10 9 CHAPTER 3 GEOLOGY & EXPLORATION 3.a. Topography Chikla Marble quarry lease area of hectare falls near village Chikla. The lease area consists of a part of hilly terrain. These rocks are spread all over the lease area. Lease area comprises rocks of Kumbhalgarh group of Dehli Super group. The hill ranges are extending is N S to NW SE direction dipping due west. The highest RL is 460 which lies in south western part of the lease area, where as the lowest RL is 419 falls within the South Eastern corner of the lease area. Rain water follow the natural slopes moves down from higher elevated area to low lying area. The lease area is a small & consist of hilly terrain only. No river or nalla exist in the lease area. The area is free from monuments such as structures of archeological or historic importance. There is no public road or Railway track either inside of in the close vicinity of the lease area that may effect due to mining operation. The lease area is almost devoid of soil cover. The nearest village is Chikla, which is 6km from Ambaji from the lease area. Ambaji is the nearest place, where all the facilities like education, medical; telephone, post office etc. are available. Electric line exists in the lease area. Company is having its own generator from which electricity is produced & used in the working. The climate of the area is semi-arid type. The average rainfall of the region is about 600 mm. The maximum temperature reaches in summer up to 40 0 C to 44 0 C where as minimum temperature goes down in winter to 2 0 C to 5 0 C. Maize, Wheat, Pulses are the major crops of the region. The lessee have developed the area completely & taking production from last so many years. However change in market condition, export policy & other factor has effected the production of mineral marble from the lease area. From this lease area mineral marble is produced & dispatched as marble rubbles.

11 10 3.b Geology of the area The geology of the area is shown over surface geological plan Plate No. IV on scale 1: 1000 & section over Plate No. V on scale 1: 100. In all five geological section has been prepared. 3.b.1 Regional Geology The stratigrapahic succession of the rocks of Banaskantha District may be summarized as under: STRATIGRAPAHIC SEQUENCE OF BANASKANTHA DISTRICT Post Delhi Intrusives Idar Granite (Malani igneous suite) Erinpura Granite and Gneiss Godhra Granite and Gneiss Sendra Ambaji Granite and Gneiss Porphyritie granite, granodiorite Granite gneiss/ granite Porphyritie granite, granodiorite Porphyritie granite and granodiorite Sirohi Group Rheodhar Formation Mica schist, marble, calcsilicate, quartzite/ migmatite Intrusive Phulad Ophiolite suite Pyroxenite, gabbro-anorthosite and granulite Kumbhalgarh Group Todgarh Formation Calc-gneiss, calc-schist, paraamphibolite/ quartzite. Gogunda Group Kelwara Formation Antalia Formation Feldspathic mica schist Quartzite, biotite-schist, marble Delhi Super group The Palaeoproterozoic Mesopraterozoic rocks are represented by the Delhi Super group which is exposed in the main Aravalli Hill ranges extending for over 900 km, from Delhi to Himmatnagar (Gujarat) with a NNE-SSW to NE-SW disposition. The part lying in Gujarat extends over 60km. Southwest of Himmatnagar these rocks are covered by alluvial blanket. The Delhis overlie the Aravalli Super group with a structural discordance and occur in the northeastern part of the State, mainly in the Sabarkantha and Banaskantha districts. The meta-sediments and meta-volcanic of the Delhi Super group, in Gujarat, are intruded by the variants of Erinpura and Sendra-Ambaji Granites, which have been

12 11 classified into Gogunda, Kumbhalgarh and Sirohi Groups in ascending order of superposition. Gogunda Group The metamorphosed, ferruginous and clastic sequence comprising interlarded quartzite and schist with subordinate impure calcareous rocks, deposited in the shelf zone of the Delhi geosyncline, has been included in the Gogunda Group is exposed in the Sabarkantha district and comprises two formations. The lower Antalia Formation consists of Quartzite, biotite schist, calc-silicate rock and calc-silicate marble, while the upper Kelwara Formation mainly consists of feldspathic mica schist. The group is tentatively correlated with the Alwar Group of north-eastern Rajasthan. Kumbhalgarh Group In Gujarat, the Kumbhalgarh Group is represented only by Todgarh Formation occurring in Banaskantha and Sabarkantha districts. This Formation extends from three km northwest of Kiriap (in Rajasthan) in the north to Khedbrahma (in Gujarat) in the south and comprises calc-silicate rocks, calc-gneiss, calc-schist, calc-biotite schist, impure dolomite, calcitic marble, para-ambhibolite and thin bands of quartzite. In Ambaji, the amphibolite, meta-rhyolite and meta-acid tuff occur in association with the schistose rocks and are the result of bimodal volcanism during Delhi rifting (Golani and Bhattacharya, 1988; and Reddy, et al., 1994). The meta-rhyolite and metaacid tuff are also found around zarivav and Amlimal. This felsic suite occurs within massive to schistose amphibolites, marble, biotite gneiss, and paragneiss. In zarivav Hill, dacitic-rhyolitic rocks show features, such as large and small pillows, pillow breccia, scoriaceous flow layers lapilli, quench fractures and gas escape pipes. 3. b.2 Local Geology:- Geologically the quarry lease area ( hect.) comprises of rocks of (post Aravalli age) Dehli Super Group only. In the area rocks of Dehli super group is represented by Todgarh formation of Kumbhalgarh group. This group comprises of calc-silicate rocks (Epidoite) dolomite, Marble & calc-biotite schist. In general marble of the area is fractured. Till so far no blockable marble is produced from the area. Below

13 12 the fracture & jointed zone, blockable (Marble) may be present. Frequency of fracture & joints decreases with increases in depth. Marble Weathered, fractured marble is exposed below at this layer of soil in the lease area. Marble of the area is white in colour with impurities & blach strips and hard, compact & massive in nature. The marble bed is dipping is western direction at an angle of 70 or so. Some of the marble of the area is one of the best quality marble available in the region & used as dimensional stone, statue, ornamental show piece manufacturing & other purpose. The rock is medium hard & suitable for slab cutting & good polishing. At present only rubbles of the marble are produced from the area. 3.c Exploration already carried out Deptt. of Geology & Mining Gujarat & Geological Survey of India have mapped the area on regional scale & located marble in the region. This lease area is under working from last 11 more than years. Lessee has developed one large size pit & exposed the marble bed. As mentioned earlier the marble bed is exposed over a complete lease area below a these layer of soil. The depth of pit varies from place to place, but the deepest level of exposure of marble be is of 415 RL of so. The pit has been developed by forming few benches both in marble. Marble Rubbles of different size from this area is produced. 3.d Exploration proposed to be carried out As lease area is small. Marble is available in depth also in the area. Looking to this sufficient reserves area available in the lease area hence no exploration is proposed in the area at this stage. 3.e Method of estimation of reserves As already mentioned, except the regional mapping no detail work has been carried out by any Govt. agency hence estimation of reserve is mainly based on the work of mineral marble of the area have been categorized as proved & probable category reserves depending upon the degree of certainty. Based on field visit, study of

14 13 lease area, work already carried out & other available information following parameters have been considered for estimation of reserves: For Proved Category Reserve (Category 111):- i. Economic axis: - The reserves in the area is economic the land of the lease area is Diversified forest land and available for mining. The detailed exploration has been carried out in the area. The cost of production is less than sale value therefore the reserves can be kept 1 of economic axis. ii. Feasibility axis: - The marble mineral of the area have ready market. The lease area has been fully explored. The land is available for mining therefore the reserves can be kept in 1 of feasibility axis. iii. Geology axis: - The lease area has been extensively mined. The area is fully explored. The exploration carried out in the area is sufficient and 10.00m.thick marble bed is available in the area. Therefore the reserves can be kept in 1 of geological axis. For Probable Category Reserve (category122):- Economic axis: - The marble in the area is economical because the land available for mining. The cost of production is less than sale value therefore the reserves can be kept maximum 1 of economic axis. Feasibility axis: - For the mining aspect since the deposit of the reserves need further exploration for determining. The exact quality and quantity of mineral. Therefore the feasibility on utility part (use) can be confirmed after only the proposed exploration. Therefore this reserve on feasibility axis is kept in UNFC Code 2. Geology axis: - Since the deposit of the reserves needs further exploration hence, therefore the reserves is kept UNFC Code 2 of geological axis. 1. Marble is available in complete lease area only. Hence complete lease area is considered for reserve estimation. 2. Reserves have been estimated by sectional area method. The area already excavated has been excluded from estimation of reserves.

15 14 3. Marble available upto 405 RL has been considered for prove reserves estimation. 4. Marble available between 405 RL & 399 RL has been taken for probable reserve estimation. 5. Sp. Gr. has been considered as A strike influence has been considered as depending upon section interval.(up to mid of nearby section / exposure. Based on work carried out so far following recovery factors has been considered for marble Blockable & Marble Rubbles. Blockable Marble - Nil of ROM Rubbles Marble - About 85 % of ROM 3.f Geological Reserves estimation Based on various parameters as discussed in above paragraph, geological reserves of marble in the lease area has been estimated. As the estimates are based on limited datas, the reserves may enhance in future when the more area will be developed in southern & western direction. The details of section wise reserves estimation is given at annexure. Details of sectional area: - Geological reserves has been estimated by adopting sectional area method for this based on excavation already carried out, geological features like rock type, marble exposure, dyke etc were mapped. Three sections across the marble zone covering complete lease area has been prepared. Based on various parameters as discuss in Para 3(e) reserves has been calculated for prove & probable category by adopting graphical area method. Which was subsequently multiplied area of influence of sp. gr. as per annexure VI. The summary of the reserves estimated for the area is as under: Reserve = Sectional area x St. Influence x Sp. Gr. (1) For Prove category reserves (Category 111) A A 1 = MT B B 1 = MT C C 1 = MT

16 15 Total = MT Say = MT (2) For Probable category reserves (Category 121) A A 1 = MT B B 1 = MT C C 1 = 91560MT Total = MT Say = MT Category wise reserves estimates as per UNFC code can be further summarized as under: Proved Reserves (111) = 28, 22,500 MT Probable Reserves (121) = 5, 08,500 MT Total = 33, 31,000 MT Based on various parameters, recovery factors, the reserves can be further bifurcated as under: S.

18 17 CHAPTER 4 MINING In Chikla Marble quarry of M/s Ambaji Minerals near village Chikla, Distt. Banaskantha small scale surface mining has been carried out by the lessee from time to time since 2002 or so. Marble present in this area as a thick zone running along the area complete lease area is mineralized. Marble is present on surface below a these soil cover. Although marble is present from surface, but it is highly fracture at top. The intercity of fractures & crakes reduces as depth increase. Overburden is topsoil removed by scraping the same soil will be stacked over statuary barrier and will be used for plantation purpose. Blockable marble may be present below fractured Zone. Till so far no bench of blockable marble has been developed. As thickness of overburden is less & marble is available in the area just below the topsoil of 1.00m to1.5m thickness, open cast mining method is followed. One large size pit has been developed in the area so far. The general dimension of pit is about 130m in length & width between 80 mt 120m. For systematic development, it is proposed that mining will be undertaken in almost complete lease area. Leaving statuary barrier. During year , Lessee has produce MT marble from the area. 4.a. Proposed Year wise development for the first year As mentioned above open cast mining method will be followed & mining will be carried out in the strike influence area of section. Hence it is proposed that major part of lease area should be developed properly & systematically during one year plan period. For this purpose proper benches will be developed. The maximum height of bench will be kept as 6m. Overburden / topsoil will be removed with the help of JCB/ excavator & dumper, which are mostly belonging to company & on hire basis. After removal of O.B., Marble will be produced with the help of drill machine, wire saw; crane etc. these rubbles will be further dressed & cut to give proper shape & size. The finished rubbles are loaded into trucks for onwards dispatches.

19 18 Proposed method of mining Proposed method is mechanized mining with the help of diamond wire cutting & cutting with chain saw. The working is proposed from surface to bottom in descending order. The maximum height of benches will be kept as 6m & the width of bench will also be kept as 6m (minimum). For the same i.e. in simple, the main phase of marble mining can be described as follows: (i) Removal of O.B/ Topsoil with the help of excavator. (ii) Cuts on Quarry front. (iii) Overturning the benches (iv) Sectioning, squaring & dressing of blocks into small transportable rubbles. These all phases (except one) of working will be done by wire saw cutting machining with the help of rock drill machine & compressor. The loading of marble rubbles & waste will be done by crane & excavators. Transportation of blocks rubbles & waste will be made by dumpers. The waste rock will be proposed to dump site on the location approved by the Govt. It is also proposed to undertake limited drilling & blasting in the area. It is also proposed to produce 2.00 Lac MT. It is also expected that marble blocks may be produced in depth (at deeper level) in future. The year wise excavation & production of mineral will be undertaken as per the plan & section shown over year wise development plan & section (Plate No VI). 4. a.1 First year ( ) It is proposed to increase annual production to the tune of MT. During first year of mining plan period. The development work will be carried out in both the section line i-e. along D-D & E-E. It is proposed that topsoil will be scraped in stacked over statuary barriers. Marble will be produced from two to three benches in all the section line. The orientation of bench will remain along N-S advancing east & west direction. The area proposed for working during first year is shown over year wise development plan & section.

Year wise plan and section of the proposed mine work are shown in plate No. VI. 4.d. Location of overburden, marble reject, marble stack and other details are shown in layout plan Plate No. VII. 4.e. Proposed Rate of Production when mining is fully developed and expected life of the mine Chikla marble mine is already developed & regular production of mineral marble rubbles are being taken from the deposit. However it is proposed to produce 2, 00,000

23 22 MT/year ROM (Rubbles) marble from the area during mining year plan period. This production target will be achieved by lessee by deploying more machineries. In all about MT of geological reserve of marble ROM of both proved & probable category Reserves have been estimated in the area. Considering 2, 00,000 MT ROM production in one year. The life of mine has been calculated as under: (a) Total geological reserve (Proved + Probable) = MT (b) Marble (ROM) production from area during Mining plan period = MT (c) Balance reserve (a b) = MT (d) Average yearly production after mining plan period = MT (e) Life of the mine after mining plan period = 12 Years (f) Total life of the mine = 17 Years 4.f. Conceptual Mining Plan: Exploration: - It is proposed to put one bore hole in the lease area of the deposit to prove depth extension & nature of marble present in the depth, so that future plan can be projected. However these bore hole will be drilled after mining plan period. Size & Shape of Pit: - It is proposed that by the end of lease renewal period i.e. upto the size of pit will be increased & become large pit, the depth of pit will be also increased. The pit will become more systematic in shape.by the end of lease period. The shape of pit will follow shape of lease plan. In general length of pit will be 300m & width will be 130m. Removal of O.B: - With the proposed production plan, it is expected that about m 3 additional overburden topsoil will be excavated after five years plan period. This overburden will be stacked all along statuary barrier. The length of soil stack will be about 5.00m. Plantation: - About 4000 Sq. m. area will be covered under plantation programme. Besides the local trees it is proposed to plant Mango, Neem, Kikar & other fruit plants in the area. This plantation will be carried out over lease boundary & out side lease area.

24 23 Few trees/ plants are present in the area. Out of these plants most of the trees/ plants belongs to native species naturally grown in the area. Post Land use pattern: - As mineral is available in depth & it is expected that same will be continued to be available in depth even after expiry of lease period. The area will be used for production of mineral (Rubbles marbles) Hence area will remain under use for mining purpose. Land use pattern at the end of lease period: - Excavated area Hect. Dumps - Nil Roads & Others Infrastructure - Nil Plantation - Nil Infrastructure - Nil Statutory barrier Hect. Unmined area - Nil Total Hect. 4.g. Proposed Method of Mining: - Looking towards the existing pit condition, position of benches, behavior of mineral deposit & production target from the area, open cast mining shall be continued with the removal of O.B/ topsoil by excavator & tippers, production of marble (Rubbles) mineral by use of wire saws & other allied machineries. As discuss earlier, systematic mining will be carried out by forming 6m x 6m benches & developing the pit in complete area. However the width of benches can be kept more than 6m if needed. The detail of the development of pit has been discussed in earlier paragraphs. In general three to five benches will be developed. OB will be excavated from top of benches by scraping & production of mineral will be taken from lower benches. 4.h Extent of Mechanization: - As mentioned earlier, this is a highly developed & mechanized mine and producing marble rubbles in good quantity i.e. approx 2.0 Lac M.T per annum. For the

25 24 proper development of the lease area, scrapping removal of overburden has been carried out by deploying excavators & dumpers. 1 Nos. of excavator & 3 Nos. of dumpers of different make & capacity is deployed at the side. For drilling work two air compressors & three drill machines are used. For the production of marble rubbles mobile crane, fixed crane chain saw, JCB Hyd. Power jack, Dressing machine etc. are used & available with the lessee. Electric supply is available near the area. Lessee is also having other machineries required for smooth running & working of the mine. Overburden/topsoil will transported to statuary barriers in dumpers. The blockable & rubbles marble will be transported to various factories located in nearby industrial areas viz. Abu Road, Ahmadabad & other distance area through hired trucks. Lessee is following the rule 21 (3) (C) of MDCR 2002 for deployment for machinery & equipment. Surface Transport Overburden will be transported to O.B. dump yard in Dumpers. The blockable marble if produced in due course of time will be transported to various factories located in Gujarat & other state by hired trucks. Rubbles will be dispatched to local small cutters (units) in hired trucks.

26 25 CHAPTER 5 BLASTING Marble of the area is hard & fractured, so limited blasting is carried out for fracture & development of cracks. Opening blasting will be carried with the help of cartridges of special gelatin of 80% strength or any available explosive with ordinary detonators & safety fuse. (a) Blasting Parameters:- Depth - 1.5m. Spacing & burden - vary depending upon existinu of cracks & fractures (b) Type of explosive:- Special gelatin 80% strength or suitable explosive will be used along with ordinary detonative & safety fuse. (c) Powder factors:- As control blasting will be carry out for development of cracks & joints only. Hence a powder factor is more. According to past experience. The powder factor at the mine is expected to be about 15MT/Kg. of explosive used. (d) Secondary blasting:- No secondary blasting will be required. (e) Storage of explosive:- The explosive will be stored in 50KG capacity for which license will be taken from Govt. Authorization. (f) Precautions required for fly of rocks and safety as required under MMR 1961 (i) All the approach roads will be guarded by the trend workers with the flags in their hands. (ii) Siren will be hooted before carrying out blasting operations.

27 26 (iii) The person, if, any within the blasting zone of 500m will be taken out of the blasting zone. All the other necessary precautions as required under MMR 1961 will be taken. (iv) Only 10 holes will be blasted at a time with the help of safety fuse as provided for in the MMR 1961.

28 27 CHAPTER 6 MINE DRAINAGE The lease area from the part of hilly terrain. The water table about 60m below the general ground level in the near by area. During the five year mining plan period, the proposed mining will reached upto 415 RL, which is about 25m above the general water level. The proposed mining will be restricted upto 415 RL only, hence ground water will not be intersected & the intake of water will be nil from mining pit. Rainy water may accumulate in the pit, which will be removed by pumping. As rains are not continuous, accumulated water can be dried also. The pump out water will be used for plantation purpose. The water will be taken from bore well; water will be used for sawing & sprinkling. There will very little wastage of water because in sawing process water will be used by recycle process.

29 28 CHAPTER 7 STACKING OF MINERAL REJECTS & DISPOSAL WASTE Disposal of waste 7.a Nature & yearly generation of waste:- As the area proposed for mining plan period is generally having these cover of hence very less topsoil will be generate. No overburden in the area is present, hence its generation will be nil. During the production of Rubbles 15% of ROM will be generated as a waste. The year wise generation of waste will depends upon, excavation production of marble. One retaining wall will be constructed at the OB dump yard as to avoid any side in dump yard/erosions. One waste dumps exist in the south western part of the area. This will also be removed & stacked in other area specify as dumping yard. The year wise generation of overburden & mineral reject/waste for coming five year mining plan period can be summarized as under: - Year Volume in m 3 Overburden Mineral Reject Total Waste Total ,49,832 1,71,542 Waste generated during one year of mining plan period will be stacked with in the area and on the land approved by competent authority as shown over lay out plan (plate VII). Stacking of OB will be done at statuary barrier & will be used for plantation. 7.b Selection of dumping site: - As mentioned earlier, part of the lease area is mineralized & area is very small, therefore it is not advisable to stack waste material with in lease area permanently. Therefore waste material will be stacked outside the lease area over lease boundary barrier. It is also proposed that lessee will approach to state Govt. for acquiring land

30 29 outside lease area for waste dump yard. The proposed location is shown in mine layout plan (Plate VII) can also be stack as marked by state government deptt. 7.c. Maximum height & spread of dumps: - About sq. mt. area will be required for stacking of waste material likely to be generated during coming five year of mining plan period. The height of overburden will be about 5m also. Stacking of overburden/waste material will be done in such way that proper benches can also be prepared, so as to make stack more stable, to avoid sudden collapse of overburden. About 85% ROM of Chikla area will be generated as a Rubbles i.e small size marble blocks. The sale of rubbles is not regular however small units purchases these rubbles for their production of small size marble tiles of 1 X 2 or even small than these sizes. Besides this rubbles will also be used for production of marble strips etc. The generation of waste material is about 15% of ROM production. The year wise generation of rubbles (sub-grade material) will be as under: - S. No. Year (a) (b) Quantity of sub-grade material Area required Height in M 3 MT for stacking M 2 MT (c) (d) (e) (f) Total ,49, The soil generated during the scheme period will be stacked initially in statuary barrier and will be utilized during plantation. 7.d. Generation of sub-grade materials: - Generation of sub grade material during mining plan period is Nil.

31 30 CHAPTER 8 USE OF MINERAL Use of Mineral: - Marble as the name indicate, this mineral is used as a building for manufacturing of stone slabs & tiles which are used for flooring and wall finish purposes, in building constructions. Marble is also used for manufacture of decorative articles like lamps, pillars, jhalis, fountains, temple, monuments, idols etc. The selling price of marble block depends upon its colour size of slabs, tendency to take polish. Selling price also depends upon size, mixing of other colours in torms of bands of any figures etc. selling price also vary according to presence of fractures, joints etc. The ultimate use of the marble depending upon the quality is given as under: Pattern Type of Marble Producture Traditional Marble Slabs & Tiles Flooring, Cladding of Columns, Building exterior, Staur case, Walls, Grave yard prefabricated units, Kitchen, Counters, Dividers, Sink, and Bath Tubs. Statutory White Soft Marble Making Statures and Monuments etc. Novelty Marble Block & Slabs Table Tops, Name plates, Vases and Candle, Holders. Other Marble Chips Industry and Construction rubbles for road & bridges, preparation of housing site, other construction works mixture paste and detergents. Use of Rubbles and Chips: - Rubbles are used for manufacturing small tiles. Rubbles are also used for industry construction. Rubbles are used for road and bridges, preparation of housing site other construction works. Chips are used for flooring and powder is used for detergents.

32 31 CHAPTER 9 OTHERS 9.a Site Services: In view of limited mechanized mining for production of Rubbles Marble smooth running of machineries all the infrastructure available at site it self. These infrastructures include office, rest house, first aid room, and store. Besides above all the basic facilities are provided at the site. 9.b Employment Potential: Lessee has employed all the statutory, technical & other persons are qualified so as to look after their work systematically. Lessee will appointed first class and second class mines manager and other technical staff. Besides the other administrative, marketing & financial persons, following staff will be employed at the side (including present strength of the staff): No. 1. Mining Engineer One 2. Mining Mate Two 3. Blaster One 4. Shawl Operators One 5. Dumper Operators Five 6. Compressor Operators Two 7. JCB Operators One 8. Mechanic One 9. Helpers Ten Besides above skilled, semi skilled & unskilled workers are also employed at the side. However their nos. may vary as per need & quantum of work. (Copy of PF slip of staff enclosed). At present 30 workers other thus above stall are employed at the side and it is proposed that about 40 workers (Including present strength) will be engaged at the side during mining plan period.

33 32 CHAPTER 10 MINERAL BENEFICATION Mineral Beneficiation: - The Marble is sold as a blocks or rubbles, no beneficiation is required. However it can be seen that blocks should be free from joint planes or fractures. As no beneficiation of mineral is being done, hence information as required under sub-head 10. a. to 10. f. are nil.

34 33 PART B CHAPTER 11 ENVIRONMENTAL MANAGEMENT PLAN 11.0 Base Line Information 11.a.(1) Land Use Pattern :- The lease area for which mining plan has been prepared is a part of hilly terrain. Hill comprises of fractured jointed marble & other rock the maximum height of the hill is 460 RL, which lies in south western part of area. The complete lease area is covered by a thin layer of top soil. The lease area was a part of forest land, but same has been diverted from forest land by central Govt. copy of diversion of forest land for marble mining is enclosed as annexure VI. Maize, wheat, pulses etc. are the common crops of the region. Mining operation has been already started in the lease area & depth of working varies with in pit itself. Existing land use pattern with breaking up. Nature of land Area in hect. 1. Pits & Quarry (Excavated area) Hect 2. Dumps Hect. 3. Road Nil 4. Plantation area Nil 5. Infrastructure Hect. 6. Statutory barrier Hect. 7. Area available for mining Hect. Total Hect. 11.a.(2) Water Regime : - There is no well, or reservoir exists within the lease area. As the area is part of hilly terrain, run off water is very fast. Rain water moves along the natural slope & ultimately goes to small nallah.

35 34 Ground water occurs at a shallow depth in a region. It is available at 80 m. below the general ground level in case of normal monsoon. 11.a (3) Flora & Fauna: - Except few bushes & trees planted by lessee no tree exist with in the lease area. Besides this the protected wild life also not present with in lease area. 11.a. (4) Quality of Water: - The quality of water is in the region is potable. 11.a. (5) Quality of Air: - Air in the area is clear with no visible impurities. Movement of automobiles is also less. Hence dust generation due to traffic movement is not detectable. 11. a. (6) Ambient Noise Level:- Like air environment, the ambient noise level is also seems to be below the recommended noise level standard of central pollution control board. No industry or other commercial activity other than mining is under way in the region. 11.a. (7) Climatic Condition: - The climate of the area is semi-arid type. The average rainfall of the region is about 600 mm. The maximum temperature reaches in summer up to 40 0 C to 44 0 C where as minimum temperature goes down in winter to 2 0 C to 5 0 C. Maize, Wheat, Pulses are the major crops of the region. 11.a (8) Human Settlements: - There is no human settlement within the lease area. Workers are coming from near by village. The occupations of the villagers are mainly farming, mining etc. The villages (With in 5 Km. radius) is as under: - S. No. Name of Village 1. Koteshwar 2. Chikla 3. Kumbhariya 4. Taleti 5. Ranpur

36 a (9) Public Building, Place of Worship & Monuments :- There is no public building, place of worship and historic monument with in lease area & 5 Km. radius of lease area except that public buildings in villages. Telephone or power lines are passing nearby lease area. 11. a (10) Does area fall under area under water (overburden & continue of pollution) Act, 1974: - Quarry area does not fall under such notified area. It is also proposed to dump overburden out side the lease area. This area will be acquire by the lessee with due approval of competent authority for the purpose hence area utilized under stacking & OB dump will remain almost same. 11. B. Environmental Impact Assessment: - The environment impact assessment will be made periodically for the land, air quality, noise level, vibration etc and if there will be any major changes that will inform to the proper authority. 11. B. (1) Land Environment: - The major part of area is already covered under working pit about sq. m. additional area will be covered under mining pit. The O.B. stack will be continue to be stacked within & out side the lease area. The area will be used as a matured mining site. The depth of pit will be increased in part of the lease area only. Land use pattern at the end of plan period will be as follow: - Nature of land Area in hect. Excavated area Hect. Dumps - Nil Roads & Others Infrastructure - Nil Plantation - Nil Infrastructure - Nil Statutory barrier Hect. Unmined area - Nil Total Hect.

37 36 The area covered under statutory barrier zone is hect. The area is already covered under sub-head dumps, plantation, infrastructure, road & unmined area. Part of overburden & waste will be dump out side the lease area, so that area can be kept as such for future development & to avoid rehandling of waste. 11. b (2) Air Quality :- From Marble mining there would be no significant influence on the ambient air Quality, because in mining operation no such machinery will be used which can generate considerable amount of dust in the surrounding environment. Drilling will also be carried out to a very limited extent, so that it may not pollute air environment. 11. b. (3) Water Quality:- The mining activity during plan period will be restricted to 370 mrl neither water table will be intersected by the mining activity nor the natural water flow and drainage on the surface will be affected. The site of dumping waste rock were also be so chosen that the dump will not disturb or intervene the flow of surface water nor the dump should flow in the agriculture land. All these combine have no effect on water quality of the area. The drainage system will not be disturbed due to mining activity. To avoid filling of water in working face a channel around the pit will be put in such way that all the water will move through there channels & ultimately goes to main natural stream. 11. b (4) Noise Level :- The noise level generated due to drilling by running of compressor & other machineries would not be any significant as the mine area is far away from local residential areas. Besides this playing of trucks, trippers etc will also not have any significant impact on noise level. During working hours also noise level will be below the permissible limit. 11. b (5) Vibration Level :- No vibration effect is likely to occur because blasting work will not be undertaken in the area.
