9 SCHEME OF MINING FOR SEMANGALAM BLACK GRANITE(DOLERITE DYKE) MINE (UNDER RULE 12 OF GCDR 1999) P A R T I 1.0 REVIEW OF MINING PLAN The Mining Scheme has been prepared in respect of Black Granite Quarry in S.F. No. 1/6, 2/1, 2/2A, 2/3B1 & 2/3B2 Extent Ha. of Semangalam Village, Vanur Taluk, ViluppuramDistrict, for which M/s. Karthik Raja Exports, R23A/A2, Ambattur Industrial Estate Road, Anna Nagar West, Chennai has a mining lease vide Government Order (3D).No.14 Industries (MMB-2) Department dated for Twenty years and the lease deed was executed on The period of lease is for 20 years upto The Mining Plan was approved by Commissioner of Geology and Mining, Guindy, Chennai vide letter No /MM5/2009 dated They have in the field of Granite Mining for the last Ten Years. They have adequate knowledge and skill on quarrying and export of dimensional granite blocks (Rough) to various Countries as well as to have a capacity to retain the domestic market. Black Granite is the commercial name for basic rock, petro logically known as Dolerite. This rock occurs mostly as dykes cutting across the country rocks. The Dolerite consists mostly of feldspar (Plagioclase), ferromagnesian minerals like pyroxene (Diopside Augite) with small quantities of Magnetite and Pyrite. The presence of magnetite mineral imparts steel black color to the rock. The rock exhibits ophitic texture with interlocking arrangement of mineral constituents. The ferromagnesian minerals impart the black colour, Hardness and compactness to the rock. The rock has a hardness of 6.5 to 7.5, Specific gravity 2.8 to 3.3, Wear factor-1, Unit weight 3.2. Tonnes/Cu.Mt. The black granite are commercially valued depending upon the physical characters such as color, grain size, texture, presence/absence of deleterious materials like Pyrite, Chlorite and Mica. The value increases when the material is fine grained and background of colour (i.e. intensity of black color). The length and width of the dyke depends on the major lineaments, faults, shear zones and pre-existing fractures. 1

10 About Granite Since time immemorial stones have been extensively used for building historic temples, places and monuments, World over races and countries have always accepted stones in all forms for daily use and for external use. For Indians stone is part of our culture, history and civilization. The numerous temples in India, particularly in South India have been built of granite blocks which have stood the test of time over several centuries. The over lasting freshness, beauty, elegance, toughness, hardness, durability and coexistence with ecology and nature have attracted man to stone. Stone is number one antipollutant natural product to with stand the modern industrial calamities like acidity and alkalinity. The World still wonders at the mammoth stone marvels of the wonders of the World. To-day the modern Stone Age has emerged in utilizing many types of stones in monumental, commercial and residential buildings. Granites are a term used commonly for igneous rocks which are widely used as building material. Although granite occurs widely throughout the World, there is considerable world trade in this commodity due to preference of buyers for a particular type of granite having special colour, dimensions, texture and above all its glossy finish, durability, aesthetic value and its stable property against vagaries of weather. There are more than 300 known varieties of stones in the World. From the Black Granites of Andhra Pradesh, Karnataka and Tamilnadu, India has emerged to-day with more than 60 varieties of different coloured stones. The a bony granite of Sweden, petit granite of Belgium, Impala Black of South Africa, Luna Pearl from Sardinia, Porrinho Pin of Spain, Balmoral Red of Finland, Grey and Pink varieties of China, Black and Pin varieties of India are well known in the market. To-day India markets only high quality granites in many colours except a few multi-colours which are moving in bulk quantities. The unknown stone from a remote village of our country adorns a modern building or adorns a cemetery in a metropolis in a highly developed country. 2

No. (3D).No.14 Industries (MMB-2) Department dated for Twenty years and the lease deed was executed on The lessee is submitting the First Scheme of Mining now Date of Commencement of Mining Operations The Mining Lease was executed on After the execution of Mining lease, the Mining operation was started immediately. The exploitation of Black Granite was taken up after removal of topsoil and some weathered gneissic rocks. The mining work was carried out in accordance with provision of the mining plan approved by Commissioner of Geology and Mining, Chennai. 3

12 1.4. (a). Deficiencies, if any, that existed in the approved mining plan to be taken note of and rectified by incorporating suitable proposals for implementation in the scheme of mining. There have been no deficiencies noticed in the quarrying area. 1.4.(b). Review of Compliance position of salient features of mining plan on chapter wise basis bringing out marked deviations, if any and justifications / reasons thereof. Item to be covered may include exploration, mine development, exploitation, afforestation programme, reclamation and rehabilitation, control of dust, noise and ground vibration and any other significant feature. (1) Exploration: During the mining plan period, the Geologist took the recovery percentage as 05% and the rock type was the natural one, except a thin weathered layer and soil cover, without disturbances on surface. However, during the mining operation of the quarry, the recovery percentage of Black Granite was very poor and this area requires more development work. We expected only 1.0m top soil and Weathered Granite but at the time of production it was observed that it was reached around 4-5m in most of the in the quarry. Below the topsoil, weathered gneissic rock has been noticed in the quarrying operation. After the removal weathered portion of gneissic rock, the saleable granitic part is reached. (2) Mine Development: Already two pits were existing near settle Southern boundary. But during mine plan period, of last 5 years, the development and production was taken from Southern side of lease boundary and the pit size is 28.0m (L)(Avg.) X 13.0m (W) (Avg.) X 16.0m (D) (Avg.). The present workings have reached a maximum depth of nearly 16.0m (average). Development of the pits has been done only in the areas where the Granite blocks could be easily mined. The Lessee considering the texture and color of this material, and in anticipation of the maintaining the percentage of recovery, the proposed mine development in the ensuing Five Years period of mining scheme is furnished in the year wise production and development plans as shown in Annexure-II and in Plate No V & V-A. (3) Exploitation (Production) m 3. Already the production of Black Granite from to was 4

13 The actual quantum of production achieved as against the proposals laid down in the Submission of mining plan letter dated , is tabulated as below: Sl. No Year pertaining to Production proposed in t Mining period In M 3 Actual production achieved In M TOTAL The production and development proposals for the ensuing Two Years period of scheme of mining is prepared in anticipation to the improvement of enquiries from the buyers for this Black Granite, is furnished in Annexure-II as shown in Plate No.V. (4) Afforestation As mentioned in the approved mining plan, 15 Neem trees per year were planted. The survival rate is less than 80% due to scarcity of rainfall. In the ensuing Five Years period 20 Neem trees per annum is proposed to be planted. (5) Mine Reclamation As proposed in the mining plan, the mine - pit will be utilized as a water reservoir after the mining activities are over. (6) Control of dust, noise and ground violations: The drilling and blasting parameters are in correlation with the proposals laid down in the approved mining plan. Shallow holes of 32mm dia. holes are drilled and the depth of hole will be generally about 1.0m. Water sprinkled for suppression of air borne dust on Mine haulage roads and waste dumps on regular intervals by water tankers. Drilling of blast holes will be always under wet condition to prevent flying of dust. In the unloading point of Tippers, water was sprinkled and further the drillers were provided with respirators in accordance with mines regulations. Conventional low explosives were used. Since the dimensional stones, which are needed to be without internal cracks, high explosives were not used. The scale of blasting was however very less considering the rate of production. Muffle blasting was not necessary as the area was free from dwelling houses, public utilities etc., Now wire saw machine is being utilized for primary cutting to liberate the required sizes of block from the parent rock The secondary splitting of the blocks been done by pressure-split method with the help of 5

14 feather and wedges. In view of above, there is no adverse effect on dust, noise and ground vibration by mining activities. (7) INFRASTRUCTURE: Infrastructures nearby the existing lease area. 1.

18 a. Estimation of Reserves: The Geological and Recoverable reserves are estimated by cross sectional method up to a depth of 32 mts, as the Black Granite. Plans and Sections have been drawn with a scale of 1:1000 and 1:500 respectively. b. Geological Reserves: The Geological reserve is estimated as M 3 by area cross sectional method. c. Recoverable Reserves: Top Soil: The Thickness of Top Soil noticed in this area is 2.0mts and the total volume of Top Soil will be 8720m 3. The mineable reserves and the recoverable reserves are 34975m 3 and 1750m 3 respectively, 10

19 3.3. Category-wise (Proved, Probable and Possible) Reserves Estimated in the earlier mining plan with grades. The geological reserves were calculated and estimated as 6090m 3. The Mineable reserve were calculated as 850m 3. Actually the Geological and Mineable reserves was calculated by applying recovery percentage of 05% and depth is taken up to only 16mts Depletion of Reserves: The geological reserves from at the time of presentation of mining plan were 6090m 3 and the mineable reserve was 850m 3. The depletion of reserves during the mining plan period was 375m 3, the production was achieved, and the production quantity is m 3.i.e. (from to ). For the ensuing mining scheme period, the recovery percentage is calculated as 05% based on the practical experience gained in this quarry. The granite occurring immediately after the top soil and weathered zone was full of cracks and joints. So only the recovery percentage of production was very poor in the first and second year of Mining plan period. After the development activities, it shows less cracks and it might expect good recovery percentage. 11

20 3.5. Additional reserves established category wise (with basis and parameters considered). There will be mentioned additional reserves in this period. Please refer Annexure I and Annexure III Category-wise updated reserves with grade (indicate and use grade with analysis) as well as marginal grades based on above. Sl. No. Details Reserve quantity in M 3 1. Geological reserve in the area was calculated 6090 during Mining Plan period 2. Mineable reserve in the area was calculated 850 during the Mining Plan period 3. Depletion of reserve during mining plan period Updated geological reserve is calculated in this 8689 scheme period 6. Updated mineable reserve is calculated in this scheme period CONCEPTUAL MINING PLAN 4.1. Time frame of completion of mineral exploration program in leasehold areas. Give broad description identifying potential areas to be covered in the given time frame. The mining operation has been started immediately after the execution of Mining lease. The production was achieved 05% of the estimated total mineable reserves in the mining plan period. Since the mine has been taken to the depth of 16.0m in the Southern side. The persistence of block granite is predicted upto 32.0m(2.0m top soil m Weathered granite m Black granite) depth and the configuration of the Black Granite deposit is fairly known. Hence no exploration is proposed Whether ultimate pit limit has been determined and demarcated on surface and geological plans. The ultimate pit limit of the mine has been determined and demarcated in the respective plan i.e., conceptual mining plan (Refer Plate No.IX). 12

As the waste generated during the mining practice is only the granite rejects and the non- recoverable/un-sized boulders, nibbles etc, their accommodation in the plain land is easier. The area for disposal of waste rock has been identified in the country rock area on the North and Eastern end, which is non-mineable area. There removal of over burden constitutes a top soil and a weathered layer, nibbles of different sizes, angularity etc. The unsold defective blocks are kept within the boundary on the country rock area. The waste dump has been denoted in the plate No: V, VI Whether back filling of pit(s) after recovery of ore / mineral upto technoeconomically feasible depth envisaged. If so, describe the broad features of the proposal. The depth persistence of the deposit may likely to be continued for little downward, it is proposed not to backfill the mine pit in this scheme period. Back filling will be proposed in the conceptual stage of mining Post mining land use envisaged. At the end of mining activities over, the mine pit may be utilized as a water reservoir (or) used for agriculture purpose MINING 5.1. Method of Mining Opencast method of semi mechanized mining will be adopted to extract Granite(Black Granite) of required size. Machineries like Tractor mounted compressor attached with Jack hammers is proposed to drilling and blasting. Excavators are proposed for quarrying of Granite and Tippers / Lorries are proposed for the transportation of Granite to the destination Mode of Working : 13

Depth of Water table: The ground water table is reported as 30m below ground level in nearby wells of this area. Now, the present quarry shall be proposed above the water table and hence, quarrying may not affect the ground water. 16

25 b. Arrangement and Places where the mine water is finally proposed to be discharged: The ground water may not rise immediately in this type of mining. However, the rain water percolation and collection of water from the seepage shall be less than 300 lpm and it shall be pumped about periodically by a stand by diesel powered Centrifugal pump motivated with 7.5 H.P. Motor. The quality of water is potable and it is not contaminated with any hazardous things HANDLING OF WASTE / SUB-GRADE MATERIAL As the waste generated during the mining practice is only the granite rejects and the nonrecoverable/un-sized boulders, nibbles etc, their accommodation in the plain land is easier. The area for disposal of waste rock has been identified in the country rock area on the North and Eastern end, which is non-mineable area. There removal of over burden constitutes a top soil and a weathered layer, nibbles of different sizes, angularity etc. The unsold defective blocks are kept within the boundary on the country rock area. The waste dump has been denoted in the plate No: V, VI Rate of yearly generation of wastes and proposals for disposal of waste for Next Five Years. (Indicate sequence of dumping with necessary plans and sections). The mine waste encountered was Overburden and mineral rejects are proposed to North and Eastern end, which is non-mineable area. The yearly rate of generation of waste as proposed during the mining scheme period as follows: Year Top Soil (in cum) Mineral rejects (in cum) Total Waste (in cum) TOTAL The above-mentioned proposed mineral rejects are proposed to dumping to the North and Eastern end, which is non-mineable area. 17

26 Build up of dumps from year to year to be shown in yearly plans and sections with description of the method & manner of disposal of waste rock, designed capacity & height of individual dumps and precautions envisaged for confinement of the dumps together with design details of the protective works. As the waste generated during the mining practice is only the granite rejects and the non- recoverable/un-sized boulders, nibbles etc, their accommodation in the plain land is easier. The area for disposal of waste rock has been identified in the country rock area on the dumping to the North and Eastern end, which is non-mineable area. There removal of over burden constitutes small amount of soil and thin weathered layer. The unsold defective blocks are kept within the boundary on the country rock area. The waste dump has been denoted in the plate No: V, VI, VII. The fine waste could be arranged that they be in confinement to the core portion whereas the boulders on periphery portion. The dumps will be maintained not exceeding 5m heights Rate of yearly generation of sub-grade mineral with reference to threshold values and proposals for stacking for next Five Years, (submit necessary plans / sections). (In case variations from the recommended threshold values of IBM, please give adequate justification and reasons). There is no recovery of sub-grade mineral. Though the Black Granite body exhibits a medium to wide range of differentiation in the color and texture, sub-gradation is not been done. However such materials, which were inspected and unapproved are stacked separately for future sale. Gradation into different quality is not necessary in this deposit due to the uniformity in the sense of rock type within the deposit Quantity and grade of sub-grade material available at the mine as on date duly supported by plans & sections and descriptive statement inclusive of the precautions adopted for storage. Not applicable. 7.0 USES OF MINERALS 7.1. Products and Application areas of Granites : Broadly there are six categories of granite products rough blocks, slabs, panels, tiles, monuments and others. Granites are most adoptable as interior veneers in sky scrapers. In architecture, granites are mostly used for artistic veneers as they enrich other aspects of buildings. 18

27 Slabs, Panels, Tiles and Monuments: Granite in the form of slabs of various sizes is mainly used in building monumental institutions, commercial and residential buildings. Slabs : A semi finished block of rectangular size with one side polished and the other outside sawn and thickness in the range of 20mm upto 20 cm. are used for interior wall panels in the building. Panels: Panels are used for covering the interior surface of the buildings, as tabletops and as interior wall paneling. Size of panel range from 50 cms x 100 cms upto 100 cms x 100 cms and thickness correspondingly varying from 20mm to 50mm. Tiles: Granite tiles are used as flooring material and also for wall cladding most preferred size is 30 x 30 sq. cms with 10mm thickness though sizes vary within the range 15 x 10 sq.cms and 60 x 60 sq. cms. Tolerance requirement in the international market on thickness is generally 0.1 cm to 0.2 cm. Monuments: Indian black granite is being exported in finished / semi-finished form for making monuments and tomb-stones for graveyards. Granite with good polish are mostly selected for making memorials ranging from simple markers and head stones to elaborate monuments and mausoleums. Some export of red granite monuments have also begun recently. Other Uses: In India granite is used as kitchen platform, kitchen sink, nameplates, foundation / inaugural stones etc., Granites ashtrays; flower vases and other art pieces which have both domestic and export markets. Other uses for dressed or cuter shaped forms of different sizes are as flagging stones in the form of flat slabs or rectangular or irregular shapes over steps, walk ways, parks and terraces, parking streets and highways or other traffic areas with rectangular blocks. Less known is the fact, that granites find important applications in the engineering fields as they possess high stability, non-denting and wear resistance qualities. These engineering grade granites are used in the construction of bridges, piers, sea and river walls, dams and related structures, bridges, super structures, grade separations and retaining walls. Granites are often used for the manufacture of inspection equipment, like surface plates, parallels, cubes, squares, straight edges, measuring prisms, guide ways of precision instruments and other metrological aids such as in weight measurements. 19

28 7.2. Changes proposed in the use of mineral, if any, with reasons No change is proposed in the use of minerals as the mineral is being sold out in raw form as per the buyer s requirement Changes in the specification, if any, imposed by the user industries and / or specifications required in the case of new user industries, if any, to be given. As mentioned above there is no specification imposed by the user industries. Because the buyers prefer the bigger size blocks called as Gang saw Efforts made for utilization of the sub-grade mineral including fines. As such there is no sub-grade mineral, there is no separate stacking of such wastes MINERAL BENEFICIATION 8.1. Results of any beneficiation investigations conducted and changes made in existing mineral beneficiation plant and tailing disposals, if any, with benefits expected (necessary) flow sheet and tailing dam designs etc. to be submitted as applicable). Not Applicable Beneficiation test done, if any, on sub-grade mineral including fines and proposals for installation of new or additional beneficiation facility, if any (furnish process details in brief along with expected tailings loss). The production of granite dimensional stones involving splitting of rock mass of considerable volume from the parent sheet rock carefully avoiding any kind of damage in the form of cracks, followed by Secondary Splitting into required size involves long hole drilling upto the bottom of the separated block and mild blasting along the required plans. The blocks splitter as above are toppled and removed from the pit, removing the defective portions and dressing into the dimensional blocks are done manually using feather and wedges and chiseling respectively the laborers who are skilled in this work, which is constantly supervised by experienced mining geologists. Nowadays modern techniques of wire- saw machines have been deployed for liberation of the rock from the parental rock, sometimes to the required sizes also. 20
