3.0 Project Description

3.1 General

Quarrying of building stone is not very cumbersome unlike other stone

materials. Generally, with simple machines, it can be excavated and can be

crushed to required size and specification, at specialized stone crushers. In

some cases, even the sized stones are cut to the required size, for usage in

stone masonry works.

The actual block splitting from the sheet rocks or boulders is mainly done

manually or in some cases by semi- mechanized methods, whereas the other

operations, such as removal of overburden, lifting and transporting of cut

blocks, etc. are carried out by mechanized method. The various activities

involved in building stone quarrying are briefed below:

3.2 Method of Quarrying

The proposed method of quarrying to be practiced at the building stone

quarry is of “OPEN CAST” method, by semi-mechanized way. However,

care has to be taken to make it environmental friendly by constantly

adopting suitable mining techniques. The quarrying will be carried-out by

deploying machineries like excavators, air compressors, jack hammers,

tippers etc. The mining techniques being used in the area is in combination of

Jack hammer drilling, followed by excavation method.

3.3 Mining

This is a New Quarry. Quarry shall be done by using semi mechanized

methods in Govt. Gomala Land. The quarry has the approach roads, drivable

in all seasons of the year. Production & development shall be carried with

6.0 Proposed Infrastructure

6.1 General

To carry-out quarrying of building stone, various infrastructural facilities are

is- required for the main activity as well as for environmental protection &

pollution prevention. The basic infrastructural facilities that are required for

the proposed quantity of quarrying are described below.

6.2 Site Services:

Statutory buildings like office building, rest shelters, first aid room, etc. shall

be constructed in a semi-permanent construction using brick walls and tin

sheet roofing. Drinking water is being provided in well-maintained tank near

to the rest shelter. In addition, there will be proper sanitation facilities,

including a septic tank with soak pit, for the discharge of the sewage from

the toilets.

6.3 Facilities for Environmental Management

Generally building stone quarrying is expected to cause air pollution leading

to breathing problems. Activities like drilling, blasting, excavation and

movement of heavy vehicles generate dust and aggravate air pollution in

addition to noise pollution. For mitigating the adverse impacts of the above,

suitable control measures are planned, which are more detailed in the

enclosed Environmental Management Plan.

For activities like drilling, dust suppression etc. water will be required. Also,

for meeting the drinking and sanitary needs of the employees/ workers,

water will be required. For the disposal of the sanitary wastewater (sewage),

septic tank with soak pit is constructed at a suitable place, within close

vicinity of the proposed area.

To take care of the occupational health and safety of workers at site, engaged

at strategic locations/dust generation points like loading and unloading

points, dust masks would be provided. Dust masks would prevent inhalation


P-11

of Respirable Particulate Matter (RPM) thereby reducing the risk of lung

diseases and other respiratory disorders. Regular health monitoring of

workers will be carried out.

The solid waste that is likely to be generated from the proposed activity will

be mainly from the excavation process. This will be in the form of flakes, of

irregular shape. This will be collected and broken into pieces and can be sold

as aggregates for civil works, because of its hard nature.

Most of the area is of sheet rock and the present proposed working is

confined to sheet rocks. Less than 5% of materials are being treated as waste

in this area. The rejected waste material is stacked in the Waste Dump as

shown in the Mining Plan. A JCB will used to remove the over burden from

the surface. When the dump reaches optimum height, suitable greenery will

be grown on this dump to stabilize them.

In addition, as a proactive measure, the following activities will be initiated:

Ø The rainwater accumulating in the work area will be collected and will

be drained-out to the downstream properly with guide drains, so that

it can be used by the downstream fields for their agriculture and allied

purposes.

Ø To avoid soil erosion, rain water entering into the mine pit, carryover

of the material with rain water, suitable garland drains will be

provided all along the active mine area.


P-12

7.0 Rehabilitation & Resettlement (R & R) Plan 7.1 General

The proposed building stone quarrying area, is located near Dodderi Village

of Bengaluru South Taluk & Bengaluru Urban District of Karnataka State.

The proposed site is at about 1.20 kms from the nearest human habitation i.e.

Dodderi Village. In the core area, there are no houses/ hutments etc. Hence

the R & R Plan for the proposed quarry site is limited to the environmental

protection and other social measures planned, as part of the proposed

activity.

7.2 Human Settlements

There is no human settlement in the core zone

7.3 Socio-Economic Benefits

Spurt in industrialization and mining activities have invariably brought a

drastic change in the environment including the society connected with

region. Mostly remote areas tucked away from urbanization and influence of

modern civilization fall within the limits of mine development.

A natural corollary to this the socio economic aspects of the local inhabitants

who have dwelling this region for generations, get suddenly and probably a

radical change, consequent to their abrupt exposure to the mining.

The local people will get employment opportunities, better medical and

educational facilities etc., mainly due to the mining operation from this

project. In addition to this the literacy rate and better living standards shall

increase due to the enhanced earning capacity of villagers.

7.4 Storage and Preservation of Topsoil

There is little soil cover occurring, as the area is exposed with building stone.

Wherever the topsoil generated, shall be collected and stacked separately for

use in afforestation.


P-13

7.5 Reclamation of land

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 mining and also improve the aesthetic

beauty of the area. Due to the Mining activities in this area, the profile of the

ground will change due to formation of pits. At the end of the mining

operations, all solid wastes generated will be used in back filling of quarry

pits in order to bring back original contour of the terrain as for as possible.

The separately stacked top soil will be used to spread over on the compacted

back filled area in order to facilitate the re-vegetation process, which in turn

controls silt flow towards the downstream.

7.6 Environmental Aspects:

The environmental aspects associated with the proposed activity, along with

the suggested mitigation/ control measures are more clearly elaborated in

the Environmental Management Plan.

7.7 Implementation of EMP & Monitoring Programme

The environmental 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 Building Stone Quarry

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.


P-14

8.0 Project Schedule & Cost Estimates 8.1 General

Any developmental activity needs to have adequate resources, be in the form

of man-power or machinery. Careful planning and timely deployment

adequate funds to have the required resources, is of paramount importance

for any successful project implementation. In the following paras, it is

explained about the mobilization schedule of resources and the capital

expenditure estimates.

8.2 Mobilization Schedule

The proposed quarry, being an operating quarry, doesn’t need elaborative

planning for mobilization of man-power, machinery & equipment etc.

8.3 Cost of the Project:

Considering the fluctuating export market scenario and present domestic

market conditions of the products, the cost of the project estimated to be

around Rs. 8 Lakhs, with the concept of outsourcing some of the machineries.


P-15

9.0 Analysis of Proposals & Conclusions:

This upcoming project will meet the development needs of the surrounding

community without causing any negative influence on the environment. It

can be summarized that the development of ’Building Stone Mining‘ will

have a positive impact on the socio-economics of the area and lead to overall

sustainable development of the region.

2.3.2 Raw Materials Requirement

The proposed activity itself is quarrying of building stone, which will be the raw

material for subsequent activities. Hence, there is no requirement of any other raw

materials.

2.3.3 Description of the Process:

In the above mentioned Govt. Gomala Land (Sy. No. 77 (P) of Dodderi Village,

Bengaluru South Taluk & Bengaluru Urban District, Karnataka State), quarrying of

building stone is being carried-out by semi-mechanized open cast mining by using

compressor operated jack hammer drills, excavators, tippers etc. As the rock is exposed

to open sky, open cast quarrying, with controlled blasting will be sufficient.

To achieve the required level of building stone production, it requires 1 Excavator, 1

Compressor, 1 Tractor Mounted Compressor, 1 Tipper, 2 Jack Hammers, 1 Down the

hole ring, 1 Jeep and 1 Water tanker. Transportation of quarried material will be made

through hired trucks to the dispatching points. The flow diagram of various activities

involved in the quarrying of building stone is shown below:

Drilling & Dislodging: The Drilling is carried out in the Quarry by means of

pneumatic methods for development of the quarry and for production of building

stone material. 32 mm dia. Holes are drilled out to required depth for production and

development with a number of holes depending on the spacing and burden. These

holes will be filled with Gun Powder (mild blasting agent) and controlled blasting will

be carried-out to dislodge the stone to the required quantity.

Loading: Loading will be done by using a front end loader by skilled laborers into the

trucks.

CHAPTER 4 ENVIRONMENTAL MANAGEMENT PLAN

4.1 General:

Extracting stone from the earth is an arduous endeavor that affects the local ecosystem

and community on a number of levels. In particular, quarry operations modify the

landscape and topography, and require significant quantities of water and energy.

Additionally, potential occupational health and safety risks exist for quarry employees

and local residents may experience noise and vibrations. The building stone quarrying

activities, can have several environmental impacts such as effects of blasts, vibrations,

stone missiles, loosening of earth thereby increasing the chances of landslides and

siltation rates, aesthetics etc. Also, activities like blasting, cutting, and truck traffic

contribute to noise, vibration, and dust problems for local residents. Responsible site

maintenance, however, can make a remarkable difference in the magnitude of these

impacts as well as the financial burdens that may be attached to them.

The mining development in the study area needs to be intertwined with judicious

utilization of 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 physico-chemical and

biological processes. The Environment Management Plan (EMP) is required to ensure

sustainable development in the study area.

For attaining the desired objective of good environmental quality in the quarry area,

several management strategies in different phases are proposed and evaluated.

Ø Planned improvements including additional control measures

Ø Measures to alleviate problems affecting villages near mining area

Ø Planning for the closure of mines

This section discusses the management plan for mitigation/abatement of impacts and

enhancement of beneficial impacts due to mining. The Environmental Management

Sri. R.K. Prakash


E-10

Plan (EMP) has been designed within the framework of various Indian legislative and

regulatory requirements on environmental and socio-economic aspects.

Environmental problems in building stone quarrying are similar to any opencast

mining operations. The general degradation of land due to unscientific and selective

mining is a common feature. The Environmental Management Plan is presented in

three parts, viz.,

Ø EMP before the Start/Re-start of quarrying activity,

Ø EMP during the operation of the quarry and

Ø EMP at the closure stage of the Quarry

The proposed environmental protection measures, at each of the above stages to meet

the stipulated norms are detailed below:

4.2 Environmental Management Plan before the Start/Re-Start of Quarrying Activity:

Before start/re-start of the proposed quarrying activity, it is suggested to initiate the

following activities, as a pre-cautionary measure for safeguarding the various aspects

of the environment.

4.2.1 Land Environment Management:

It is necessary that while preparing the quarry working layout, optimum land area

should be considered, with requirements for material movement logistics and also

leaving the buffer/ safety zone, as per the legislative requirements. There is a scope for

beautification of the land area within the quarry premises by planting trees, to improve

the aesthetics of the area and also to reduce the pollution outside the activity area.

These aspects are taken due care while preparing the Quarry Plan, which is approved

by the Concerned Government Department i.e. Department of Mines & Geology,

Government of Karnataka.

4.2.2 Green Belt Development:

Plants act as natural sink for variety of air pollutants. These can help to reduce the

pollutant level in the air environment. Locally suitable species shall be selected for

developing the greenery in the quarry area, wherever possible.

4.2.3 Water Environment Management:

During the pre-quarrying stage, adequate arrangements shall be made for meeting the

water requirements of the proposed activity, by way of identifying a suitable and

reliable source of water and also constructing a septic tank with soak pit in the nearby

area, for the usage of the quarry workers.

For the storm water management, all above ground quarries shall be provided with

garland drain with a check-dam to prevent the washing away of silt. This drain shall be

cleaned periodically (at least once in a year). In case of below-ground quarries, suitable

arrangements (in the form of dewatering pumps, DG set etc.) shall be made to dewater

the accumulated water in the quarry pit.

4.2.4 Air Environment Management:

The proposed quarrying activity doesn’t require elaborative air pollution control

measures, at the pre-quarrying stage. However greenery development will be a

positive step towards the air environment management.

4.2.5 Site Security:

Adequate security arrangements shall be made to ensure that the local inhabitants and

the stray cattle are not exposed to the potentials hazards of the quarrying activities.

Compound wall will be built, before starting the Quarrying Activity, along the lease

boundary with locally available boulders, to restrict the entry of unauthorized persons

and other animals into quarry area.

4.2.6 Noise Emission Control:

The proposed quarrying activity doesn’t require elaborative noise control measures, at

the pre-quarrying stage, which can be taken care during the operation of the quarry.

4.3 Environmental Management Plan During the Operational Phase of the Quarry:

During the operational stage of any quarry, it is expected to cause certain pollution on

various aspects of the environment. To mitigate such problems, the proposed

Sri. R.K. Prakash


E-12

environmental protection measures are given below:

4.3.1 Air Quality Management

Generally building stone quarrying is expected to cause air pollution leading to

breathing problems. Also activities like blasting and movement of vehicles generate

dust and aggravate air pollution in addition to noise pollution. Since the proposed

building stone quarrying activity is semi-mechanized with the usage of air

compressors, jack hammers etc., and controlled blasting, the air pollution is minimized

to acceptable limits by strictly following the guidelines promulgated like using wet

drilling, proper maintenance schedules, wrapping the drills with mufflers etc..

However, movement of heavy machinery and trucks using diesel are expected to cause

air pollution and noise pollution. The following measures are proposed to reduce the

impact of these, to the extent possible:

Ø Frequent watering of the haulage road to prevent dust emission due to the

movement of machinery and vehicles

Ø All haulage roads shall be maintained regularly.

Ø Vehicles moving in the activity area shall comply with the prescribed emission

norms to reduce the CO & NOx concentrations

Ø Proper preventive maintenance to reduce emissions

Ø Unnecessary idling of the vehicles and machinery will be completely avoided.

In addition to the above, from the point of view of maintenance of an acceptable

ambient air quality in the region, it is that air quality should be monitored on a regular

basis to check the compliance with the standards prescribed by CPCB and in cases of

non-compliance, appropriate Mitigative measures shall be adopted.

4.3.2 Noise Pollution Control In an operational mine, major noise sources are operation of mine machineries and

equipment, and movement of vehicles, DG Sets etc. Noise generation may be for an

instant, intermittent or continuous periods, with low to high decibels. Periodic

inspection and checks of the risk prone areas and equipment have to be conducted. The

following measures shall be undertaken:

Sri. R.K. Prakash


E-13

Ø Acoustic enclosures, hoods, laggings and screens shall be provided in noise

generating areas to the extent possible so that the sound levels in working areas are

restricted below 85 dB (A) for 8 hours duty. This shall be regulated before engaging

the equipment or purchase of the same.

Ø Provisions of rotation of workers to minimize exposure time as well as provision of

earmuffs to workers exposed to high noise areas are also envisaged.

Ø Green Belt development shall be undertaken around the lease area to minimize

propagation of noise.

Ø Use of sharp drilling bits, delivery of compressed air at optimal pressure and

proper maintenance of compressor, drilling machine, jackhammers and tipper

trucks.

Ø The ambient noise level monitoring shall be carried out in and around the

proposed mine, at regular intervals.

Ø The equipments and machines should be maintained properly. Particular attention

should be given to the silencers and mufflers. Ear muffs or other protective devices

should be provided to the staff working in high noise prone areas.

Ø Unnecessary idling of vehicles and mining equipment shall be avoided.

4.3.3 Water Pollution Control Measures

Generally, building stone quarrying activities are not expected to cause any major

water pollution, unlike other mining activities. However, as a proactive measure, the

following activities will be initiated, as explained in 4.2.3 above

Ø The rainwater accumulating in the work area will be collected and will be

drained-out to the downstream properly with guide drains, so that it can be

used by the downstream fields for their agriculture and allied purposes.

Ø To avoid soil erosion, rain water entering into the mine pit, carry-over of the

material with rain water, suitable garland drains will be provided all along the

active mine area.

4.3.4 Solid Waste Management

The solid waste that is likely to be generated from the proposed activity will be mainly

from the drilling process. This will be in the form of flakes of irregular shape and

Sri. R.K. Prakash


E-14

quarry dust. This will be collected and broken into pieces and can be sold as aggregates

for civil works, because of its hard nature. Quarry dust can be used for road

construction and filling of low-lying areas etc.

4.3.5 Plantation Programme

Under plantation programme, it is suggested to develop green belt all along the

boundary of mine lease area and in the vacant spots, to the extent possible. The

implementation of the development of green belt around the activity area will be of

paramount importance as it will not only add up as an aesthetic feature, but also act as

a pollution sink. But space limitation will be a major constraint, because of the fact that

major portion of the area will be hard rock, where tree plantation is not possible.

However, the following facts shall be considered for greenbelt development, in the

vacant spots, wherever it is possible to take-up the plantation works:

Ø The species to be grown in the areas should be dust tolerant and fast growing

species so that a permanent green belt is created.

Ø 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.

Ø The plantation of any of the above or combination of the above will be decided

in consultation with the local forest authorities and community. In this area

regular watering is required to improve the survival rate.

Ø However, the practice of afforestation programme and other control measures

shall bring greenery to the area and also the vegetation of mixed species and

availability of green cover shall prompt the migration of birds and wild life from

surrounding places.

Plants Species to be planted in the Surrounding Areas:

1. Thespesia pinnata (BUGARI) 2. Butea monosperma (MUTTHAGADA) 3. Madhuca indica (HIPPE) 4. Azadirachta Indica (BEVU), 5. Pongamia pinnata (HONGE) 6. Tamarindous Indica (HUNASE) 7. Ficus benghalensis (ALADA MARA) 8. Hardwickia binata (ANJANA), ,

& other local timber and bio-fuel yielding species. 4.3.6 Storage and Preservation of Topsoil

There is little soil cover occurring, as the area is exposed with building stone. Wherever

the topsoil generated, shall be collected and stacked separately for use in afforestation.

4.4 Environmental Management Plan During the Closure Stage of the Quarry:

The intent of mine closure and rehabilitation is to return the land to as close as is

reasonably possible to its pre-disturbance condition, suitable for use by Traditional

Owners and as habitat for flora and fauna. The Quarry Closure is divided into two

stages viz. Progressive Closure Plan and Final Closure Plan. Generally, the Progressive

Closure Plan will be the part of the approved quarry plan and hence not elaborated

here. Final decommissioning and rehabilitation activities associated with the quarry

closure include the following:

Ø Removal of all infrastructure no longer required at the site. Ø Final site tidy up. Ø Ongoing monitoring and assessment of post-closure rehabilitation.

The proposed process for the final decommissioning for each of the domains is

discussed below. This is a conceptual process at this stage; it will be refined during

closure planning during the life of the quarry.

4.4.1 Site Infrastructure

In general the process for final decommissioning of site infrastructure will be as

follows:

Ø Infrastructure will be removed from site and sold.

Ø Concrete pads will be broken up and either disposed of on site, used as clean

landfill in areas of existing disturbance where the landform is amenable to filing,

or transported off site for disposal in an appropriate clean fill facility.

Ø Topsoil will be spread.

Ø The area will be ripped and seeded.

4.4.2 Office, Rest Shelter and Stores Area

The sheds installed for locating the office, spares parts storage, rest shelter for

employees etc. will be handed over to the local people, for using as an accommodation

for the farmers who will be cultivating the surrounding land.

4.4.3 Hard Rock Pits

These pits will be progressively backfilled and rehabilitated after the year of

completion. The end land use for the completely backfilled pit areas will be a modified

landform with landscape function and vegetation that is resilient, self-sustaining and

comparable to surrounding area. For those not completely backfilled, a void will

remain, it is unlikely that over time these will fill and become permanent water bodies.

4.4.4 Waste Rock Storages

The foremost rehabilitation outcome for the waste rock storages will be to ensure that

the final landform will be stable (physically and chemically). Other desired outcomes

for the waste rock storage areas will be that their landscape function and vegetation is

resilient, self-sustaining and comparable to the surrounding areas.

4.4.5 Access & Haul Roads

The main site access road and haulage road will be left in place, for usage by the

surrounding land owners. This will ensure access to the site for post closure monitoring

works.

4.5 Infrastructure for Environmental Protection

The proposed activity will be under Administrative Control of Quarry Manager, who

will be the overall in-charge for the safety and environmental issues of the activity. It is

proposed to outsource the following activities to specialized agencies:

Ø Collect the information from regular monitoring and create data-base.

Ø Prepare monthly statement

Ø Greenbelt development and it’s maintenance.

Ø Liaison with regulatory authorities like Karnataka State Pollution Control Board

(KSPCB) and other concerned govt. departments on environmental issues.

Ø Monitoring of various environmental parameters (by any MoEF approved lab).

4.6 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. The mitigation

measures suggested above will be implemented so as to reduce the impact on

environment due to the operations of the proposed plant. In order to facilitate easy

implementation, mitigation measures are phased as per the priority implementation.

The priority of the implementation schedule is given below:

4.7 Monitoring Strategy

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 Building Stone will ensure the implementation

of the measures within the mine area and carryout efficient monitoring. Also, the

monitoring of various environmental parameters is necessary, which is a part and

parcel of the environmental protection measures. The proponent Sri. R.K. Prakash, is

committed to implement the monitoring programme, as per the recommendations of

the State Environmental Impact Assessment Authority (SEIAA)/ Karnataka State

Pollution Control Board (KSPCB). In order to implement the measures suggested for

mitigating the adverse impacts on the environment, it is suggested to monitor the

environmental parameters regularly.

4.8 Best Practices in Building Stone Quarrying:

The best practices outlined in this document bring a multitude of advantages to a stone

quarry. These include:

ü Reduction in cleanup costs: Proactive site maintenance over the life of the quarry

reduces the time and money spent on site cleanup when the quarry closes;

reclaiming a well-maintained site is less laborious than restoring one with a poor

preservation plan.

ü Reduction in fuel costs: Reducing machine idling durations, maintaining

infrastructure, and optimizing haul distances reduce fuel consumption and thus

expenses.

ü Avoidance of regulatory penalties: Site organization and proactive hazard

management mitigates potential for occupational exposure and regulatory fees.

ü Increase in employee safety & morale: Employees that feel safe at work are more

likely to make a greater personal investment in the company.

ü Generation of revenue: Site maintenance, interim restoration, and final

rehabilitation can increase land value for future leasing and/or sale.

Additionally, overburden and quarry dust may be sold for use in road

construction and agricultural applications

ü Increased efficiency: A clean and well-organized quarry site can increase

production efficiency by ensuring open paths and roadways, reducing debris,

and increasing the safety of employees.

ü Enhancement of company reputation: Adequate maintenance and rehabilitation

practices can result in greater community acceptance of the quarry and respect

for the company. A company with a reputation for being socially responsible is

likely to retain current customers and attract new ones.

CHAPTER – 5

DISASTER MANAGEMENT PLAN 5.1 General Any of the industrial or mining activities have their associated hazards. If these are

handled properly, there will not be any unwanted damage to life and property.

However, the proposed activity doesn’t involve any hazardous operations and the

magnitude of the operations is also very small. The proposed project is an opencast

mining project. The hazards associated with the proposed activity along with the

mitigation measures, are summarized below:

Hazards Identified Applicability/ Mitigation Measures Roof fall inside the mine v Not applicable for open cast mining Flooding of Rain Water v Escape Routes will be provided to prevent inundation

of storm water v Garland drains with check dam will be provided

Surface Fire v Fire Extinguishers v Sand Buckets v Fire watchers v Fire Check line

Explosives/ Blasting v Controlled Blasting will be carried-out by authorized expert agencies only

Radioactive hazard v Not Anticipated Failure of Pit Slopes v Proper design of bench width and height restrictions. Failure of waste dumps v Restriction of dump height

v Proper slope with plantation Failure of mine benches v Not anticipated, due to the fact that building stone is a

hard rocky mineral Dust v Using water during the drilling operation

v Proper PPE to the workers in the drilling area v Water Sprinkling on Haulage Roads

Noise v Regular maintenance of all equipment v Unnecessary idling of vehicles/ eqpt. not allowed

Transport vehicles v Loading according to the vehicle capacity v All vehicles shall have rear view mirrors v Regular checking of brakes to avoid failures

General Safety Measures v No entry for any unauthorized persons v Quarrying as per Approved Plans only v All statutory requirements will be complied with

Sri. R.K. Prakash


E-20

5.2 Personal Protective Equipment (PPE):

The following PPE will be provided to the persons working in the quarry area:

v Steel-Shoed Industrial Safety Shoes

v Safety Helmet

5.3 Disaster Management Plan

The complete mining operation is carried out under the management control and

direction of a qualified manager. The DGMS have been issuing a number of standing

orders, model standing orders and circulars to be followed by the mine management in

case of disaster, if any. However, following natural/industrial hazards may occur

during normal operation.

v Inundation of mine pit due to flood/excessive rains;

v Slope failures of pit & dump

v Accident due to explosives;

v Accident due to transport & other equipment; and

v Sabotage in case of magazine.

To take care of these hazard, the control measures proposed are given above. The

management is able to deal with the situation efficiently to reduce confusion keeping in

view of the likely sources of danger in the mine.

5.4 Occupational Health & Safety Measures To Control Dust Inhalation

All the necessary 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 strategic locations/dust generation points like loading and unloading

points, dust masks would be provided. Dust masks would prevent inhalation of RPM

thereby reducing the risk of lung diseases and other respiratory disorders. Regular

health monitoring of workers will be carried out.

5.5 Health and Safety Monitoring Plan:

All the potential occupational hazardous work places would be monitored regularly.

The health of employees working in these areas would be monitored once in two years

for early detection of any ailment due to exposure to plant operation.
