3.2 Local Geology

The country rock in the lease area is massive Charnockite. Due to massive nature, planar features like mineral foliation are not discernable. Joint planes are the only planar features o . t o o o t t N55 E- 55 25 N is observed. The top soil profile in the area is very thin of about 0.5m or below. The top soil along with the overburden comprises thickness of about 1.0 m, and rarely exceeds above 1m only in a few pockets

The geological parameters / features of the ore body as obtained from the field mapping and exploration studies reveal the following.

Joint strike : N55⁰E-S 55⁰W Dip : 25⁰ N Length of the ore body : ranging from 160-210 m. (average 185) Width of the ore body : ranging from 120-240 m. (average 180) Depth of the ore body : 25 m MSL

3.3 Mineable Reserves The mineable reserves and total reserves are calculated based on the mineral concession rules. The quantity of the reserves arrived as follows.

3.4 Method of Quarrying Currently the said quarry is working with conventional open cast with bench system method with mechanized mode of operation. Based on the mode and method so adopted and taking into the consideration of geological parameters of the ore body, the quarry pit is so designed such that the height of the bench is kept about 5.00 m (2.50 m x 2 sub benches) max., and the w th o k t 5.00 m, m t 45˚ t o . Benches are advanced side ward and lateral to win the material at lower level /depth.

3.5 Extent of Mechanization List of Quarrying machinery deployed in the quarry along with their capacities, efficiencies and other details are shown in below table:

Sr. Equipment / No. of Engine Size/ No Machinery units H P Capacity 1 Excavator 2 210 2.0 M3 2 Excavator 2 130 3 Rock breaker 2 210 - 4 Tippers 4 10 tonnes 5 Compressor 4 6 Jack hammer 4

3.6 Quarrying Activity Presently the quarry is working with conventional open cast with bench system method with mechanized mode of operation. Based on the mode and method so adopted and taking into consideration of geological parameters of the Charnockite body, the quarry pit is designed such that the height of the bench is kept about 5.00 m max., and the width is kept min 5.00 m, m t 45˚ t o . Two u h t o 2.50 m h ht h, wh t h its ultimate limit, all the two benches will be joined together to form a height of 5.0 m.

Topsoil is sparsely distributed in the area, this topsoil will be removed separately and it will be used for plantation purpose.

As the rock is mainly hard to medium hard in nature, drilling and blasting is required to dislodge/loosen the material from the main rock mass. The broad blasting parameters are determined in subsequent paragraph:

The operation flow chart of the quarry activity is given in the above chapter – II under head Process Description.

Building Stone Quarry of M/s. Thomarappara Bricks & Metals

3.6.1 Explosives Management, drilling and Blasting Blast hole will be, preferably by jack hammer where the diameter is normally 32 mm and the depth of the hole is 2.5 – 2.75 m. Blasting pattern is generally square or rectangle or staggered with burden ranging from 0.75 to 1.00 meters and spacing of 1.00 to 1.20 meters. Usually single/double row of holes is blasted along free face to achieve optimum powder factor, best fragmentation and minimized adverse impacts on account of blasting. Maximum numbers of holes will be blasted at a time in a round are generally limited to 20 to 30 with normal delay detonators to mitigate adverse impacts such as air blast, throw and the ground vibration. Holes are electrically detonated using electric detonators.

Gelatin mixture types of explosives are used for blasting with 20 to 25 percent, proportion of primer/booster cartridges and rest as column charge. About 1 to 1.5 kgs of explosives are loaded in 32 mm diameter holes. And powder factor ranging between 5.0 tons per kgs of explosives is achieved.

3.6.2 Excavation and Crushing The said quarry is a conventional opencast with bench systems and operating in a mechanized mode. The bench height and width is kept at 5m maximum with a pit slope of 450. Subsequent to the drilling and blasting, the material so dislodged/loosen from the rock mass, the big boulders are broken in to small boulders with a help of rock breaker. There after the material is loaded into trucks/tippers of 10 tonnes capacity with the help of the excavator. The loaded material is transported to the crushing and screening unit existing within the quarry area for further process; and despatch to customer.

3.6.3 Topsoil: The amount of topsoil occurs with average thickness of 1 m. This will be removed separately as and when it occurs during the course of quarrying. The topsoil so removed will be stacked separately and will be used judiciously for plantation purpose. Precautions will be taken to limit the height of the top soil dump to 5-6 m in order to preserve its fertility and shelf life. It will be suitably protected from soil erosion and infertility by planting fodder grass and leguminous plants during temporary storage.

The total amount of topsoil existing within the leasehold is calculated as below: Area - 9502 sq.m Depth - 1 m Bulk density - 1.50 9502 X 1 X 1.50 = 14,250 tones.

3.6.4 Mine Waste Management About 1,29,000 tons of mine waste will be generated throughout the mine life and it will be stacked in the area earmarked for it. This waste will be utilized for lying of haul road as well as for backfilling. At the end, this mine waste can be partly utilized as soil base for plantation.

3.6.5 Site Security and Safety Copies of all safety and management documents will be made available to on site, personnel and mandatory training for operations at the Quarry will take place. The Area Coordinator will ensure that operations are consistent with other management plans, terms and conditions of the issued permits, and safety procedures for the Project.

Security signage will be posted at the entrance to the quarry. The remoteness of the quarry and the onsite presence of operations personnel will make perimeter fencing unnecessary. Audible warning systems will be employed for all blasting operations at posted intervals prior to any detonations.

Loose rocks will be properly dressed and nature of rocks and available structural planes will be studied to avoid any slip. Explosives will be stored in safe approved and licensed magazine. Competent blasters (with blasting certificate of competency issued by DGMS) will only handle explosives to avoid any accident. Proper and full proof security will be provided to the magazine to avoid any theft, unauthorized entry etc. proper fencing with sign boards will be provided to separate out the magazine. Blasting and processing operations will be suspended if incursions into the quarry occur. On site monitors for animals will provide warnings if the approach of any animals is noted.

Before the onset of monsoon, drains are cut along the toe of the quarry faces to divert the surface run off. Garland drain is provided at the quarry top to regulate monsoon water and direct the same to the settling ponds / quarry pit to contain the quarry wash off and to avoid the same joining to the adjoining surface water bodies / water courses. It also helps to avert eventual collapses and damages to the quarry faces. The pit will be fenced by barbed wire, such that no habitats can enter the pit and watch and ward is provided round the clock.
