1.3 NEED FOR THE PROJECT AND ITS IMPORTANCE TO THE COUNTRY OR

REGION


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


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


Kerala.

Stone will be mined out either by labor or with the help of JCB /

Hitachi.

135m to 100m MSL in conceptual phase.

Considering the stability of rocks the final slope or say ultimate pit

slope is proposed 45° from vertical.

Haul road will be developed up to po int of loading.

Transportation of the mineral from pit -mouth to destination will be

by tippers/trucks (10T capacity).

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.

2.6.6 BLASTING


Kerala.

The blasting design system is properly planned with ideal spacing and burden

patterns, ensuring appropriate stemming column and reduced optimized explosive

charge, so that ground vibratory effects are less, fly rocks, etc are properly regulated

and controlled. The blasting pattern depends on the strata conditions of the rocks.

Since the material in the site is Charnokite which is medium hard to full hard in nature,

it requires drilling and blasting to exploit the same. Since conventional semi

mechanized open cast method of quarrying/mining is done using drilling and

blasting, the same is adopted in this mine/quarry. The drilling and blasting

parameters are as given below.

Depth of each hole : 2.5 to 2.75

Diameter of the hole : 32 mm

App. Spacing between hole : 1m to 1.5m

App. Burden : 0 .6 m to 1m

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.

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.

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.


Kerala.

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:


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.


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:


Kerala.

Disasters might occur only due to natural calamities like earth quake,

excessive rains and flooding etc . To overcome such risks, help/aid would be

sought from emergency services providers like police station, fire station,

hospital, ambulance services from the authorities in the vicinity of the mine

site. Their contact telephone numbers and communication facilities are

provided and displayed on the board at the mine office as well as mine site.

Responsibility of coordinating rescue activities is entrusted to quarry – in –

charge at the quarry site in addition to quarry – in charge is also looking after

statutory obligations under Mines Act, 1952.

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

The awareness of environment has led to the development of

Environment Management Plan including minor development projects , wherein

anticipated impact are assessed and the management plan to mitigate these

impacts has been stipulated in advance. The quarry operations disturb the

landscape involving drilling, blasting, transportation and operation of HEMMs.

Therefore Environmental management of the environment attributes that may

arise due to the quarry project during its operation is very essential and plays a

vital role in mitigating the environmental issues.

The main objectives of environmental monitoring are :-

To assess the changes in environmental conditions,

To monitor the effective implementation of mitigation measures,

Warn significant deteriorations in environmental quality for further Prevention action.


Kerala.

5.0 CONCLUSION

It is anticipated that socio-economic impact due to this project will

positively enhance the raw materials for the developmental concerns and

also may provide ample chances of more employment opportunities for

local inhabitants. There are no Resettlement and Rehabilitation issues and

litigations in any courts of law pending involved in this project. The

project infrastructures can be utilized for the benefit of the local people of

the area. The revenue of the State Govt. will be definitely increasing due

to the proposed activity by means of CRP as well as the processing fee for


Kerala.

appropriate statutory clearances involved in the procedures. The entire

project area is devoid of any endangered flora and fauna as specified in

the IUCN records and the area is total ly far from any other protected areas

under the Wildlife Protection Act as well as the Forest Act. It is proposed

to reclaim the land and develop green cover for eco -restoration with

native species to a maximum extent as far as possible. Thus the proposed

project is not having any possibility in generating untoward changes

which is capable for altering the equilibrium status of the environment or

adjacent ecosystem adversely.
