Vahanbhai Virabhai jograna which is located at Survey No: 61/1 paikee, Vill: Juna Jashapar, Tal: Sayla, Dist:Surendranagar, Gujarat. • Category of project – B • Sr. No. In the schedule – 1(a) • The existing Lease area – 0.96 hactare • The applicant Mr. Vahanbhai Virabhai Jograna is proprietor of this stone mining lease. • The Lease application. copy of Survey No: 61/1 paikee Pikee is attached as per Annexure – 1 of application. 1.2 BRIEF DESCRIPTION OF NATURE OF PROJECT . • Black Stone mining is a practice to extract Black Stone , mainly through blasting in Black Stone area in an open pit mining. Black Stone is a raw material for the kapchee, greet like construction material. In the construction buisness Black Stone plays an important role. • Black Stone is mineral present as stone benches. The height and thickness of bench is vary with place to place. The average thickness of the overburden is around 1.30 to 3.00 meters. The Over Burden or waste will be stacked separately temporarily for ultimate dispose off by means of backfilling and also for covering the mine area. Black Stone is excavated mechanically with blasting. The over burden/ waste is backfilled in worked out areas. The average annual production of Black Stone @ 1000 MT/Month. 1 1.3 NEED FOR THE PROJECT AND IMPORTANCE TO THE COUNTRY • The Mining project falls in the area of the Surendranagar district, Guajrat. As industrial growth and infrastructure growth is going on day by day in Gujarat, there is huge requirement of concrete or kapchee that plays a very crucial role in any developing countries. These Black Stone should be transfered to stone crushing plant for making different size of kapchee. 1.4 DEMAND AND SUPPLY GAP • As infrastructure growth is on peak in Gujarat, there is a huge demand of Black Stone as a raw material (To be used by stone crusher company). There is a marginal gap between demand and supply. 1.5 EXPORT POSSIBILITY • Black trap extract from the mining is transferred to the stone crushing unit. 1.6 DOMESTIC/EXPORT MARKET • Black Stone extract from the mining is transported to the nearby stone crushing unit. No export is proposed. 1.7 EMPLOYEMENT GENERATION (DIRECT & INDIRECT) DUE TO THE PROJECT. • About 5 staff members including labors directly and approximately 5 persons will be engaged indirectly in this proposed Black Stone mining project. Thus total 10 person will get employment including directly or indirectly. Considering 5 people in a family, total 10x 5 = 50 person will be benefited and shall depend on the mining activities of this mining lease area. 2 CHAPTER – 2 PROJECT DESCRIPTION 2.1 TYPE OF PROJECT (INCLUDING INTERLINKED AND INTERDEPENDENT PROJECTS, IF ANY) • This is an existing Mining project for production of mineral Black stone from the lease, having an area of 0.96 hectare. 2.2 LOCATION (MAP SHOWING GENERAL LOCATION, SPECIFIC LOCATION AND PROJECT BOUNDARY & PROJECT SITE LAYOUT) WITH COORDINATES. • The entire project area is 0.96 hectare. The area break up in the following table: Lease area Agricultural Grazing land Forest land Total (Ha) land (Ha) (Ha) (Ha) (Ha) 0.96 Nil Nil Nil 0.96 • The Project is located at Survey No: 61/1 paikee, Vill: Thoriyali, Tal: Sayla, Dist: Surendranagar, Gujarat. • Key plan of the project is attached as per Annexure –2 . • Layout plan and short view is attached as per Annexure – 3 & 4. 2.3 DETAILS OF ALTERNATE SITES CONSIDERED AND THE BASIS OF SELECTING THE PROPOSED SITE, PARTICULARLY THE ENVIRONMENTAL CONSIDERATION GONE INTO SHOULD BE HIGHLIGHTED. • Since it is an existing Black Stone mining and hence site specific, no alternative site considered. • The existing mining is in the lease area only for excavation of mineral Black Stone and overburden/soil layer. 2.4 SIZE AND MAGNITUDE OF OPERATION 3 • This is an existing Black Stone Stone quarry project in a lease area of 1.0 hectare which has capacity to produce Black Trap annualy @ 1000 MT/Month by opencast mining. 2.5 PROJECT DESCRIPTION WITH PROCESS DETAILS (A SCHEMATIC DIAGRAM/FLOW CHART SHOWING THE PROJECT LAYOUT, COMPONENTS OF THE PROJECT ETC. SHOULD BE GIVEN) • At present the manual opencast mining will be carried out. There is no overburden in the area. Mining in general will be carried out by manual open cast method by forming benches up to 2.0 to 3.0 m height. The sides of the benches have slopes at a safe angle not more than 45 degree from horizontal. Excavated Run Of Mine (ROM) will be subjected to manual sizing into fraction of +25 mm to – 100 mm. The yield of sized black trap will be around 85%, undersize limestone will be around 10% and remaining 5% as mining losses. Mining losses are on account of dust generation during drilling / blasting, wash off from the area etc. This sized black trap will be loaded into trucks manually and dispatched to the stone crushing plant. Remaining 10% of undersize material will be stacked on the worked out pit floor. Drilling and blasting will be also carried out by using air compressor and drill machine / jack hammer drill. Manufacturing process detail is attached as per Annexure – 5 of application. • Quarry limits of all workings are planned with a 7.5 mtrs statutory barriers against the lease boundary or roads existing in the lease hold. All haulage roads, the alignment of which keeps on changing depending upon the working in the pit, joins the existing surface roads of the lease hold. Four Wheeled Trolley attached to tractor will be generally used for movement of mineral. The mineral transported out of the lease hold will be with the help of tippers and trucks. • All pit working will be securely fenced as per the standards prescribed by DGMS. Approach roads to pit faces shall be maintained as required. • Mining will be carried out for black trap only. In the available thickness of 5 m of deposit, two benches are proposed to be developed. Width of bench is proposed to at 3 - 4 m. BLASTING 4 • The Black Stone being medium hard category requires some drilling and blasting for excavation. To maintain a bench height of 3 meters, drilling by 65 /100 mm dia drill machine, is recommended. However in future effort will be made to improve upon it. Blasting frequency is recommended as twice in every six days (i.e. twice a week). Benches shall be kept sloped at an angle of 15 ° from the vertical (i.e. 75° from the horizontal). Same angle of slope shall be maintained for drill /blast holes also. With 3 m high benches, sloped at an angle of 15° to vertical, the bench slope height shall be 3.1 m and with sub-grade drilling of 0.2 m. The depth of shot holes to be drilled shall be 3.3 m. BLASTING PATTERN • For every hole, one delay detonator would be used. Blasting would be done by using short delay action detonators to reduce ground vibration.
