The project name is Mr. Virabhai Devabhai Rabari which is located at Survey No: 194 Paikee, Vill: Thoriyali, Tal: Sayla, Dist: Surendranagar, Gujarat. Category of Project – B Sr. No. in the schedule – 1(a) The existing Lease area- 1.86.16 hactare The applicant Mr. Virabhai Devabhai Rabari is proprietor of this stone mining lease. The Lease application copy of survey no 194 paikee is attached as per Annexure – 1 of Form – 1 application. 1.2 BRIEF DESCRIPTION OF NATURE OF PROJECT Black Trap Mining is a practice to extract Black Trap, mainly through lasting in Black Trap area is an open pit mining. Black Trap is a raw material for the Kapchee, greet like construction material. In the construction business Black Trap plays an important role. Black Trap 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 Trap is excavated mechanically with blasting. The over burden/waste is backfilled is worked out areas. The average annual production of Black Trap @ 42000 MT/Year/ 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 Guajrat, there is huge requirement of concrete or kapchee that plays a very crucial role in any developing countries. These Black Trap should be transferred to stone crushing plant for making different size of kapchee. 1.4 DEMAND AND SUPPLY GAP As infrastructure growth as on peak in Gujarat, there is a huge demand of Black Trap as a raw material (To use by stone crusher company). There is a marginal gap between demands any supply. 4 | P a g e 1.5 EXPORT POSSIBILITY Black Trap extract from the mining is transferred to the stone crushing unit. 1.6 DOMESTIC/EXPORT MARKET Black Trap extract from the mining is transported to the nearby stone crushing unit. No export is proposed. 1.7 EMPLOYMENT GENERATION (DIRECT & INDIRECT) DUE TO THE PROJECT About 15 staff members including labors directly and approximately 20 persons will be engaged indirectly in this proposed Black Trap mining project. Thus total 18 people will get employment including directly or indirectly. Considering 5 people in a family total 35x5 = 175 will be benefited and shall depend on the mining activities of this mining lease area. 5 | P a g e CHAPTER – 2 PROJECT DESCRIPTION 2.1 TYPE OF PROJECT (INCLUDIUNG INTERLINKED AND INTERDEPENDENT PROJECTS, IF ANY) This is a proposed Mining project for production of mineral Black Trap from the lease, having an area of hectare. 2.2 LOCATION (MAP SHOWING GENERAL LOCATION, SPECIFIC LOCATION AND PROJECT BOUNDARY & PROJECT SITE LAYOUT) WITH COORDINATES. The entire project is 1.86.16 hectare. The area breaks up in the following table: Lease area (Ha) Agricultural Land (Ha) Grazing Land Forest land Total (Ha) (Ha) (Ha) 1.86.16 Nil Nil Nil 1.86.16 The Project is located at Survey no: 194 paikee, Vill: Thoriyali, Tal: Sayla, Dist: Surendranagar, Guajarat. Key plan of the project is attached as per Annexure – 2 of Form – 1. Layout plan and short view is attached as per Annexure- 3 & 4 of Form-1. 2.3 DETAILS OF ALTERNATE SITES CONSIDERED AND THE BASIS OF SELECTING THE PROPOSED SITE, PARTICULARLY THE ENVIOURNMENTAL CONSIDRATION GONE INTO SHOULD BE HIGHLIGHTED. Since it is an existing Black Trap mining hence site specific, no alternative site considered. The proposed mining is in the lease area only for excavation of mineral Black Trap and overburden/soil layer. 2.4 SIZE AND MAGNITUDE OF OPERATION This is an existing Black Trap quarry project in a lease area of 1.86.16 hectare which has capacity to produce Black Trap annually @ 42000 MT/ear by opencast mining. 6 | P a g e 2.5 PROJECT DESCRIPTION WITH PROCESS DETAILS (A SCHEMETIC DIAGRAM/FLOW CHART SHOWING THE PROJECT LAYOUT, COMPONENTS OF PROJECT ETC. SHOULD BE GIVEN) At present the manual opencast mining will be carried out. There is no overburden is the area. Mining in general will be carried out by manual open case 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 Black Trap 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 details is attached as per Annexure – 5 of Form – 1 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 developed width of bench is proposed to at 3 – 4 m. 7 | P a g e BLASTING The Black Trap being medium hard category requires some drilling and blasting for excavation. To maintain a beach 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 sis days (i.e. twice in every week). Benches shall be kept sloped at an angle of 15˚ to vertical, the bench slope height shall be 3.1 m and with sub – grade drilling 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.
