2.0 PROCESS DESCRIPTION AND SOURCES OF POLLUTION

2.1 Process Description

The choice of mining method has been considered as opencast mining for quarrying the limestone from the mine. The mining operation will be fully mechanized. The sequence of operation is quarrying, drilling, blasting, loading and transportation. All the rock types occurring within the area are fully exposed. There is only top soil that occurs on the surface and hence removal of the top soil by bull dozers would be required. For limestone, 115 mm size drills will be used for drilling. Shovels with bucket capacities of 6.5 m3 and 4.3 m3 shovels. Transportation of limestone from crusher in ML area to cement plant will be by covered belt conveyor system.

2.2 Mineral Reserves

The mineral reserves have been estimated for the limestone horizon only. No OB generation. The weighted average quality of limestone horizon found up to mineable depth is suitable for cement making. The salient features of mine are given in Table-1.

2.3 Anticipated Life of Mine

Anticipated life of the mine is about 50 years.

2.4 Resources Requirement

• Land Requirement

The total mine lease area for mining of limestone is about 631.311 ha which is agricultural land. However, ML area is private (Patta land) land and acquisition is under process. No forest land is involved in ML area. • Water Requirement

The water requirement for the mine machinery operations, dust suppression and afforestation shall be 125 m3/day, which shall be met from the existing allocation for plant & mine of 6180 m3/day water from Kagina river initially and subsequently from water reservoir developed in the mine. • Manpower

The manpower requirement will be about 143 nos. including skilled and unskilled workers.

2.5 Sources of Pollution and Control

Virtually, all surface mining methods for any ore/mineral produce some reversible and irreversible impacts which may lead to changes in the landscape due to large-scale excavation. The environmental pollution due to the opencast mining, in general, could be broadly classified into the following categories: • Air pollution; • Hydrogeological conditions; • Water resources and quality; • Top soil preservation and utilization; • Overburden dump and stacking • Noise levels and vibration; • Land reclamation and rehabilitation; and • Afforestation program.

2.5.1 Air Pollution Mining operations contribute towards air pollution in two ways: addition of gaseous pollutants to the atmosphere and the dust particles. The gaseous pollutants include NOx, SO2 and CO. The sources of pollutants from the mining activity include: • Operation of Heavy Earth Moving Machinery (HEMM) which mostly run on

diesel; • Loading /unloading operations;

(Protection) Act, 1972. Also as cited there are no endangered or rare or threatened plants found in the study area.

4.0 ANTICIPATED ENVIRONMENTAL IMPACTS

The environmental impacts due to the proposed mining project, associated activities like ore crushing have been assessed and adequate management plan has been developed to mitigate the impacts.

4.1 Topography

The applied area is a relatively flat ground with slight undulation and very gentle slope towards East to South East. The surface elevation within the applied area varies from 460 m above MSL towards North-West to 400 m MSL towards South-East.

4.2 Air Quality

Ore loading activities, waste dumping and vehicular movement are the sources to air pollution on the surface. Major activities like drilling, blasting and crushing are sources to air pollution. The trucks plying on the haul roads within the ML area will contribute mainly to dust generation and it is anticipated that marginal increase will occur in the PM level at the mine site. Mining of limestone will be for supplying to captive cement plant by closed conveyor belt system. The air quality predictions have been carried out by using the mathematical simulation model - AERMOD model developed for estimation of fugitive dust due to mining operations. The resultant concentrations are within the permissible limits.

4.3 Noise Levels and Ground Vibrations

With the mining operations, due to machinery, drilling and blasting for mine development, excavation, transportation and crushing of lime stone, it is imperative that noise levels would increase. However, the expected noise levels will not have significant effect on the outside community as habitation area is far away. The blasting operations are proposed to use deep hole drilling and blasting using delay detonators which are bound to reduce the ground vibrations. Further, the ground vibrations will be controlled by using modern shock tubes with delay non-electric (nonel) detonators. In addition various mitigation measures as given EMP will be practiced at the mine site. Hence, ground vibrations will be well within the specified maximum limits.

4.4 Water Resources

Water required to cater the need for drinking purpose, dust suppression at faces and on haul roads, cleaning and washing of HEME, crushing plant and plantation etc. The requirement of water for mining is about 125 m3/day. The source of water supply will be from existing allocation of 6180 m3/day water from Kagina river and water reservoir developed in the ML area. The mine water will be used for spray on haul roads, plantation, cleaning and washing of machineries and toilets etc. No wastewater will be generated after water spraying at faces and along haul roads, for dust suppression. The water gets absorbed by the ground, percolates through porous strata or run down, or gets evaporated. Only the limited quantity of water will be used under high pressure for washing and cleaning of HEME in the work shop/garage. The oil & grease traps will be provided to arrest any petroleum products. This water will be used for plantation, therefore, no recycling of water required in the mine.

Considering the availability of surface water in the area vis-à-vis the consumption, the impact of withdrawal of surface water for various uses mentioned above will be insignificant.

Adequate drainage systems will be planned in the mining, service centre for allowing the water to flow in the pre determined path. The drainage system will be designed in such a way even to meet excess rainfall. No water will be allowed to flow across the waste dumps. However, few check dams will be constructed to arrest wash out from the waste dumps during rainy season. All along the mine roads drainage will be provided and benches will be properly sloped so as to avoid stagnation of water.

4.5 Soil Environment

The environmental impacts of the mining activities on topsoil are based on the quantity of removal of topsoil and its dumping. In the present project, as it is proposed to temporarily store the topsoil and used for plantation schemes, no impact of dozing of topsoil is envisaged. No waste rock generation will be involved.

4.6 Solid Waste

There is no waste handling during the plan period expect top soil. No surface dumping is proposed for the plan period, as there is no waste generation. Hence, no significant impacts are envisaged due to the generation and disposal of solid waste (over burden).

4.7 Flora and Fauna

As per forest records there is no wild life sanctuary and national parks in 15 km radius. There no wildlife corridors in 10 km radius area.

Executive Summary

VIMTA Labs Limited, Hyderabad E-10

As the mining activity is restricted to core zone, no significant impact on the flora of the buffer zone due to the proposed mining is anticipated. With afforestation and development of greenbelt around the mine, the aesthetics will be improved. Extensive plantation comprising of pollutant resistant trees will be carried out surrounding the mine site, which will serve not only as pollution sink but also as a noise barrier. It is expected that with the adoption of these mitigatory measures, the impact due to operation of the mine will be minimal on the terrestrial ecosystem. The incremental dust generation due to the mining and processing operations, at the boundary of the project site are insignificant and it is also expected that with the adoption of mitigatory measures as suggested in EMP, the impact will be minimal on the terrestrial ecosystem and also surrounding area. The impact on the fauna of the buffer zone due to the mining activity will be marginal. The proposed progressive plantation over a period of time will reduce the impact, if any, on the fauna.

4.8 Socio-Economic Aspects

The project will definitely help for the improvement of the socio-economic status of the society in the region by extending the direct / indirect employment opportunities. The project will also increase the development of ancillary and related small-scale industries in the adjoining areas.

5.0 Mitigation Measures

The measures required to be undertaken to minimise the impact of mining:

• Application of Low and Non Waste Technology (LNWT) in the mining process, • Adoption of reuse and recycling technologies to reduce generation of wastes

and optimize the production cost of the mine, and • Progressive land reclamation measures and overburden management along

with the production of lime stone. • The greenbelt shall be developed.

5.1 Environment Management during Operation Phase

5.1.1 Air Pollution Management

Executive Summary

VIMTA Labs Limited, Hyderabad E-11

• Wet drilling shall be practiced; • Drilling machines shall have sharp drill bits for drilling holes; • Blasting should be carried out with optimum charge; • Blasting operations will be carried out as per Circular-no-8 of DGMS rules; • Blasting should be avoided during high winds, night time and temperature

inversion periods; • During high winds, excavation operations should be suspended; • The dumpers should not be overloaded so as to prevent spillage of the ore on

the roads during transportation; • Good housekeeping shall be practiced at all the development and production

benches and at utility service places; and • Good canopy greenbelt shall be developed around the mining area, which acts

as barrier between mining operation and outside mining area. 5.1.2 Noise Pollution Management

The following control measures shall be adopted to keep the ambient noise levels well below the limits: • Blast hole drilling shall be restricted to day time hours only; • Proper and timely maintenance of mining machinery; • Noise levels shall be controlled by using optimum explosive charge per delay

detonators and proper stemming to prevent blow out of holes; • Speed of moving dumpers running in the mine shall be limited to moderate

speed to prevent undue noise as per DGMS circulars enforcing safety standards;

• Provision of user friendly, soft type ear muffs/ear plugs to workers in noise prone zones in the mine;

• The operator’s chamber shall be safely guarded from the noise pollution by preventing it from the noise arising because of the machinery;

• The noise level generated by blasting is only momentary and is about 100-120 dB(A); and

• Developing greenbelt on the sides of crushing plant. Apart from above, the following measures shall be taken to protect the workers from exposure to higher noise levels: • Provision of protective devices like ear muffs/ear plugs; • Provision of sound insulated chambers for the workers deployed on machines

producing higher levels of noise like bulldozers, drills and dumpers etc.; and • Reducing the exposure time of workers to the higher noise levels.

5.1.3 Ground Vibration Control Measures

Executive Summary

VIMTA Labs Limited, Hyderabad E-12

• Proper stemming of holes shall always be carried out; • Blasting shall be avoided during foggy whether and when wind velocity is

more than 25 km/hour; • The burden distance should not exceed 50% of bench height i.e., 5m; • The spacing to burden distance of 5:1 shall be used. • Staggered pattern of blasting shall be adopted; • Shorter stemming lengths of less than 2/3rd of burden distance shall be

avoided to reduce overloading of holes and also to control fly rock; • Maximum number of rows shall be restricted to two since increase in number

of rows results in more confinement of charges in the last rows; • Number of delays used per blast shall be more so as to reduce charge weight

per delay and creation of shock waves. In addition to this, wherever confinement is more, like the corners of the block being blasted, belly holes, etc. extra delay shall be provided. Each line of blast holes shall also being divided to blast at two or more different timings by using delays.

• A delay of 25 milliseconds shall be adopted, as the strata are medium hard with high frequency of jointing/fracturing.

• Blasting operations shall be carried out only during day time as per mine safety guidelines;

• A safe distance of about 500 m from center of blasting should be maintained; and

• During blasting, other activities in the immediate vicinity shall be temporarily stopped.

5.1.4 Water Pollution Management

The control measures to be adopted for controlling water pollution are as follows: • Proper drainage arrangements at mine should be maintained; • Check dams should be constructed where ever required; • De-silting of check dams should be done on regular basis; • Degraded land should be stabilized by afforestation to prevent soil erosion; • Buttress wall and contour trench should be made at the toe of waste dumps

and should be properly maintained; and • Contour bunding at the toe of waste dump should be done before onset of

monsoon. The check dam should have the concrete lining with boulders wrapped in chain link mesh. However the feasibility of constructing new check dams should be studied further for the effective surface water pollution control.

5.1.5 Waste Dump Management

There is no waste generation during the plan period. Hence, no surface dumping is proposed, except top soil generation. A part of the generated top soil will be utilized for formation of bund on 7.5 m safety zone covering an area of 5.00 ha and remaining quantity will be temporarily stacked at southern side of the lease covering an area of 8.50 ha in single terrace of 10 m height. Subsequently, the preserved top soil shall be utilized for backfilling on worked out benches as per requirement.

VIMTA Labs Limited, Hyderabad E-13

A bund of 7.5 m bottom width, 3 m top width and 3 m height will be formed on safety zone of entire applied lease area and this bund will be stabilized with plantation, which will act as protective measure. In addition safety zone on either sides of village road covering an area of 3.50 ha will be maintained as green belt. Backfilling with generated top soil will be carried out on worked-out benches from second five years block period to conceptual period.

5.1.6 Greenbelt Development

The main aim of plantation in and around the mine area is to stabilize the land to protect it from rain and wind erosion. As the leftover working area shall contain broken material and fine particles, stabilization against wind erosion is also a must. The plantation scheme broadly covers the following areas:

∗ Plantation around peripheral portions of mine and other built up structures; ∗ Afforestation of barren areas in the lease hold; ∗ Gardens, parks and haul road plantation; ∗ Plantation by way of reclamation /rehabilitation of mined out blocks;and ∗ Improving the conditions of catchment areas and to prevent erosion.
