1.4.0 REVIEW OF MINING PLAN: 1.4.1 Name of the Quarry : Iruthukottai Black Granite Quarry Name of quarry Owner : Thiru. R. Vishal Chahal, Address : D-1, Sraddha Green Meadows, 4th Cross Rustan Bagh, District : Bangalore 560 017, State : Karnataka Phone No : +91 94434 44888.
1.4.2 REVIEW OF COMPLIANCE POSITION OF SALIENT FEATURES OF MINING PLAN All the conditions stipulated in the G.O and lease deed was fulfilled and maintained during the course of quarry operations.
1.5.0 REVIEW OF IMPORTANT CHAPTERS OF MINING PLAN 1.5.1 EXPLORATION: The Geological Survey of India and Department of Geology and Mining have already carried out mapping and by the well experienced geologists. No detailed prospecting was carried out by any agencies. The black granite is clearly visible from the surface outcrops and the RQP and his team members had carried out mapping and clearly demarcate the black granite deposit of the area. Hence, no bore holes were proposed to drill during the mining plan period. Based on these features, estimation of geological resources, Mineable reserve is arrived at considering waste products and market potentiality.

Scheme of Quarrying Iruthukottai Black Granite 1.5.2 QUARRY DEVELOPMENT The quarry development has proposed and the actual production in the Mining plan is given table below. During the approved mining plan period the quarry development and production was proposed on the southern side and progressing towards Northern side with the dimension of 55m (L) X 34m (W) X 8m (D). The production and development for the Mining plan period is given under.
PROPOSAL GIVEN THE MINING PLAN PERIOD: Table - 3 Proposed Achieved Year ROM Production Production achieved (m3) @ 5% (m3) (m3) 2010 – 11 1000 50 Development work 2011 – 12 2,000 100 94.238 2012 – 13 2,000 100 289.326 2013 – 14 2,000 100 228.722 2,000 100 Development work 2014 – 15 (Upto 02.03.2015) Total 9,000 450 612.286
Recovery anticipated 5% and recovery achieved around @ 4% due to weathered joints and fractures of top layer of the deposits. There was no substantial change in the proposed and actual productions during the approved mining plan period. The Black granite recovery percentage has been reduced in surface levels and in deep seated conditions it may enhance the recovery upto 30% from the R.O.M. due to absence of weathered joints, fractures also following reasons. 1. During the plan period the lessee has deployed drilling and blasting method of mining, at present the new innovative machineries like diamond wire saw cutting method has been adopted for quarrying operation. The diamond wire saw cutting does not produce any vibration during cutting of the granite dimensional stone from the parent rock mass and there is no chance to generate such cracks or fractures. Hence, the diamond wire saw cutting method has given the additional recovery of granite than the previous method of mining. 2. The geological factors are more importance for recovery of granite dimensional stone quarries. Due to geological factors like structure, texture, colour, Mineral content, etc., has decided to recovery percentage. In the surface level of the granite body may contain inclusion of country rock, patches, joints and cracks. at present depth there are no patches, country rock inclusion and any contamination of the granite formation of this quarry is observed. These textural features can be found only after removed the top layer.
3
Scheme of Quarrying Iruthukottai Black Granite At present the lessee had developed the top layer and find out the potential area for removing black granite by economically safe and systematic quarrying. Hence, the above projection we have considered an average recovery of 30% during the present scheme period, it may enhance. In the interest of quarrying, the lessee worked out continuously and tried his maximum effort to market. The lessee has keen in carrying out the quarrying operations in a scientific and systematic manner to win the Black Granite in all possible means.
1.5.3 REVIEW OF MINING DEVELOPMENT: The quarry development and production was not carried out as per proposed in the mining plan period. During the plan period the quarry development and production proposed to carry out on the southern side and progressive towards Northern side. But the lessee carried out the quarrying operation on the eastern side due to the lessee has identify the good quality of marketable black granite is observed on the eastern side during development work. Hence, the lessee started the quarry work on the eastern side and at present most of the area had developed with the maximum dimension of present pit is 130m (L) X 59m (W) X 19m (D). In the interest of quarrying, the lessee worked out continuously and tried his maximum effort to market. The lessee carried out all possible ways and best efforts to develop and exploit the granite continuously.
1.6.0 AFFORESTATION PROGRAMME: Program of Afforestation as given in the Mining plan period are given as under. The safety distance along the western boundary barrier has been identified and utilized for topsoil dumping and afforestation. Proposal given in the Mining Plan: Table- 4 Expected Place No of Type of Year Survival saplings sapling rate % 2010 - 11 30 80 Lease boundary 2011 – 12 30 Aylanthus, Neem, 80 Lease boundary 2012 - 13 30 Tamarind and other 80 Lease boundary 2013 – 14 30 Regional trees 80 Lease boundary 2014 – 15 30 80 Lease boundary
Total number of trees planted during the mining plan period is around 150 numbers along the safety barrier an expected survival at the rate of 80%. The afforestation program carried out during the Mining plan period is affected by the failure of monsoon and water scarcity. Anyhow, the lessee ensures to compensate the afforestation during the present scheme period. 4
Scheme of Quarrying Iruthukottai Black Granite 1.7.0 LAND RECLAMATION AND REHABILITATION: Due to nature of occurrence of the granite body in this quarry is beyond the workable limits. During the approved mining plan period the quantum of waste is proposed about 8550m3 (Granite Rejects) the same was proposed to dumped in the eastern side with dimension of L 40m x W 21.37m x H 10.0m and excavated topsoil (3750m3) are proposed to dumped on the safety barrier and utilized for road and afforestation purpose. Dumps are properly terraced systematically by multi-level dumping. When the dump becomes inactive part of the excavated topsoil will be preserved over and sides of the waste dump and planting tree sapling for increasing the stability of the waste dumps and to prevent erosion during rainy season. During the Mining plan period 14m(2m Topsoil + 12m Black granite) depth has been considered as economically safe and scientific quarrying, now the quarry attained a maximum depth of 19m. During this scheme period 32m depth has been considered as economically viable for safe and systematic quarrying at present market scenario. Immediate backfilling does not arise. When the quarry reach the ultimate pit limit or at the end of life of quarry, quarried out waste will be backfilled.
1.8.0 CONTROL OF DUST, NOISE AND VIBRATION: The quarrying operation was carried out by semi mechanized means and HEMM were deployed occasionally. Hence, the effects due to dust, noise and vibration were minimal.
Anyhow the Ambient quality of Air respect of dust concentration, respirable dust, SO2, NO2 were tested periodically for every season around 1 kms radius for core and buffer zones as per the guidance of TNPCB. The dust prone areas of the Quarry are Blasting site, Loading, Hauling and dumping. All such areas were closely monitored as per the guidelines. The quarry operation was carried out by semi mechanized method with drilling and blasting. Dressing carried out manually with portable compressor and Jack Hammers. Hence, the effects due to dust (only development and bench formation), noise and vibration were minimal.
NOISE: The ambient Noise Level ranges must be <80 dB. As the compressors are, keep at high levels the impact of noise to the workers is less. Expanding Chemical is used for cracking the rough blocks and therefore noise of blasting is minimal.
VIBRATION: Blasting induced ground vibration is the only source of vibration in quarrying area. Since chemicals @ 1kg for 3 feet is used for 8 hours retention time for cracking the solid rock along the line of drilling. Vibration is observed in this quarry is negligible.

The area lies between the Latitudes of 12°27'57.81"N to 12°28'01.75"N and Longitudes of 77°47'50.28"E to 77°47’55.63 in WGS Datum-1984 (Refer Plate No. I & IA).
3.0 EXPLORATION AND RESERVES a) Physiography The area is generally exhibits an undulated terrain. The general gradient towards southeast and the altitude of the area is 875m (max) above from MSL. The black granite mostly covered with reddish soil. The Dolerite dyke is intruded between the batholithic formations of Biotite Gneiss. The area receives rainfall 750 - 900mm /annum and the ground water occurs at a depth of 52m in summer and 48m at rainy season.
Topographical View of the Iruthukottai Black Granite (Dolerite) Quarry Lease Area
7
Scheme of Quarrying Iruthukottai Black Granite b) Regional geology The hard rock terrain of Achaean to late Proterozoic groups comprises of predominantly Charnockite, Khondalite group of rocks and their magmatic derivatives, supracrustal sequences intruded by ultramafic complexes, basic dykes and granites. Granites were formed from molten rock referred to as “Magma” formed at great depths within the crust of the earth. During the cooling process, some of the minerals grow into larger crystals of colours peculiar to those minerals or get aligned along certain preferred directions giving rise to beautiful colors and patterns. Such rocks that were formed at great depths during the Archaean age are now exposed at the surface of the earth as a result of the combined actions of wind, air, sun and water and weathering and denudation over the past several million years.
c) Geology of the area. The area for quarry lease contains pre-existing rock of Biotite Gneiss and intruded by dolerite. The dyke is covered by 2m thickness of topsoil followed by fresh marketable black granite. The dyke rock is hard, compact and sheet in nature at the middle and boundary along the contacts due to geological disturbances. The Biotite Gneiss is the host rock with trending of North - South and dipping towards West. The dolerite dyke intruded between the country rock of Biotite Gneiss in a width of 85m which stretches about entire lease area with trending of N65oW – S65oE with vertical dipping. The black granite (dolerite) exhibits sub-ophitic texture, which is the special type of poikilitic texture. The Dolerite composed of laths of plagioclase embedded in the plates of Augite. Apatite, magnetite and Ilmenite form the secondary constituents.
STRUCTURAL SETTINGS OF THE AREA
AGE FORMATION Recent - Top soil ------Unconformity------Pegmatite and Quartz veins, Proterozoic to Late Archean Dolerites, Migmatites, Peninsular Gneissic Complex, Charnockite. It is a type of ferro – magneisan dyke rock comprised of mineral constituents such as pyroxene (Augite and Hypersthene) and plagioclase more plagioclase and augite provide Grey/Greenish Black Colour Upon polishing to this rock. The texture is a typical Porphyritic, with phenocrysts of plagioclase embedded over pyroxene matrix. The rock is fine to medium grained melanocratic and without any segregation or textural defects, but little boulders due to spheroidal weathering. This spheroidal weathering cause for more rejection. The color of the rock changes depending upon the texture of the rock. The Dykes is fine grained at the contact of country rock. Strike Direction - N65oW – S65oE Dip - Vertical dipping. 8
Scheme of Quarrying Iruthukottai Black Granite 3.1 DETAILS OF EXPLORATION 3.1.1. ALREADY CARRIED OUT As far as Black granite deposits are concerned, the only practical method is the systematic geological mapping and delineation of commercial black granite bodies within the field and careful evaluation of body luster, physical properties, engineering properties, commercial aspects etc. Such an exploration study has already been conducted in this area during the course of quarrying operations. This quarry was already attained a maximum depth of 19meters in the eastern side and the black granite is clearly visible from the existing quarry pit. Based on the valuable geological information and by the field experience the estimation of geological resources, mineable reserve is arrived at considering to waste and market potentiality.
3.1.2. PROPOSED STUDY TO BE CARRIED OUT Even though the depth persistence of the Black granite stone may be beyond 32m depth (2m topsoil + 30m Black granite) from the Petrogenetic character of the rock, only 32m depth persistent has been taken as economically viable depth to calculate categories of proved, probable, and possible reserves. The recovery of saleable Black granite stones has been taken as 30% and if the recovery percentage is good, it may enhance. No definite programs for future exploration have been drawn. If there is any considerable increase or decrease in the recovery factor a modified Scheme of Quarrying will be prepared and submitted to relevant authorities for subsequent clearance and approval.
3.2 METHOD OF ESTIMATION OF RESERVES The geological plan demarcating the commercially viable granite body has been prepared in 1:1000 scale (Plate No. IV). Totally five sections have been drawn, two along the strike direction as (X-Y and X1Y1) length wise and other sections are perpendicular to strike as (A-B, C-D and E-F) width wise which is suitably chosen to cover the maximum area, in the scale of Horizontal 1:1000 & Vert 1: 500 respectively (Plate No. IV). The cross sectional area for the proved depth persistence of 32m (2m topsoil + 30m Black granite) has been worked out for each section. The cross sectional area multiplied by its length of influence on the longer axis gives the volume (insitu) in the cross sectional area. The sum total of the insitu reserves available within the individual cross sectional area gives the Geological Resources of the lease area. The granite recovery percentage has been considered @ 30% during this scheme period. From the total Geological insitu resources, the quantity of saleable granite stones and quantity of granite rejects and waste generation are computed by applying recovery factor at 30% by its volume. As the salable black granite stone are in terms of cubic meters (Volume) only and not in terms of tonnage as in the case of major industrial mineral, the geological resources, mineable reserves and quantum of waste generated etc, are given only in terms of cubic meters. 9
Scheme of Quarrying Iruthukottai Black Granite The details of estimation of geological resources and mineable reserves with reference to the geological plan & cross section and Conceptual Plan & Section as shown in (Plate No.IV & IX).

Scheme of Quarrying Iruthukottai Black Granite The geological resources computed based on the geological cross sections up to the economically workable depth of 32m (2m topsoil + 30m Black Granite) below the general ground profile at the rate of 30% recovery yields 52,664m3 and 1,75,546m3 of ROM and Mineable reserves have been computed as 10,935m3 at the rate of 30% recovery with 36,457m3 of ROM (Refer Plate No. IV). The Black Granite body occurring in this area exhibits more or less uniform colour, texture and sold in Par with commercial granite deposit. If any variation occurs during quarrying, such as cracks flaws and patches, the defective area is removed during dressing and marketed. The mineable reserves are calculated by deducting the Mineral locked up area under safety distance and bench loss. Proved & possible reserves are categorized up to 32m depth from the elevated portion of the area.
4.0 CONCEPTUAL MINING PLAN: Conceptual mining plan is prepared with an object of long-term systematic development of benches, lay outs, selection of permanent ultimate pit limit, depth of quarrying and ultimate pit, selection of sites for construction of infrastructure etc. The ultimate pit size is designed based on certain practical parameters such as economical depth of quarrying, safety zones, permissible area etc., The ultimate pit dimensions of the quarry are given below. Table - 9
Dimensions in meters (Maximum) Pit Length Width Depth I 67 59 32 II 19 67 27
However, during extraction of blocks each bench will be of 5mts height & width, vertical slope for proper dimensional cutting. The total volume of excavation is estimated to be 39,908m3 (ROM 36,457m3 + Topsoil 289m3 + Side burden 3,165m3) to a depth of 32m. The generation of total waste is estimated about 28,687m3 and marketable Black granite is 10,935m3. During the present scheme period, excavated waste (13,930m3) will be proposed to dump on the northern side with dimension of 38m x 24m x 15.3m(H). Dumps are properly terraced systematically by multi-level dumping. When the quarry reach the ultimate pit limit or at the end of life of quarry, waste will be backfilled and commercial plantation will be carried out in the backfilled area and remaining pit will be allowed to collect the rainwater and seepage and the water storage will be kept as reservoir for charging the nearly wells and will be used for afforestation purpose. After completion of quarry operation quarried out land will be fenced with barbed wire also bund will be constructed around the quarry to prevent inadvertent entry of public and cattle. (Please refer plate No. IX). 12
Scheme of Quarrying Iruthukottai Black Granite 5.0 MINING No change in the method of mining. The same open cast semi mechanized mining with
5mt vertical bench with a bench width of 5 mtr has been followed.
Under the regulation 106 (2) (b) of the Metalliferous Mines Regulation 1961, in all open cast mining, the bench height should not exceed 5 mtr and bench width should not be less than bench height. The slope of the bench should not exceed 60˚from horizontal.
But as far as the quarrying of granite dimensional stones are concerned, observance of the provisions of Regulation 106(2) (b) as above is seldom possible due to various inherent petro genetic & mining difficulties. Hence, it is proposed to obtain relaxation to the provisions of the above regulation from the Director of Mines Safety, Chennai for which necessary provision is available with the Regulation 106 (2) (b).
The production of Black granite dimensional stone in this quarry involves the following method typical for granite stone mining in contrast to other major mineral mining.
Splitting of rock mass of considerable volume from the parent sheet rock is carefully removed by avoiding any kind of damage in the form of cracks adopting the method of diamond wire cutting along the horizontal as well as two vertical sides along the width direction and the third vertical face behind the front face.
This liberation of huge volume of granite body from the parent sheet rock is called primary cutting. The Blocks splitted above are toppled and removed from the pit to the dressing yard, by using hydraulic cranes.
Removing the defective portion and dressing into the dimensional blocks are done manually using feather, wedges, and chiseling respectively by the labours that are skilled in this work. The defect free, dimensional stone of different sizes is marketed in domestic and international market by the well experienced marketing personnel of the lessee.
The waste material generated during quarrying activity includes rock fragments of different sizes and waste chips during dressing of the blocks.
The total quantity of wastes is proposed to temporarily dump on the northern side.
When the quarry reach the ultimate pit limit or at the end of life of quarry, quarried out waste will be backfill. Excavated topsoil will be preserved all along the safety barrier and utilized for construction of bund, haul road and afforestation purpose (refer Plate No. VI and IX).

(Remaining reserves of 4,965m3 will be taken up for the remaining lease period of 10 years). The year wise quantum of work proposed and the details of estimation of production quantity and generation of waste are furnished with reference to Year wise Development and
Production plan (Plate No.V).
The proposed volume of production is 1,194m3 per annum and 5,970m3 during this scheme period at the rate of 30% recovery. More details of the year wise production parameter are explained with bench length, width and height in Plate No. V.
5.2 PROPOSED RATE OF PRODUCTION WHEN THE QUARRY IS FULLY DEVELOPED The proposed rate of production when the quarry is fully developed is 1,194m3 per annum @ 30% recovery. The production schedule for this scheme period is drawn mainly in consideration of reserves position, market demand, men, machinery development and the cost of production. 14
Scheme of Quarrying Iruthukottai Black Granite 5.3 MINEABLE RESERVES AND ANTICIPATED LIFE OF QUARRY: The dolerite dyke is deep seated in nature as they have been formed by basic intrusions from depth as dyke. The depth persistence of the dyke will be beyond the economically workable depth. The method of extraction of rock mass from dyke sheet rock is highly expensive at greater depth. An optimum depth of 32mts has been established as economically viable depth. Eventually this depth is optimum for safe and scientific quarrying. The Mineable Reserves are calculated by excluding the mining loss due to formation of benches with suitable height & width, ultimate depth of quarry, the Mineral Reserve held up within the safety distances all along the lease boundary. The Mineable Reserves for this Black granite quarry is thus arrived as 10,935m3 at the rate of 30% recovery and 36,457m3 for an assumed depth of 32meters from the elevated portion of the area. The details of estimation of year wise development and production plan (plate no. IV). The average rate of production of Black Granite from this quarry is 1,194m3 per year and 5,970m3 during this scheme period considering 30% recovery and remaining recoverable reserves of 4,965m3 will be taken up for the remaining lease periods of 10 years. Based on the above, and taking into consideration of the available Mineable reserves, the life of quarry will be about 15 years (considering all the safety factors) at 30% recovery, if the quarry is being worked continuously with an average annual production of 1,194m3. This calculation is based on the plan approved by Director of Mines Safety leaving Benches and Safety barriers. If the annual production increases considerably and consistently a modified scheme of quarrying will be prepared under Granite Conservation and Development Rules-1999 the same will be submitted to the relevant authorities for subsequent clearance and approval.

c). Miscellaneous: Apart from the above, the following tools and tackles are required for quarry operation.
A. For operation The operation of granite quarry requires the following loose tools material and have to be kept sufficiently in stock for non - interruption of the quarry work. 1. Drill roads - 0.3m ,0.4m , 0.5 m ,0.6m , 0.75m ,1.65m, 2.25m, 3m & 3.6m. 2. Steel Alloy chains of sufficient length of 12mm, 16mm, 18mm, and etc., sizes. 3.’D’ shackles to link the chain lengths. 4. Rubber hose of required length. 5. Hose clamps to link the compressor delivery hoses. 6. Feather and wedges of 6” and 12” dia sizes utilize for splitting the block from the mother rock. This is an important tool in the operation of a quarry. 7. Crow bars. 8. Spades. 9. Sludge Hammer 10. Iron Pans 11. Pitcher Hammer 12. Chisels. 13. Consumables, such as diesel, grease, Hydraulic oil, etc. 14. Stock of essential spare parts of machinery. 15. Explosive as per the licensed quantity ‘M’ type portable explosive Magazine with accessories. 16. Besides diamond wire saw equipment and new innovative machine specifically designed for granite with accessories are required to liberate the rock from the parent body rapidly to minimize damage and to obtain good recovery. Splitting the sheet rock by Diamond wire sawing which increases substantial recovery potential. Hence it is proposed to follow “Diamond wire saw cutting” for best recovery. The above machineries are adequate to meet out the simultaneous development and production schedule drawn out in this scheme. 16
Scheme of Quarrying Iruthukottai Black Granite 6.0 BLASTING a. Broad Blasting Parameters: In general for granite quarrying primary (deep hole drill) blasting is not practiced, only secondary blasting is practiced coupled with jackhammer drilling (30-35mm dia). These blasting are carried out for splitting the blocks from parent sheet mass. The granite industry needs blocks for about 3m x 2m x 2m for International buyers hence small blocks blasting pattern is not followed. The blasting pattern depends upon the texture of the rocks in the case of granite quarrying which in-turn depends upon the bedding plane, presence of fractures, fissures and cracks hence it is difficult to decide the definite particular pattern of holes in each blast. Nowadays Diamond wire saws are used for splitting the blocks from parent sheet mass. It is a new innovative Eco-friendly splitting technique without involving blasting. This is increase the recovery percentage of granite blocks and reduced from induce fissures due to blasting. Hence, it is difficult to pronounce a definite pattern of holes with regard to spacing, burden and depth. Hence, only blasting is deployed for secondary fragmentation for handling the wastes and not for production.
b. Type and use of explosives In granite quarries, only heaving effect is required and not the shattering effect. The aim is to recovery as large a block as possible. Hence only low intense explosives like D-Cord and Gelatin sticks are used. In granite quarrying it is very difficult to prescribe the charge/ hole as it depends upon the various factors like type of rock, texture, planes of weakness, required size of block, etc.
c) Storage of explosives: Authorized explosive dealers supply the explosive at site as per the day’s requirement. Hence question of storage of explosives does not arise at present. However, the lessee has been advised to install one portable magazine of ‘M’ type at the earliest possible opportunity. Splitting within the sheet rock is affected by diamond wire sawing which increases substantial recovery potential. Hence it is proposed to follow diamond wire saw cutting for better recovery of granite dimensional stone. During future development of quarrying, removal of over burden will be done by blasting with explosives in small dia holes drilled by Jackhammer. The explosive that will be used are D-Cord and Gelatin sticks that are indicated below. D Cord - 5mg Gelatin Sticks.
7.0 MINE DRAINAGE The water table in this area is 52m as observed in nearby bore wells. Working expected to well above the water table. If water is encountered at depth due to rainwater seepage, the same may be drained out by 5HP motor pumps and drained out water will be utilized for afforestation. 17

The total waste to be produced during this scheme period is about 13,930m3 the same is proposed to temporarily dump on the Northern side with dimension of 38m x 24m x 15.3m(H). Dumps are properly terraced systematically by multi-level dumping. When the dump becomes inactive excavated topsoil will be spread out over and sides of the waste dump also planting trees for increasing the stability of the waste dump and to prevent erosion during rainy season. When the quarry reach the ultimate pit limit or at the end of life of quarry, waste will be backfilled. The waste management plan with reference to the quantum of waste generated is shown in quarry layout and afforestation plan (Plate No. VI).

Scheme of Quarrying Iruthukottai Black Granite 14.4 PROPOSAL FOR RECLAMATION OF LAND AFFECTED BY MINING ACTIVITIES DURING & AT THE END OF QUARRYING In the proposed depth of quarrying is about 32m has been envisaged as workable depth for safe & economic quarrying. When the quarry reach the ultimate pit limit or at the end of life of quarry, waste will be backfilled and commercial plantation will be carried out in the backfilled area and remaining pit will be allowed to collect the rainwater and seepage and the water storage will be kept as reservoir for charging the nearly wells and will be used for afforestation purpose (Please refer plate No. IX).
14.5 PHASED PROGRAMME OF PLANTING TREES The safety distance along the eastern lease boundary will be utilized for subsequent Afforestation. Appropriate species of Neem, Mango, Pongamia Pinnata, Casuarina, Tamarind, etc., trees will be proposed to plant during this scheme period. Table -19 No. of Trees Area to be No. of trees Name Survival Year proposed to covered in expected to of the species rate % be planted m2 be grown 2015-16 20 160 80% 16 Neem, Mango, 2016-17 20 160 80% 16 Pongamia Pinnata, 2017-18 20 160 80% 16 Casuarina, 2018-19 20 160 80% 16 Tamarind, etc., 2019-20 20 160 80% 16
Careful measures will be taken to survive these plantations at 80% Survival rate nearly 800m2 area is proposed to be used under afforestation by planting 20 number of trees during every year and by growing 16 number of trees at a survival rate of 80%. The afforestation plan is shown in Plate No.VI.
14.6 MEASURES FOR DUST SUPPRESSION: As the granite stones are quarried as undamaged dimensional stones without involving deep hole drilling and heavy blasting, fragmentation and generation of lumps, fines or dust is very limited. This quantum of quarrying activity will not cause the dust detrimental to the health of the persons employed. Nevertheless, water will be sprinkled for the suppression air borne dust from quarry approach roads, waste dumps on regular intervals using water tankers. Drilling of blast holes of 32 mm dia will be always under wet conditions to prevent flying of dusts. In the unloading points, water will be sprinkled through tippers to suppress dust. The drillers are provided with respirators in accordance with the Mines Safety Regulations.
14.7 MEASURES TO MINIMIZE GROUND VIBRATION DUE TO BLASTING AND CHECK NOISE POLLUTION Shallow holes of 32 mm diameter will be drilled and conventional low explosives such as D-Cord, Gelatin sticks only will be used for removal of over burden and side burden. Hence, ground vibration and noise pollution will be minimal and restricted with the quarry workings. The blasting will be taken up at appointed timing and with sufficient caution to the public. The noise produced by diamond wire saw cutting will be negligible. 24
Scheme of Quarrying Iruthukottai Black Granite 14.8 STABILIZATION AND VEGETATION OF DUMPS As the waste generation in the quarry includes hard rock fragments of considerable size and irregular shape with varying angularity, the waste dump will be stable on its own even at higher slopes of the sides. However, excavated topsoil will be utilized for spread out over and sides of the waste dump also tree sapling will be carried out for increasing the stability and to prevent erosion during rainy season.
15.0 PROGRESSIVE QUARRY CLOSURE PLAN In the Black Granite quarry operation is proposed to a depth of 32meters for the entire life of quarry, this is based on the market potential at present scenario. Hence, the ground water will not disturb in any manner. Afforestation will be carried out and maintained in the boundary barriers till the plants reach the stabilize level. Office room toilet store room will be well maintained. The sludge from the toilet will be periodically removed and the same will be used as manure for afforestation. Sentries will be posted in the night to prevent the inadvertent entry of public. Sufficient caution and sign boards will be kept in and around the quarry to induct public for awareness. Blasting will be carried out in a specific time after giving sufficient caution to the public, sentries will be posted on a 1km radius with whistle and flags during small amount of blasting (blasting is carried out only for secondary fragments and not to liberate the Granite body from the parent rock mass). The waste generated during the quarrying operation is proposed to dump on the Northern side, which will act as temporary waste dump. Dumps are properly terraced systematically by multi-level dumping. When the working area reaches the ultimate pit limit or at the end of life of quarry, quarried out waste will be backfilled and commercial plantation will be carried out in the backfilled area. After completion of quarry operation quarried out land will be fenced with barbed wire also bund will be constructed around the quarry to prevent inadvertent entry of public and cattle. (Please refer plate No. IX). Garland drains will be constructed around the quarry to prevent the surface run-off of the rain water. Land use pattern Table-20

Scheme of Quarrying Iruthukottai Black Granite 16.0 MINERAL CONSERVATION AND DEVELOPMENT The Scheme of Quarrying proposed has fully covered the aspects of Granite Conservation and development rules 1999, with a future plan to extend the proposed working of the quarry to the maximum possible workable depth of the deposit. Extreme care is taken to ensure proper supervision of quality control of the Granite dimensional stone aimed at the recovery of the maximum saleable quality and quantity of granite dimensional stones suitable for full utilization of the consumers. Care is been taken for each process just to safeguard the material quarried in an economical and efficient manner by adopting systematic and scientific quarrying with the consultation and supervision of well experienced quarry persons.
17.0 STATUTORY PROVISIONS The provisions of the Mines Act, Rules and Regulations and orders made there under shall be complied with, so that the safety of the quarry, machinery and person will be ensured. Permission, relaxation or exemption wherever required for the safe and scientific quarrying of the deposit will be obtained from the Department of Mines Safety, Chennai. Any violation pointed out by the inspecting authorities shall be rectified as per the guidelines of the department.
Certified that this scheme of quarrying has been prepared in accordance with the Mines Act, Rules and Regulations and orders made there under and also in conformity with the provisions sub rule (13) of Rule 19A of Tamilnadu Minor Mineral Concession Rules, 1959 and Rule 12,13,16 of Granite Conservation and Development rules 1999.
