5 1.1 PHYSIOGRAPHY: 1.0 SITE ANALYSIS The lease hold area is a plain ground. The deposit is a sub-surface one with topsoil cover. Major portion of the area applied for lease is covered by soil. The black cotton soil s thickness varies from 0.5Mts to 2.5Mts. The variation in water table in the area is 20Mts to 15Mts, in summer and winter respectively. The area receives rain fall mostly during North-East Monsoon and the average rain fall in about 600mm per annum. The climate is dry and temperature raise up to 41 C in summer and 23 C in winter season. The wind direction in North East-South West and vice versa. They are some active granite quarries surrounding this leased hold area. Fig. 1.1 General View of the Mining area 1.2 REGIONAL GEOLOGY The area forms parts of Quartzofeldspathic belt in the southern part of Tamil Nadu and Geology cab be broadly classifies in to Khondalite and Charnockite groups of rocks. Kondalite grouping this area is essentially made up of calk-granulize, crystalline limestone and garnetiferous sillimanite gneiss, with minor bands of Quartzite. Charnockite group on the other hand including the acid to intermediate charnokite with bands of pyroxene granulite. Both group 4 P a g e SURIYA MINING SERVICES, SALEM, TN

The intrusion of younger pink granite as well as pink migmatitic gneiss and pink augen gneiss. The white garnetiferous sillimanite gneiss while the pink augen gneiss is due to blastic growth of pink potash feldspar augens with in the grey gneiss. A number of minor pegmatite and quartz veins repsent the last stage intrusive activity in the area. The fine/medium grained pink granite gneiss *(with or without garnet) seen in this area as alternate layers (lines) of mafic and yellow/orange/pinkish color forms the beautiful appearance similar to Rawsilk. The tentative geological succession of the rock type is as follow: Topsoil Pegmatite and Quartz veins, pink Fine/medium grained Granite/gneiss Quartz feldspathic granite Peninsular gneiss : Recent : Anchean : Anchean : Anchean : Anchean : Anchean 1.3 GEOLOGY OF THE PRECISE AREA The area applied for lease mainly composed of pink granite gneiss with of without garnet has the fine/medium silky texture and light yellowish pink yellow/ orange color of the rock. The deposit is a sub-surface deposit. The rock strikes North 6 East and South 60 West with steep dip. Strike and diagonal joints are seen. The typical land specimen is light yellowish pink in color with silky texture, fine to medium grained, consist mainly quartz, feldspar and less amount of mafic minerals like biolite mica. Even through the rock type appears has raw type, it s not similar to raw silk type area of Thiruvathvar since, this rock contains more of mafic lines. In few places the outcrops showed grey color of more than the pink/ orange color and looks as grey /granitic gneiss. 5 P a g e SURIYA MINING SERVICES, SALEM, TN

Sub-surface water collection in rainy season is stored in deeper pit in the adjoining area and dewatered with the help of pumps to the natural drainage. 1.5 CLIMATIC CONDITIONS The district receives the rain under the influence of both southwest and northeast monsoons. The northeast monsoon chiefly contributes to the rainfall in the district. Most of the precipitation occurs in the form of cyclonic storms caused due to the depressions in Bay of Bengal. The southwest monsoon rainfall is highly erratic and summer rains are negligible. Rainfall data from seven stations over the period were utilized for analysis and a perusal of the data shows that the normal annual rainfall over the district varies from about 724 to 913 mm. Average rain fall is reported as 812mm per annum. It is minimum around Sathur in the south eastern part of the district. It gradually increases towards west, north and northwest and attains a maximum around Watrap. The district enjoys a subtropical climate. The period from April to June is generally hot and dry. The weather is pleasant during the period from November to January. Usually mornings are more humid than afternoons. The relative humidity is on an average between 65 and 85% in the mornings. Humidity in the afternoon is generally between 40 6 P a g e SURIYA MINING SERVICES, SALEM, TN

8 and 70%.The annual mean minimum and maximum temperatures are and C respectively. The daytime heat is oppressive and the temperature is as high as 40.2 C. The lowest temperature recorded is of the order of 19.3 C Summers The sun is at its glory and shines very brightly during the summers. During the summer months, i.e. from May to June, the temperature varies between 27 deg C and 40 deg C. Therefore, the climate is quite hot. May is the hottest month. Cottons are recommended during this time Winters In winters, which starts from December and lasts till February, the temperature ranges between 20 C and 30 C. The climate remains pleasant during this time, as the temperature rarely falls below 20 C Monsoon Though the rainfall is very frequent and uniform throughout the year, just like the flow of pilgrims and tourists, the city receives the major share of rainfall between the months of July and October. The average rainfall is 85 cm. Fig. 1.3 Monsoon Forecast 7 P a g e SURIYA MINING SERVICES, SALEM, TN

Study on occupation characteristics of population should analyze the workforce engaged in different type of occupation. Cultivators are the major category of occupation representing the workforce owning land. Subramaniyapuram village had total cultivators 274 (20.16% of the total workers) cultivators. The proportion of cultivators to total workers is calculated as a percent for the two census years 2001 and 2011 for the taluk of Sivakasi in Subramaniyapuram village. There were about 162 (24.43%) men in 2001 which is decrease 58 (10.84%) according to census Subramaniyapuram village had female cultivators 112 (16.09% of the female workers) cultivators during 2001 census which is decreased 33 (7.14 %) during according to census The distribution of agricultural laborers in the study area for the two census periods has revealed that the study area has experienced a decline in the proportion of workers classed as agricultural laborers between 2001 and Sivakasi taluk in Subramaniyapuram village had agricultural labourers 307 (22.59 % of the total workers) agricultural labourers during census There were about 153 (23.08 % of male workers) men in 2001 which is decrease 7 (1.31% of male workers) according to census years Subramaniyapuram village had female agricultural laborer decreased 5 (1.08%) census 2011 compare to the previous census year 2001 about 22.13% of female workers. This group includes the employment of workers in manufacturing activities. Agro based industries, located in the study area engages a sizeable amount of workers. The distribution of secondary workers in the study area is calculated as percent to the total workers. 13 P a g e SURIYA MINING SERVICES, SALEM, TN

15 The proportion of secondary workers to total workers has experienced decreasing trend in the Subramaniyapuram village area between 2001 and Secondary workers during 2001 and 2011 it could be stated that this may be due to the opening of a number of manufacturing units in the study area. The tertiary workers include the labour force engaged in service sector such as education, medical, judicial, finance, administration, recreation, trade and commerce and transport. In Subramaniyapuram village had tertiary workers accounted for about percent of the workers during 2001 census it is increased 74.82% according to census There were about male tertiary workers of 328 (49.47% of the male workers which is increases 430 (80.37% of the male workers) according to census There were about 408 women tertiary workers (58.62 % of the female workers) during 2001census which is almost equally increased to (68.40 % of the female workers) according to census The study area has experienced a change in the occupational structure in the form of a decline in the proportion of cultivators, agricultural laborers and an increase in the proportion of tertiary workers.

17 2.0 EVALUATION OF IMPACTS Opencast mining activity causes some adverse impacts on the surrounding environmental unless proper environmental management plan is adopted. Selecting suitable sites for mining and adopting the guidelines prescribed by the Ministry of Environment, Forest & Climate Change (MoEFCC) and Indian Bureau of mines (IBM), one can minimize the major possible impacts. In this chapter, an attempt has been made to quantify the possible environmental impacts on various features such as air, water, noise, land, ecology and socio-economics. The following aspects have been studied to identify the possible impacts while achieving the total production of 100 cum/year of colored Granite. The magnitude and significance of the environmental pollution caused by mining depends on method of mining, scale and concentration of mining activity. 2.1 AIR ENVIRONMENT Mining is carried out by open cast semi mechanized methods using jack hammer drilling & wire saw cutting and using low explosive blasting. Based on the various operation involved in the production of minerals, the various emission sources has been identified as given below. a. Point sources b. Area sources. c. Line sources. Drilling operation of the mine is considered as point sources. Extraction of minerals from mine, are considered as area source. Transportation of materials from mining benches to various end points is considered as line sources. The impacts of above sources on air environment are discussed below. a) Drilling & blasting The concentrations due to low explosive blasting will be confined to a maximum distance of 10m from the area of blasting. These concentrations will not emit 16 P a g e SURIYA MINING SERVICES, SALEM, TN

18 continuously. However presence of personnel near the blasting site during blasting will be totally avoided. So, the impacts of blasting on the air environment will be minimal. b) Extraction & loading: Extraction & loading will be done by a crane and excavator and these activities of mine operation is contributing to the area source emission and the extend influence of this operation is about 100m 2 c) Haulage & transportation In this operating mine, the dressed block form face to the consumers is transported by hired trucks. The trucks will be well maintained so that exhaust smoke does not contribute abnormal valves of noxious and unburnt hydrocarbons. The other sources of air pollution are due to the dust generated during the movement of tippers on the haul road. The above source, which includes drilling, low explosive blasting excavation, and haulage for transport of blocked, will contribute to dust pollution in the air ANTICIPATED IMPACTS The impacts envisaged due to mining activity are evaluated based on various factors the emission inventory of the pollutants is as follows, the main air pollutant would be dust or particulate matter generated by handling and transportation of colored granite. But the impacts of mining operation on air quality is minimum as mining involved methods by using jackhammer drilling & wire saw cutting & low explosive blasting and as the production quantity is very less i.e.0.4 Cum/day only. The maximum concentration of particulate matter (PM 10) recorded in mine lease is 34µg/m 3. The envisaged production of minerals is only 0.4 cum/day. Prediction levels of PM10 were found to be within permissible limits. Anticipated impacts is assessed by considering increase of 10 % in core zone on the PM10 levels due to the mining operation and the following table shows the overall scenario. The dust generated due to mining operations will be controlled by water sprinkling through water tankers. 17 P a g e SURIYA MINING SERVICES, SALEM, TN

19 OVERALL SCENARIO Particulars Baseline concentration 34 Predicted concentration 3.4 Overall scenario 37.4 Specified NAAQ Limits 100µg/m 3 Concentration (µg/ m 3 ) Core Zone 2.2 NOISE ENVIRONMENT Noise will be produced at the mine is due to operation of machinery, drilling blasting, and movement of vehicles. The noise generated by the mining activity is dissipated within a small zone around the mine. There are no major impacts of the mining activity in the vicinity however; pronounced effect of above noise levels will felt only near the activity working area and on the personnel working in the vicinity. The impacts of noise on the village are negligible as the villages are located far from the mine site. 2.3 WATER ENVIRONMENT The water regime is unpolluted by any external source, quarrying will not have any impact on water regime IMPACT ON SURFACE WATER There are no major streams and rivers, which can get affected by the mining. Hence there will be no effect on the surface water. During the plan period quarrying will go to depth of 8 meters from the present level of mining. During the monsoon period, the rainwater, if gets stagnated, will be drained out. The benches will made with an inward slope to facilities run off faster on to the mine floor. Small bunds, garlands and silting tanks also will be constructed to minimize inflow muddy water which carries fine materials. 18 P a g e SURIYA MINING SERVICES, SALEM, TN

20 2.3.2 IMPACT ON GROUND WATER the ground water regime. Mining activity will be above the BWL (20m). Hence, there will be no effect on IMPACT ON WATER QUALITY Water quality in the buffer zone has indicated that the ground water is free from heavy metal concentration and these mining activities will not interference on the water quality. There is no generation and discharge of waste water from this mine. 2.4 LAND ENVIRONMENT Various components of land environment have been identified for study fo impacts mine operations. Details of the same are given below: SOLID WASTE GENERATION Removal of weathered rock and the rock waste is the only solid waste that will be generated from this mine. Some of the materials from the waste may be sorted out and used for making small blocks to be used by the local unit for making tiles. The markets for tiles are good at the moment and they will offer a better substitute for marble in terms of price and quality. Some rejected and unsorted materials may be used in the civil engineering projects in the vicinity of the area. The waste materials can also be crushed into smaller sizes and can be used as road metal. The waste generated during the five years dumped in the zone separate reserved for during within the Q.L. area. The dump is designed in such a way that it will have slopes equal to the angle of repose of such materials. Garland drains have to be sunk along around the leading edge of the dump. A retaining wall will be constructed around the dump to preventing the slanting of boulders care will be minimizing the waste generation at the source. About 608 m 3 /Year of waste will be generated from this mine. The topsoil, weathered granite and granite waste will be dumped along the boundary southern side of the lease hold area (safety zone). 19 P a g e SURIYA MINING SERVICES, SALEM, TN

21 2.4.2 IMPACT ON LAND USE The mine is located in an area of 2.980Ha.No forestland is involved. It may not be possible to complete regain the original topography of the area. During quarrying whatever solid waste is generated shall be dumped at dumping site in outside the Q.L. area. The mining lease area is not a part of any type of forest. Entire mine lease area is govt. land hence all the impact on land use is positive because aesthetic environment will not be effected, as the mine is located on a plain with some bushes. There is no forest area located within 10km from the lease boundary. Due to opencast mining activities, the landscape will be slightly changed. There will be no land subsidence as the country is made up of hard rock. The soil cover in this mine is almost nil and agriculture is seen mainly in the plains in the vicinity of the lease area and the mining will not have any impact on the agricultural pattern. Only few bushes will be cleared to facilitate mining and other related activities and there are no big trees, which may have to be cut IMPACT OF GROUND VIBRATION Fragmentation of rock by blasting is an important operation in mining project, where hard rock occurs. Blasting will be done only when it is absolutely necessary, using low intensity explosives. Blasting of the minerals at the proposed mine will be done by using lowdensity chemical explosive like ECM/CaOH will be used. Sometimes smooth blasting may be done using silent non- explosive demolishing agents like Acconex. The ground vibration caused by blasting will not have any affect as the mining is on a mound and the vibrations will be minimum and will not be carried too far due to the hard nature of the rock. 2.5 BIOLOGICAL ENVIRONMENT There is no adverse impacts are anticipated due to the proposed mining activity on biological environment. However with the implementation of the environment management measures, there will be improvement in the parameters of biological environment. The tree species found with the core zone represent the common type of flora species along with small shrubs and bushes. Due to mining activities community structure of the 20 P a g e SURIYA MINING SERVICES, SALEM, TN

22 vegetation will not change, whereas diversity of plant species and food web index of the area compared to the existing level. 2.6 SOCIO ECONOMIC ENVIRONMENT It will be obvious to assume that the activities of the mining operation have to be produced some improvement in the socio-economic levels in the study area. The lessee will provide employment to local population and it will give preference to the local people whenever there is requirement of manpower. The proposed mining activities will provide employment to persons of different skills and trades. The local population is the largest plausibility among these employees. The employment potential ameliorated economic conditions of these families directly and provided employment to many other families indirectly who are involved in business and service oriented activities. This in-turn will improve the socio-economic conditions of the area. 2.7 OCCUPATIONAL HEALTH AND SAFETY The mine is going to be developed mainly semi mechanized opencast method by using jackhammer drilling, wire saw cutting & low explosive blasting. No major crushing or pulverization will be done here. The small- scale mining will not have any ill effects on labour. Excessive dust and noise are the chief health hazards for the miners. As already mentioned these causative factors are well within the safety limits and the proponents will strictly implemented the prescribed safety measures. The health of the workers will be regularly checked and suitable medical facilities should be created on or close to the site. Highest safety will be ensured in the working conditions of the miners. 21 P a g e SURIYA MINING SERVICES, SALEM, TN

23 3.0 ENVIRONMENTAL MANAGEMENT PLAN The mining development in the study area needs to intertwine with judicious utilization natural resource within the limits or permissible assimilative capacity. The assimilative capacity of the study area is the maximum amount 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 physio-chemical and biological processes. The environment management plan (EMP) is required to ensure sustainable development in the study area. This section discusses the management plan for mitigation/abatement impacts and enhancement of beneficial impacts due to mining. The environment management plan (EMP) has been designed within the framework of various Indian legislative and regulatory requirements on environment and socio-economic aspects. Environmental management plan giving the environmental protection measures at mine to meet the stipulated norms of IBM/MoEF&CC are as detailed. 3.1 AIR POLLUTION CONTROL MEASURES The present ambient air quality measurement in the mine area are well within the limit due to the proposed production of 100 Cum/Year of colored granite, there will be marginal increase in dust concentration. Mitigative measures suggested for air pollution control are based on the baseline ambient air quality monitoring data. From the point of view maintenance of an acceptable ambient air quality in the region, it is desirable that air quality should be monitoring on a regular basis to check the standards prescribed by CPCB and in cause of non-compliance appropriate mitigative measure shall be adopted. The following dust prone areas are identified for adopting control measure in the mine area. 1) Drilling & wire saw cutting blasting 2) Excavation 3) Transportation 22 P a g e SURIYA MINING SERVICES, SALEM, TN

24 The environmental control measures which will be implemented to control the fugitive dust release from the proposed production are given below: Wet drilling system & dust proof Optima wire saw cutting ( using water - reduces dust ) Use of sharp drill bits for drilling holes. The charge concentration of the explosive will be between grams per linear meter. Water sprinkling arrangement such as specially fabricated tankers mounted in tipper are deployed at mine site to control; the fugitive dust generation from the haulage roads. Regular grading of haul roads service to clear accumulation of loose materials. The blasted blocks (Temporary) are wetted by spraying water. Avoiding blasting during high windy periods, times and temperature inversion periods. Excavation operations are suspended during periods of very strong winds. Massive afforestation for control of dust. Spraying of water on sub grade stacks. The vehicle and machinery are kept in well maintained so that emission of fugitive constitute is minimized. Plantation of wide leaf trees, creepers, tall grass around working pit, along roads will help suppress dust. Tall trees with an average height of 5m will be developed all along the boundary of the lease area to minimize the dispersion of the dust from the mining. Periodical monitoring of air quality to take steps to control the pollutant OCCUPATION HEALTH & SAFETY MEASURES All the precautions would be adopted to prevent dust generation at site and to be dispersion into the outer environment. However, fir the safety of workers at site, engaged ay 23 P a g e SURIYA MINING SERVICES, SALEM, TN

25 strategic locations/ dust generation points like drilling, loading and unloading points, etc. dust masks would be provided. Dust masks would prevent inhalation of RSPM thereby reducing the risk of lung disease and other respiratory disorders. Regular health monitoring of workers will be carried out. 3.2 NOISE POLLUTION CONTROL MEASUREs The ambient noise level monitoring is carried out in and around the proposed mine shows that ambient noise levels are well within the stipulated limits of CPCB. Noise generation may be for an instant, intermitted or for continuous periods, with low to high decibels. Periodic inspections and checks of the risk prone areas and equipment have to be conducted. will be practiced. To control noise pollution during the proposed mining operation following steps The noise generated by the machinery will be reduced by proper lubrication of the machinery and equipment. The workers employed should be provided with personal hearing protection equipment, with earmuffs and earplugs combined, as a protection from the high noise level generated at the plant site. The provision of green barrier along the boundary will further reduce the propagation of noise level generated. Limiting time exposure of workers to excessive noise. Speed of trucks entering or leaving the mine is limited to moderate speed of 25 kmph to prevent undue noise from empty tippers SAFETY IN BLASTING Care should take to evacuate the mining area completely at the time of low explosive blasting operations. The blasting team should be equipped with all personal safety and precautionary measure. The following safety measure will be attention while conducting the blasting operations. 24 P a g e SURIYA MINING SERVICES, SALEM, TN

26 A blasting SIREN should be used at the time blasting audio signal Before blasting and after blasting, red & green flags should be displayed as visual signals. Warning notice boards indicating the time of blasting and NOT TO TRESPASS are displayed prominently. 3.3 WATER POLLUTIN CONTROL MEASURES The action program for minimizing adverse affects on water regime is to prevent wash-off of mine water and uncontrolled run-off water during monsoon. Proposed measures for this are as follows: a) Building/extending of retention/toe wall at the foot of the dumps. b) Construction of garland drains along the slops to divert the rainwater course away from the dumping areas. c) Covering of dump slopes with grass plantation to stabilize and prevent erosion. d) Plantation of trees along the rides and slopes. 3.4 LAND ENVIRONMENT STORAGE AND REUSE OF TOP SOIL: Topsoil removed during clearing of the area for granite extraction shall be stacked separately to check the erosion of the stacked soil. A retaining wall shall be constructed all around the topsoil stockyard. Planting of grass and local species etc. are proposed on the surface of this stack to prevent erosion and to increase the soil nitrogen. As per the analysis of the soil samples they are found to be basic in nature. During afforestation, it is recommended to plant fast growing species with good quality canopy cover and dense leaf density and some ornamental species to give a good aesthetic look. It is recommended to sow neem, mahogany plants as soil and climate conditions are suitable for the growth of these plants SOIL WASTE MANAGEMENT Removal of weathered rock and the rock waste is the only solid waste that will be generated from this mine. Some of the material from the waste may be sorted out and used for making small blocks to be used by the local unit for making lines. The market for tiles is good at 25 P a g e SURIYA MINING SERVICES, SALEM, TN

27 the moment and they will offer a better substitute for marble in terms of price and quality. Some rejected and unsorted material may be used in the civil engineering projects in the vicinity of the area. The waste materials can also be crushed into smaller sizes and can be used as road metal. The waste generated during the five years dumped in the zone separately reserved for dumping within the Q.L. area. The dump will be designed in such that it will have slopes equal to the angle to the repose of such material. Garland drains have to be sunk along around the leading edge of the dump. A retaining wall will be constructed around the dump to preventing the slanting of boulders care will be taken to minimize the waste generation at the source. About 608 m 3 /Year of waste will be generated from this mine. The topsoil, weathered granite and granite waste will be dumped along the boundary southern side of the lease hold area (safety zone) Stabilization of dumps Land restoration or reclamation of the area is very essential in any mining industry. Proper measure adopted during restoration will control most of the adverse environmental impacts of quarry and also improve the aesthetic beauty of the area. Due to the quarry activities in this area the profile of the ground will change due t formation of pits. At the end of the quarry operations, the top soil/minerals rejects will be utilized for back filling wherever suitable and rehabilitation. Following steps shall be taken for improving and protecting the environment. A) Quarry lease area. B) Surrounding the quarry lease area. C) Surrounding the statutory building. D) On the undisturbed virgin lease area. i. Surrounding the mining area The dust generated during the quarrying operations will be carried by wind and will be deposited over the trees and on the adjacent area around the quarry in the buffer zone. To filter this dust, a green belt of 10m width shall be developed along the quarry lease area i.e., around ultimate pit limit. This green belt will also act as sound barrier. In between the lease tree 26 P a g e SURIYA MINING SERVICES, SALEM, TN

28 saplings, grass and bushes shall be grown. Creation of the green belt around the lease areas shall be undertaken on priority basis and shall be completed concurrent to quarry over a 10-year period. ii. Surrounding the statutory buildings All around the proposed statutory buildings and along the road side trees shall be planted in addition to the existing ones which will, protect the workers from the noise and dust. To plant trees around the statutory buildings, the topsoil that is going to be mined from the area shall be laid to form a strip of 10-15m width and 0.5m thickness. iii. On the undisturbed virgin lease area The undisturbed virgin lease area shall be utilized for afforestation purposes by developing the area with local varieties. This work shall be done after the cessation of quarry operations. iv. Afforestation plan The topsoil and weather granite will be stored separately and the same will be spread on the boundary safety zone. Trees like neem will be planted at a rate 10 tree per annum and rate of survival expected to 80% in this area. Table 3.1 Showing programme of year wise afforestation of the five year period.
