7 DETAILS OF THE MINE Mine Area: This mine lease (ML) area is located at Gummalapadu Village, Pamuru Mandal, Prakasam district, A.P. The mine site extends over an area of 7.0 Ha. The Quarry lease area is located at a distance of about 2.86 Km from Bhoomireddypalli Village. Stages/Cycle Time of quarry development: a) The southern and northern part of the present pits gives the better granite blocks. The workings are commenced from center of the Q.L. area and it will be extended towards north and south. b) The waste consisting of smaller size and defected boulders is extracted from the surface and converting larger size boulders into granite blocks by conventional methods and the machinery like an excavator and two tippers, two compressors and six jackhammers are deployed to obtain target production. c) Extraction of Granite blocks by modern methods like developing benches of working face. d) Dressing of marketable blocks. e) Extraction of large Boulders: by removal of small and defect boulders from working face, the large size boulders are selected to split into dimensional blocks. Usually the natural joints present in boulders are taken as advantage for splitting and separation of the dimensional blocks from mother rock. A line of Drill holes are drilled in large size boulders and it is split with offset cutting. For drilling purpose, six jackhammers and two Compressors are used. Extraction of Sheet Rock: a) No sheet rock is exposed in this area at present. Small boulders are available at higher altitudes and large boulders are exposed at lower levels of the lease area. So, the production is obtained only from the boulders. Scheme of Development and Production for next 4 years in 5 years ( to ): The scheme of development and production for next first four years has been planned taking into consideration the nature of the deposit within the lease area. It is observed that the northern and southern part from the existing pits of the lease area is covered by larger boulders between 223m RL to 210m RL. So, it is proposed to advance the present working pits towards north and south in next four years.

8 YEAR WISE DEVELOPMENT: As a first step towards regular production schedule the boulder will be scooped out form top bench of 3m height in every year of the proposed mining area. In this process the under size boulders, which will not give the cutter size blocks (0.6x0.6x0.5m) and defected boulders will be treated as waste and this waste will be separated from workings face and shifted to proposed dump yard. In every year about m 3 to m 3 of waste will generate from proposed mining. During next four years of this plan period, about 6480 m 3 of waste will generate in total as details are given. Year Proposals of AMP Production (M 3 ) Granite Waste (M 3 ) 1 st nd rd th Total Year : In this year, the northern faces of the existing pit-2 will be advanced towards north over a length of 80m, width of 15m (each bench) in four benches of 3m height each between the R.L. of m and obtained about 1440m 3 of Granite blocks and 12960m 3 of mineral waste. Year : During second year, the workings will be advanced towards north from first year workings in four benches over a length of 80m, width of 15m between the RLs of m and obtained about 1440 m 3 of Granite blocks and m 3 of mineral waste. Year : During third year, the first year workings will be advanced towards south in four benches over a length of 80m, width of 15m between the RLs of m and obtained about 1440 m 3 of Granite blocks and m 3 of mineral waste. Year : During the fourth, the third year workings will be advanced towards south in four benches over a length of 80m, width of 15m between the RLs of m and obtained about 1440 m 3 of Granite blocks and m 3 of mineral waste.

9 Separation of Primary blocks from in-situ Rock by pre-splitting (primary cut) Line Drilling Method: 1. Once the small boulders are removed from the surface of the hill, the primary cut is taken up in large size boulders in close spaced jackhammer drill holes to dislodge large blocks from the in-situ boulders. 2. Presently the applicant is using line drilling method only and this method involve drilling of series of holes with jack hammer at 15cm interval in a straight line. 3. The jackhammer holes are for wedge cutting and the granite blocks will be separated from the large boulders. 4. The use of explosives causes for fragmentation and for development the cracks in rock. So the usage of explosives will be avoided in boulders formation. If any sheet is exposed below the boulders, the low strength explosives like gun powder will be used. 5. Thus the block will separate from the mother rock, which is pulled off from the face with cranes or excavator. Sub Division of Large (Primary) Block into Secondary Block (Secondary cuts): i. Once the primary blocks are dislodged from large boulders, these blocks are carefully observes fro defects like cuts, fractures, black line s& patches and the un-defected primary blocks by offset cutting. ii. The commercial blocks shall be trimmed so as to form right angles to each other. Flows like black lines, fractures and penetrative cracks are taken care of this stage for forming commercially marketable blocks. iii. The size of the blocks that could be formed form primary block to secondary blocks could not be much difference because these blocks are derived from the boulders of the granites as given below. Length : 120 to 60cm Width : 80 to 50cm Height : 60 to 50cm

Drillers Compressor Operator Cutters Helpers 12 TOTAL 48 Nos. LIFE OF THE QUARRY: Based on the present market demand, it is proposed to raise about 1440 m 3 of granite per year on an average. At this rate of production the expected life of the quarry for the present mineable reserves= 27,223/1440 = 18.9 or 19 Years. The reserves will be revived

11 after next five years based on the data collected for proposed mine workings. Accordingly the life of the mine will be changed. DRILLING: Drilling plays vital role in determining the size and shape of rough blocks. Drilling pattern is important in developing a working face and also is preparing the rough blocks suitable for their use in appropriate processing units. BROAD DRILLING PARAMETERS: A. Drill-Hole pattern: For primary and secondary cuts, Uniform single line equidistant holes (line drilling) will be drilled for separation of blocks from boulders depending up on the boulders size. The same technique is employed in the sheet rock zone also. In the case of large boulders, the primary drilling will be in the form of equidistant vertical holes to take out blocks. B. Drilling Parameters: i. Drill holes diameter: 74/Pmm ii. iii. Depth and inclination of the blast holes: 3 meter in case of separation primary blocks depending on the boulders/block size. Then the drill-hole will be vertical. Spacing and burden : 15cmx1.5m to 1cm. C. Handling of blocks within the Quarry: The applicant will deploy and excavator with a Bucket Capacity: 1 m 3, Boom length: 7m, Model:beml 2000 and 10 tonnes capacity crane at his mine to handle primary and secondary blocks. D. Transportation of the blocks from quarry to yard and to the destination: The applicant will deploy two tippers at mine site to transport the waste, unfinished and finished blocks from quarry site to stock yard and hired trucks will be used to transport sized dimensional blocks from stock yard to destination. The loading of blocks will be done by excavator or crane. HANDLING OF WASTE/SUB GRADE MATERIAL: Solid Waste: About 90% of the granite production is going to be generated as solid (granite) waste. At this rate about m 3 of solid waste consisting of under size boulders and defected granite will

12 generate during four years. Adequate non-mineralized area is available on western side for waste dumping. During life of the mine about m 3 of waste will generated. In view of that has been stated above about 51840m3 of Granite waste will generate during four years. It is planned to dump the waste in Q.L.area on western side in soil cover. Since the proposed dumping area is located close to the workings, it will be possible to utilize the waste material for back filling at the end of mining. USE OF THE MINERAL: The lessee is doing the Quarry for Colour granite for last five years and he is supplying granite sables to the domestic and to international market after cutting and polishing in their polishing unit, located in Prakasam District. MINERAL BENIFICIATION: The rough granite blocks will be cut and polished in lessee s industry as slabs and the same will be supplied to the domestic and international market. ENVIRONMENTAL MANAGEMENT PLAN The Environmental Management Plan envisage for this Mining Project is described here under with a strong commitment to follow the best Environmental Practices to reduce the negative implication to make this Project a sustainable development endeavor. The management action plan aims at controlling pollution at the source level to the possible extent with the available and affordable technology followed by treatment measures before they are discharge. Air Environment and control measures: The proposed mining activity would result in the increase of suspended particulate matter due to fugitive dust resulting from mining operations and transportation activities. Wet drilling will be adopted to suppress the dust generated during drilling. This water will also aid in cooling the drill bits it will be re-circulated.

13 Dust emissions and particulate emissions mitigation measures will be through water spraying at all the sources of dust formation and these measures are further elaborated as follows: Dust rising due to drilling will be controlled by covering the drill rods with cloth; dust extractors will also be employed. Regular water sprinkling at dust emanating sources viz., drilling, storage dumps and transportation through haulage roads, etc will be carried out. Regular grading of haul roads and service roads will be taken up to clear accumulation of loose material. Periodic maintenance of transport vehicles and equipment will be carried out to check emission levels. Greenbelt will be developed with avenue plantation all along the haulage roads and peripheral plantation all around the mine in order to control dust. Overloading of trucks will be avoided and carrying the ore/mineral in covered trucks will be taken-up to minimize pollution levels. Water will be sprayed on haul roads for minimization of resuspension of dust due to transportation. Water Pollution Management: No rivers and other perennial water courses flow through the ML area. However, during rains the water flows through the slopes of the ML area and across the mine lease boundary and joins a natural drainage. The rainwater that collects in the mine pit bottom during the rainy season will be utilized for water spraying on the haul roads and mining area. This water will also be used for the plantation in and around the Mine Lease area. The total water requirement will be 7.0 KLD which will be utilized from nearby bore well and treated water from septic tank. The usage will be as follows: Spraying/Sprinkling on dumps, haulage roads KLD. Plantation KLD. Domestic Use KLD.

14 The following that flows in the core zone will be routed adequately through channels to avoid any erosion and contamination. The mine pit water collected due to rains will be utilized for water spraying on the haul roads and for watering plantation. The waste water generated from the domestic usage will be fed to septic tank followed by soak pit. Noise Environment: There will be intermittent noise levels during drilling and while usage of jack hammer. The noise levels are expected to be below 75dB. This will however be for very short duration. No mining activities are planned during night time. A thick green belt will be developed to act as noise attenuator. The management plan for controlling noise pollution is envisaged as follows. The noise generated is very much minimum as the Colour Granite quarries is majority of manual and minimum Vehicular Traffic. The machinery will be maintained properly to reduce the noise levels. The protective noise reducing gear like earmuffs, the company will provide earplugs. Proper maintenance of equipment. Machinery will be fitted with properly designed noise generating acoustic silencers. Providing noise insulation/padding wherever practicable. Proper maintenance and periodic lubrication of noise generating parts of the machines Provision of thick plantation in and around the mine is planned in order to reduce the noise and prevent it from reaching to surrounding habitation areas. SOLID WASTE At this rate about m 3 of solid waste consisting of under size boulders and defected granite will generate during four years. Adequate non-mineralized area is available on western side for waste dumping. During life of the mine about m 3 of waste will generated. In view of that has been stated above about 51840m3 of Granite waste will generate during four years. It is planned to dump the waste in Q.L.area on western side in soil cover.

15 GREEN BELT DEVELOPMENT The development of greenbelt in the peripheral buffer zone of the mine lease area will be undertaken well before the starting of the mining activity. Green Belt has been recommended as one of the major component of Environmental Management Plan, which will improve ecology, environment and quality of the surrounding area. Plantation will be done along the haulage roads and the unused area in the ML area will be developed with green cover. Suitable advice on this plantation activity will be consulted with the local Forest Department along with measures to ensure good survival rate. Concepts of Green Belt Development The concepts of Green Belt Plantation scheme are 1. Nature of Pollutants 2. Emission Levels 3. Maximum Impact zone CRITERIA FOR SELECTION OF SPECIES Species to be selected should fulfill the following specific requirements of the area - Availability of seed material - Tolerance to specific conditions or alternatively wide adapts ability to ecophysiological conditions. - Rapid growth - Capacity to endure water stress and climatic extremes after initial establishment - Differences in height, growth habits - Pleasing appearance - Providing shade - Ability of fixing atmospheric Nitrogen - Improving waste lands. DESIGN OF GREEN DEVELOPMENT The greenbelt shall be developed around the plant to act as a sink for pollutants, attenuation of noise levels and improvement in aesthetic quality of the plant. The following criteria shall be adopted in the design of greenbelt:

16 1. Generally fast growing trees should be planted as otherwise it will take many years for other types of trees to attain their full height. 2. Trees will be planted along the road side in such a way that there is no direct line of sight when viewed from appoint outside the foliage perimeter. 3. Trees growing up to 10 m or more in height with thick perennial foliage should be planted around the plant. 4. Sensitive species such as magnifier indica should be planted in patches along the entire greenbelt to work as an indicator of pollution. 5. Trees shall be planted staggeredly in each row (minimum three rows encircling the perimeter of the plant). 6. Tree trunk being free foliage up to a height of 2 to 3 m, it is advisable to grow shrubs in front of trees to give coverage to the open portion. 7. Greenbelt will be developed all around the plant area with a width of 10 m. 8. Greenbelt will be developed around the plant except wherever buildings and other structures. 9. Local Plant species will used for development of green belt. SOCIO-ECONOMIC ENVIRONMENT This mining project will contribute in the development of economic status of the region and indirectly provide a platform for many businesses; both on small and big scale. These include direct employment and indirect employment in transportation, vehicle/equipment maintenance etc the company management would give preference to local people through both direct and indirect employment. There will be generation of indirect employment due to the proposed activity like transportation etc. SAFETY AND ENVIRONMENT Complete evacuation of the mining area at the time of drilling & blasting will be followed strictly. The proponent will provide all necessary provisions stipulated under the Factories Act and mines act. In addition a safety committee will be formed and manned by equal participants from Management and Workers. The management firmly believes in the concept of safety and environmentally sustainable growth. The authorities and staff are very much concern in Environment issues.

17 The management is going to develop scientifically designed green belt around the premises to mitigate air and noise pollution impacts on the surroundings. The management proposed to monitor ambient air as per APPCB guidelines. All the employees are provided with personal protective equipment such as helmets, hand gloves, safety shoes, goggles and apron as per their place of work. The management will provide safety training to all employees periodically and regularly. POST PROJECT ENVIRONMENTAL MONITORING PROGRAMME In order to maintain the environmental quality within the standards, regular monitoring of various environmental components is necessary. The mines manager will take care of Environmental Management activities with objectives as To implement control/mitigation measures To monitor this implementation process To determine and improve the efficiency of the implemented measures To identify any other unforeseen effect on environment not covered hereby and To inspect and maintain the plantation survival rate, regular cleaning drains, channels and water logged ponds and improve the drainage system and retaining walls over certain timelines. Regular training will be given to mine workers as per DGMS rules. Regular monitoring of various environmental parameters shall be carried out through third party to ascertain the following points: Status of air, noise, water, land pollution within the plant and in its vicinity; Generate data for predictive or corrective purpose in respect of pollution; and To assess and monitor environmental impacts periodically. The frequency of monitoring will be done as per norms. PROJECT SCHEDULE AND COST ESTIMATES: The envisaged avg. annual production of Colour Granite in a year is estimated to be 1440 M 3. The cost of the project: 40.0 Lakhs

18 The cost estimated for Environmental Monitoring is Rs. 4.0 Lakhs CONCLUSIONS The land that is going to be disturbed cannot be reclaimed during the lease period, as the Colour Granite is persisting at further depth and it will take a very long time to exhaust. No measures are proposed for reclamation of the disturbed land during the next five years. There is no other significant negative impacts are anticipated as the involved mining activities are very small. All possible measures shall be adopted to control pollution emissions to the minimum and kept below CPCB/MoEF/SPCB standard norms (Air, water, noise standard limits).
