1.3 NEED FOR THE PROJECT AND ITS IMPORTANCE TO THE COUNTRY OR
REGION
Granite (Building Stone) Quarry owned by A.Mohammed Basheer atPullampara Village, Nedumangad Taluk & Thiruvananthapuram District,
Kerala.
The major essentiality of building stone is based on its extraordinary compressive
strength and durability (among the hardest, dimensional & structural stones) and it is
having high tolerance towards the vagaries of nature. In construction activities these are
being used because of its hardness & density, durability and strength craft. The proposed
mining project will accomplish its requirement for the construction of buildings, bridges,
paving, monuments and many other exterior projects. Polished slabs and tiles are usually
used in countertops, flooring, retaining walls and landscaping around a center fountain/
pond, staircase and many other design elements (residential and commercial
applications). It is also known as the maintenance-free stone.
The employment opportunities are being created in connection with the quarrying
activities and the local people are being employed for the non technical activities under the
direction of mining engineers and supervisors. For the quarry operations, 30 employees are
being deployed which generates ample opportunities for those peoples indirectly.
Applicant will pay royalty for the mineral produced from the mine, direct and
indirect taxes will be paid thereby contributing to the regional revenue. The public revenue
will further be put for infrastructural development and other sectors like health, education
and social welfare.
1.4 END USE (DOMESTIC/ EXPORT MARKET)
The rock produced from the quarry is transported to the MK Crusher
unit, Irinjium. The aggregate produced is sold to the contractors and to the
consumers which is final ly consumed locally for road (State Highway &
National Highway) & building construction works. Fine Material is also sold
for the utilization for the hollow block/ solid block manufactures.

Method Of Estimation:
The estimation of ore reserves is made by conventional parallel cross
section method using geological cross section. The geological cross
sections are prepared at a regular interval of 50 mts across the strike of
ore body. The area of individual litho units in each and every cross
section is calculated separately. The volume between in the cross section
is arrived on the basis of average the area of parallel cross section i .e,
(S1+S2) / 2 and multiplying sectional interval. And tonnage is arrived by
multiplying by its bulk density.

2.6.2 PROPOSED METHOD OF MINING
It is proposed to undertake Open Cast Semi-Mechanized Mining
Method.
2.6.2.1 Open Cast mining
Granite (Building Stone) Quarry owned by A.Mohammed Basheer atPullampara Village, Nedumangad Taluk & Thiruvananthapuram District,
Kerala.
The mining will be done by open cast semi-mechanized method of mining.
The excavation of mineral is proposed by excavators. The mineral is
fractured and easily exploitable by rock and excavators. The hard strata
are proposed to excavate after drilling and blasting. The bench height and
width will be maintained 5m. Excavated material is transported to the
crusher located within land owned by the project proponent for further
processing. The Mining will be done with the help of tools such as rock
breakers, jack-hammer, compressors, drills , excavators etc. The targeted
annual production of Stone is about 1,01,000 tons/annum.
2.6.2.2 Salient features of mining method
The mining will be done open cast Semi mechanized. The working
will be done by forming benches of 5.0m (Average) height. The proposals
of mining for the next five year workings are given in the table. The Stone
production will be started from the first year by the systematic working
of open cast mines, the main development work will be the forming of
systematic benching. The height of bench will not be kept more than 5.0m
at a time and the width of the benches will be always kept safe according
to provisions. The Mining will be done with the help of tools such as
drills, rock breakers, jack-hammer, compressors, drills, excavators etc.
Subsequent to the drilling and blasting, the materials so dislodged from the
rock mass, the big boulders are subjected to secondary blasting with the help of
jack hammer. There after the material is loaded into trucks or tippers of 10T
capacity with the help of excavator. The loaded material is transported to the
crushing and screening unit for further process.
The cost of the Stone is directly dependent on the size of the material
mined. First Stone bench will be opened by removal of Soil / OB then

2.6.4 CONCEPTUAL MINING PLAN
For any quarry, preparation of conceptual plan amounts to, fore -seeing in
totality and planning for quarrying and relative activities throughout its l ife
span, ti l l such time all the usable minerals are exhausted to the economical
limits and lease area is reclaimed to the extent possible. The norms laid down
by the government agencies from time to time do play important roles.
Therefore preparations of ideal conceptual quarry plan for any quarry is
difficult and such plan prepared remains acceptable only under given
circumstances. I t cannot be over looked that any such plan undergoes
amendments and revisions in the course of progressive stages of exploitation.

ENVIRONMENTAL MANAGEMENT PLAN
BASELINE ENVIRONMENT
The baseline environment quality represents the background
environmental scenario of various environmental components such as
air, noise, land, ecological and socio-economic status of the study area.
Field monitoring studies was carried out by Environmental & Industrial
Research Laboratory M/s METAMORPHOSISS M , Karnataka (both approved
by NABET and Karnataka State Pollution Control Board) to evaluate the base
line status of the project site in compliance with District DEIAA guidelines .
3.1 AIR ENVIRONMENT
The prime objective of the baseline air monitoring was to evaluate the existing air
quality of the area. This will also be useful for assessing the conformity to standards of
the ambient air quality during the operation of the proposed mine. Quality of present
ambient air is within permissible limit. There is no industrial activity in and around the
lease area.
The mining has been proposed by semi-mechanized open cast method. Water spraying
will be done on haul/service roads, mining area, loading and unloading places etc.
There will not be any significant impact on ambient air quality.
Field monitoring studies for 24 hourly frequencies was carried
out to evaluate the base line status of the project site in compliance
with District DEIAA guidelines.

3.2 WATER ENVIRONMENT
There are very few bore wells located near the project site and most of the ground water
source is the open wells, which are mainly used for drinking and agricultural purposes,
however the water samples from the open well at the project site and nearby villages was
collected to study the physio-chemical and biological parameters.
Results & Conclusions: -
Ground water sample were collected in four location including 1 at the project site. The
analysis result of ground water samples at all locations revealed that, all the parameters
are well within the acceptable limits of BIS standards excepting Total coliform.
3.2.1 HYDROLOGY
Based on the observations made in and around the area it was found that
general ground level in this area is 80m above MSL, and the general ground
water table in this area is 15mts below the general ground level (i .e 65 MSL)
during summer and around 10 mts(i .e 70MSL)during monsoon . Since the quarry
falls on the hillock,and the quarry opera tion are restricted up to 75MSL.During
the monsoon the quarry operation are restricted.Hence No quarry operation is
going to touch the general ground water table.
There are no any perennial water bodies within the leasehold area. Apart
from this the water source in this area is mainly storm and ground water. Entire
storm water f lows through the minor watercourses and joins the adjoining
seasonal nallah. The drainage pattern in this area is dendritic in nature.
3.3 NOISE ENVIRONMENT
The main objective of noise monitoring in the study area is to establish
the baseline noise levels and assess the impact of the total noise expected to be

SOCIO-ECONOMICS
Social and demographic profile:Thiruvananthapuram district is characteristically tropical. Heavy rainfall combined with
moderate temperature and fertile soil support luxuriant vegetation in the district. Major agricultural
crops are rice, pepper, ginger, cardamom, rubber and coconut.
The quarrying activity will benefit local villages both directly and indirectly. Direct beneficiary
will be those who get employed in quarry as skilled and unskilled workers. The indirect beneficiaries are
those who are open for small business, comparatively in long run backward inhabitants will send their
children to school.
The state government also will earn revenue in terms of royalty.
Occupational health and safety hazards :
Since the activity of the project involves drilling, rock breaking, loading
and transportation, the primary safety for the workers is the main concern of
the project . Generally personal protective equipments shall be provided to all
individuals inside the quarry lease area.
The secondary safety of workers health shall be also very important for
safe working of the quarry. Sanitation of the quarry area, provision of standard
drinking water, clean system of toilet etc are the first steps to protect spreading
of communicable diseases.
As per the guidelines of DGMS and MMR 1961, i t is mandatory to
maintain the first aid room, first aid kit and also the experts of first aiders.
Accordingly shall be maintained and also the list of first aiders is displaced at
quarry si te. Following measures will be implemented.
Periodical medical checkup programs for all workers.
Compulsory medical checkup program for risk group.
Training for workers regarding occupational hazards. Lung function test for workers exposed to dust.

Historical monuments etc. There are no historical monuments in the coreor buffer zone.
Topsoil & Overburden Management:
More or less entire area is exposed by building stone material only at places,topsoil is visualized which is sparsely distributed. Amount of topsoil exist tothe thickness is just 1mtrs (average). However during the course of quarryingof this area, the topsoi l so occurs will be removed separately and will be usedfor plantation purpose. During the entire life of the quarry about 3500 tonnesof topsoil is l ikely to be generated.
The land use pattern is given below with all details. The road will have width of at least 7m.The details of land area indicating the area likely to be degraded due tomining will be as under: -
Year wise Proposal for reclamation of land.
As the mining will progress, the areas where ultimate pit depth is reached,
backfilling will be started. This will be reducing the transportation of OB and waste
outside the pit area. There is proposal of backfilling and re-contouring during the next
three years of this mining plan. The reclaimed area may also be considered for
plantation to develop green belts. Abandoned pits will be utilized for water storage

during rainy season. This water will be utilized for irrigation and plantation etc. It will
also help in recharging the ground water.
Since the granite rocks are exposed no waste will be generated in the area and as
such no external waste dumping is required. In the mine closure stage, the entire mined
out area of 1.2146 Ha will be reclaimed back with bench plantation / plantation. The
mined area will be properly fenced all around.
It is also suggested to construct a retaining wall where all required and also a garland
drain for collection of rain water at the bottom. Silted water if any will be collected in the
garland drain which in turn will flow into settling pond. Supernatant clear water will be
let out of the area after passing through silt traps.
Afforestation Programme
Plantation will be carried out on the lease periphery, near office, workshop
and haulage roads covering overall 0 .17 Ha by sapling about 350 nos per
year over all during the plan period 0.3433ha will be covered by plantation.
First Six months -- Herbs & grass
Next Six months -- Shrubs
Next Six months onwards -- Trees
Selection of species is based on High Dust Capturing, Soil Holding
Capacity, ground water recharge capacity etc. More focus is given for
medicinal plants.
Plantation along the boundary of the lease area i .e. within 7.5 m barrier
of the lease area boundary has been proposed which will help to improve
the environment and ecology. Plantation will be done around offices,
road side and fencing boundary etc.
Treatment and disposal of water from mine:
Granite (Building Stone) Quarry owned by A.Mohammed Basheer atPullampara Village, Nedumangad Taluk & Thiruvananthapuram District,
Kerala.
Except during monsoon months, no water shall be discharged from
mine. A garland drain shall be made all around the quarry to divert
the water away from the pit through silt settling tank. The rain water
shall be diverted to its natural course.
Measures for minimizing adverse effects on water regime:
It is also suggested to construct a retaining wall where all required and
also a garland drain for collection of rain water at the bottom. Silted water if
any will be collected in the garland drain which in turn will flow into settling
pond. Supernatant clear water will be let out of the area after passing through
silt traps.
Protective measures for ground vibrations/air blast caused by blasting:
The drilling is proposed by jack hammer with 33mm dia. Due to small
diameter hole blasting the vibration in this zone shall not be even
noticeable. The nearest Village Pullampara is situated at about 0.2km
away from the mine. However the measures like monitoring every blast
and use of minimum explosives shall be taken.
Measures for protecting historical monuments and for rehabilitation of
habitat, settlements, disturbed due to mining activity:
There are no historical monuments in the core or buffer zone.
Socio-economic benefits arising out of mining:
It is expected that mining can boost the gross economic production of the
area other than the industrial activities. It provides new avenues of
direct/indirect employment and business. These coupled with growth in
infrastructural facili ties results in improving socio-economic prospects.
Granite (Building Stone) Quarry owned by A.Mohammed Basheer atPullampara Village, Nedumangad Taluk & Thiruvananthapuram District,
Kerala.
The mining in the region will open the gates for Socio-economic upliftment of
the area. People will be getting better facilities of communication and ame nities
due to mining activit ies in the region.
Monitoring schedules for different environmental components after thecommencement of mining operations and related activities
For this quarrying project a quarterly monitoring mechanism for
various environmental parameters shall be evolved if needed as per the
guidelines issued by District Environment Committee.
Waste Management:
Over all about 25,000 tons of solid waste will be generated till the life of
quarry .And about 4,000 tonnes of waste is likely to generate every
year.This waste will be used for road development,fill ing and civil works.
Top Soil Management
A total quantity of 3,750 tons of topsoil is proposed to be removed during
the mining operations. The topsoil excavated from the quarry will be
dumped separately at pre-determined place and subsequently will be
utilized in spreading over reclaimed areas for plantation. Precautions will
be taken to limit the height of the topsoil dump to 5 to 6 meters in order to
preserve its fertility and shelf life. It will be suitably protected from soil
erosion and infertility by planting fodder grass and leguminous plants
during temporary storage.
Safety & Security:
For safety the lease hold areas shall be fenced with proper gates whichshall be guarded by security personals.Disaster Management & Risk Assessment:

Care and maintenance during temporary discontinuance:
Lessee proposes to work cont inuously, till the conceptual stage as
such there is no temporary discontinuance of the mine. All required
actions are timely taken and therefore, we do not foreseen such
discontinuation to occur, however, management is fully equipped up to
overcome any such eventually. However due to unforesee n situation, if
mines happen to discontinue temporarily due to strike, lockout & any
order passed by the government, court and etc, lessee shall take care of
mine by fencing the pit/ quarry deploying the security guards for watch
and ward of the mine.
4.0 ENVIRONMENT MONITORING PROGRAM
