenance of vehicles should be conducted and pollution under control
certificate be obtained. Periodical monitoring of ambient air quality will helps to take steps to
control the pollutants.
9.3 Noise pollution and its control
The major source of noise pollution is due to drilling of drill holes, machinery, Blasting and
vehicular movement. Blasting operations will be carried out only during daytime so as to
avoid high noise intensity in night time. Noise barriers in the form of trees are provided to
attenuate the noise levels and green belt of 6m width shall be developed to mitigate
propagation of noise. Protective equipment to reduce the noise levels like ear muffs and
other protective devices will be provided to the staff working near noise generating sources
like drill machine operators and dumper drivers. Training would be imparted to mine
personnel to generate awareness about the damaging effects of noise. The transport activity
shall be restricted to day time to reduce impact on habitation. The engines of the tractors
shall be switched off during loading operation, and shall be periodically maintained to ensure
low noise levels. Proper maintenance of the equipment will also reduce the noise.
10.0 Occupational Safety and Health
Health and safety aspects of the mine will be taken care off as per the World Bank (WB)
guidelines on open pit mining. The guidelines provide the detailed information on the aspects
that are required to be taken into account for maintaining proper health and safety issues.
The workers continuously exposed to dust will be provided with protective devices like dust
mask to prevent respiratory disorders. The workers continuously exposed to a high noise will
Dinesh Granite Exports Environment Management Plan
Team Labs and Consultants1-15
be provided with ear muffs/ earplugs. Green belt in and around the mining area will be
developed to attenuate noise and dust impact. The blasting carried out in the mine area will
be carefully planned and executed under the supervision of a responsible officer, to avoid any
accidents. Provisions of rest shelter for mine workers with facility of drinking water supply for
the employees will be provided by the project authority. The standard of the drinking water
will be per WHO guidelines. Periodical training program to inform the employees about their
task, associated risk, and safe working practices will be undertaken. Conduct of mock drill,
Safe storage & handling of explosives. Training will also include information on accident
prevention, proper control and maintenance of equipment and safe material handling
practices. Awareness on safety and ensure using of personal protective equipments (PPE) by
workers. Regular maintenance and testing of equipments will be done. A regular monitoring
of the Occupational Health and Safety will reduce the chances of accidents in the mine.
Records of job related accidents and illness should be maintained. This information will be
reviewed and evaluated to improve the effectiveness of Environmental Health and Safety
program.
Occupational Safety and Health to Control Dust Inhalation
Very little dust is expected to be generated during mining and does not affect the
environment. However while drilling, wet drilling will be practiced. It is a small scale mining
activity and not much vehicular movement is expected. All the above precautions would be
adopted to prevent dust generation at site and to be dispersed in the outside environment.
However, for the safety of workers at site, engaged at the strategic locations/dust generation
points like drills, loading & unloading points 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.
10.1 Occupational Safety and Health to Control Exposure to Noise
There will not be heavy earth moving machinery which may create some noise pollution.
Thus the vibration and noise will be well controlled within permissible limits. To protect the
workers from exposure to high levels of noise, following measures would be adopted:
Provision of protective devices like ear muffs/ear plugs to workers who cannot be
isolated from the source of high intensity noise.
Reducing the exposure time of workers to the higher noise levels by shift management.
Dinesh Granite Exports Environment Management Plan
Team Labs and Consultants1-16
Smooth blasting techniques, special explosives and silent non-explosive demolishing
agent will be used.
Muffed blasting and use of Milli-second detonators will help in reducing the noise
pollution.
10.2 Control of Ground Vibration & Fly Rock generation
It is proposed to use low explosives and less quantity to minimize the effects so that the
vibration generated will be feeble within 8 Hz. General Measures to reduce ground vibration
& fly rocks resulting from blasting are given below:
Mining operations should be carried out in the daytime, as during the night time the
sound intensity becomes higher;
The number of rows in a blast should not be more than four so that fly rock generation
and ground vibration is reduced.
To contain fly rocks, stemming column should not be less than the burden of the hole,
and the blasting area should be muffled;
Each blast should be carefully planned, checked, and executed under the supervision of a
responsible officer.
As per the mining plan, in order to ensure slope stabilization, controlled production blasting
shall be adopted to avoid tension cracks and back breaks. Such cracks may get filled with
water, which reduces the stability of excavated slopes and the angle of slopes.
11.0 Water Quality Management
There is no chemical discharge either from the quarry or from the processing quarry, there
will not be water pollution. The proposed quarry workings will not touch the ground water
aquifer. Quarrying Operations will be carried out on the slope of the Rocky terrain. The
ground water level in this area is 7 m BGL and the quarrying will be done on top of the hill
which is about 95 m above ground level. Maximum depth of quarry is about 15m from top of
hill, flooding by ground water is not anticipated. Hence neither ground water table nor the
general surface drainage pattern is affected Hence there will not be water pollution. There
will be no change in quality of water. However during rainy months, there is a possibility of
wet conditions developing in the working pit this will be minimized, if not altogether
eliminated, by adopting simple techniques like digging trenches all round to drain off
rainwater and preventing surface run off from entering and flooding working pit. The water
Dinesh Granite Exports Environment Management Plan
Team Labs and Consultants1-17
from the pits will be pumped by deploying suitable pumps, if and when required, the mine
drainage can be effectively managed and the pit kept dry to keep up the production
schedule.
11.1 Water Resources
In this area water table is at greater depth of 7 m BGL and the workings are carried out on
top of the hill which is at 95m height. There are no wells or springs in the area. Hence there
will not be adverse effect on ground water due to quarrying. The daily water requirement for
the quarry operations would be approximately 11.1 KLD. Water sprinkling on mine haulage
roads etc shall consume 3.8 KLD. Wet drilling operations consume about 4.0 KLD. For green
belt development water consumption is about 0.9 KLD. Domestic purpose is about 2.4 KLD.
The water is to be sourced from nearby village through tankers. The generation of
wastewater from domestic sources is expected to be approximately 2.0 KLD, which will be
sent to septic tank followed by soak pit.
11.2 Water Management
Following measures will be adopted to mitigate the impact on the water resources:
The blasting activities will have to take care on the sinkholes, cracks and fissures in the
site activities.
During excavation and drilling activities effort must be taken to avoid face collapse at
these cracks and fissures.
To prevent surface water contamination by oil/grease, leak proof containers shall be
used for storage and transportation of oil/grease. The floors of oil/grease handling area
will be kept effectively impervious.
To prevent degradation and maintain the water quality during rainy season, adequate
control measures should be adopted to check the mine run-off into the natural streams.
11.3 Catchment Area Treatment Plan
A catchment area treatment plan has been developed keeping in mind the results of the
hydrology/ hydrogeology of the area and the climate data. As there are no perennial water
sources running on or through the site, the mine water discharge is limited to the monsoon
season only. To keep water from entering the mine during this period, a garland drain will be
developed along the mine’s top bench, which will bend to guide the water to the nearest
natural surface drain. In terms of water quality, good mining practices are planned,
Dinesh Granite Exports Environment Management Plan
Team Labs and Consultants1-18
additionally the natural state of surrounding areas, should ensure that rain water run-off
from the mine does not contain any toxic elements. As the site has no overburden, potential
discharge of sediments is quite limited and any residual particles which are washed down will
be captured by a sump located at the lowest bench. The sump will be cleaned regularly and
discharge water monitored consistently. If required, based on monitoring, an additional catch
pit can be located at the main garland drain. The sump proposed in the bottom bench will be
designed based on the peak discharge and will be expanded over a period of time to
accommodate the increasing quantum of water discharge. Presently, the capacity of the
sump is designed to hold the entire quantum of peak discharge water for more than 10
minutes. The garland drain shall be provided surrounding the mine area. Garland drain and
siltation pond need to be constructed of appropriate size to arrest silt and sediment flows
from soil and mineral dumps. The water so collected will be utilised for watering the mine
area, roads, green belt development etc. The drain should be regularly desilted and
maintained. The garland drain (size, gradient and length) and sump capacity will be designed
keeping 50% safety margin over and above the peak sudden rainfall and maximum discharge
in the area adjoining the mine site. Sump capacity should also provide adequate retention
period to provide proper settling of silt material. The surface water around the mine, and
infrastructure will be regularly tested and appropriate control measures adopted in case of
any pollutant is detected above the prescribed limits.
12.0 Waste Management plan
During this five years operations a total rock mass of 300000m3 will be excavated and 60000
m3 of granite blocks will be recoverable from this rock mass and remaining material of about
240000m3 will go as mineral waste. There is no overburden on the deposit. Boulders are
exposed on top of the colour granite.
13.0 Dump Area
The waste generated during plan period will be dumped in the SW side in the quarry lease
applied area covering an area of 9600 m2 with an average height of 30m. A retaining wall will
be constructed around the dump for preventing the slanting of boulders.
13.1 Land Management
Land degradation is one of the major adverse impacts of opencast mining in the form of
excavated voids and also in the form of waste dumps. Land reclamation plan must, therefore,
Dinesh Granite Exports Environment Management Plan
Team Labs and Consultants1-19
be implemented simultaneously with the mining activities.
13.1.1 Land Reclamation
After completion of mining works, worked out pits will be converted into water harvesting
structure. Hence, no reclamation proposals.
13.1.2 Soil Conservation Measures
The applied area is part of hill raising 95 m above ground level. In quality, the soil existing in
the area is hard and unfertile. Therefore, the growth of trees and plants is uncertain and not
satisfactory. Hence, in this area few small plants and thorny trees are grown here and there.
Except this, no big trees are seen in this area. Top soil, if any will be properly stacked at
earmarked dump site with adequate measures and the same will be used for reclamation and
rehabilitation of the mined out areas. To prevent soil erosion and wash-off of dump-fines
from freshly excavated benches and dumps following measures shall be adopted:
Garland drains will be provided around the mine wherever required to arrest any soil
from the mine area being carried away by the rain water;
Toe drains with suitable baffles will be provided all along the toe of the soil dumps to
arrest any soil from the dump slopes being carried away by the rain water;
Loose material slopes will be covered by mineation by making contour trenches at 3-5
m interval to check soil erosion both due to wind and rain;
Retaining walls (concrete or local stone) will be provided, around the stockpile or
wherever required, to support the benches or any loose material as well as to arrest
sliding of loose debris.
14.0 House Keeping
Proper housekeeping and cleanliness will be maintained in the infrastructure facilities. Wet
mopping will be adopted to conserve water. Sign boards will be provided in the work areas
and the road and building highlighting the safety and occupational aspects.
15.0 Transport Systems
Nuguddi to Tekkali Village road is passing at a distance of 1.0 km in East direction. NH5 is
passing at 2.0 km in SE direction. Nearest town is Tekkali at a distance of 2.5 km in SE
direction. Tekkali railway station is at a distance of 3.0 km in SE direction. The finished
product and waste material is transported by road using trippers. The number of trips will be
approximately two per day for transportation of mineral and the tripper is covered with
Dinesh Granite Exports Environment Management Plan
Team Labs and Consultants1-20
tarpaulin. The lessee will deploy four tippers to transport the finished product, waste blocks,
unfinished and finished blocks from quarry site to yard and trucks to transport sized
dimensional blocks from yard to destination. Cranes will do the loading of blocks. The
materials while transporting do not pose any hazard. Sufficient parking facilities will be
provided for vehicles loading and unloading of material. Safety signs will be displayed inside
and outside the mine to avoid road accidents.
16.0 Environmental Greening Program
Environmental greening program is an important component of the Environment
Management Plan and is an imperative requirement for sink of air pollutants including noise
as per the guidelines issued by the Ministry of Environment and forests, Govt. of India.
Conceptualization, design and implementation of the proposed activity, taking into account
the specific requirement of the proposed mining activity and the site conditions are
presented. Green cover in mining area not only help in reducing pollution level, but also
improves the ecological conditions and prevent soil erosion to great extent. It further
improves the aesthetics and beneficially influences the microclimate of the surrounding.
Phased plantation will be taken up in this area. The plantation will also be taken up at in the
quarry lease area and within 7.5 m buffer zone over an extent of 5000m2. The species that
have history of good survival and growth under similar site conditions shall be planted. The
shelterbelt will contain species, which act as windbreakers so that the environment within
the mine is contained; the planting of different species in rows is envisaged in general in the
greenbelt. A dedicated cell in the mine should be established for post plantation care, which
include, regular watering, manuring, protective measures etc. Diseased and dead plants
should be uprooted and replaced by fresh saplings. Regular monitoring on survival rate and
remedial action should be done in an organized and planned manner.
17.0 Socio-economic Environment
The project provides an opportunity for the local people to get employment directly or
indirectly and helps in the upliftment of the socioeconomic status of the area. The proposed
project would generate an employment of 54. The local inhabitants of the area live in the
villages surrounding the mine area and their main occupation is Agriculture. In a small way
they rear cattle and sheep for sustenance. The mining activity in this belt will benefit the
locals both directly and indirectly. The direct beneficiaries will be those who get employed in
Dinesh Granite Exports Environment Management Plan
Team Labs and Consultants1-21
the mines as skilled and un-skilled workers. The indirect beneficiaries will be those who open
small business to sell goods required by the residents whose “Per Capita” income will be
enhanced by the mining activity, and thereby their purchasing power. In the long run a lot of
social good is expected in the comparatively backward area when the inhabitants will be able
to send their children to school. The change, though slow, is bound to be perceptible. The
management will involve in social activities of stakeholders/surrounding community by
planning the betterment of neighboring social conditions through awareness and welfare
programs to ensure an improved relation, useful in the long run. Many of the beneficiaries of
such programs will include own employees as well. The goodwill of the local populace can
never be ignored. It is proposed to supply drinking water and medical facilities to the villagers.
The management will also support for vocational training and assistance in utilizing
government programs. The channels employed may vary either through direct contact or by
means of local organizations. Another important facet of social environment identified by the
project proponents is a green appearance; hence the management will develop a green belt
towards aesthetic beautification as the same is necessary to be considered as a responsible,
social neighbour.
18.0 Disaster Planning
The mining operation shall be carried out under the management control and direction of a
qualified mines manager holding a Second class manager’s certificate of competency to
manage a metalliferous mine granted by Director General of mines safety (DGMS). DGMS
have been issuing a number of standing orders and circulars to be followed by the mine
management in case of disaster, if any. Moreover mining staff would be sent to refresher
courses from time to time to keep them abreast of the regulations. However following
natural/ quarrying hazards may occur during normal operation
