This project will also create additional employment indirectly. 2.5Project Cost Total Project cost: Rs. 50,00,000/- 18 Building Stone Quarry of Mr. Sasidhara Kurup Chapter- III 3.1 Process description The Quarrying operation is carried out in different stages. A flow chart depicting the operations is shown below: OPENCAST METHOD DRILLING & BLASTING 32 mm BLAST HOLE. Nitrate Mixture Explosive BENCH FORMATION 5.0 m HEIGHT & 5.0 WIDTH EXCAVATION BY EXCAVATORS LOADING BY EXCAVATORS / LOADERS TRANSPORTATION BY TRUCKS / TIPPERS DESPATCH TO CLIENT / CUSTOMER The quarry is proposed to work with conventional open cast with bench system method with mechanized mode of operation. Based on the mode and method, taking into the consideration of geological parameters of the charnockite body, the quarry pit will be so designed such that the height of the bench is kept about 5.00 m max. 19 Building Stone Quarry of Mr. Sasidhara Kurup 3.2 REGIONAL GEOLOGY Thiruvananthapuram is the southernmost district of Kerala, bounded by Kollam and Pathanamthitta districts in the north, Tirunelveli and Kanniyakumari districts in the eastand south and the Arabian Sea (Lakshadweep Sea) in the west. The district is situated between north latitudes of 8°17’:8°47 and east longitudes 76°41’:77°16’. The total geographical area of the district is 2192 sq. km.The Western Ghats, which form the eastern boundary of the district as well as the State, are comparatively closer to the coast in this district, than in other parts of the State. Geology of Thiruvananthapuram District The district can broadly be divided into two geological divisions viz. (i) The eastern part represented by the Archaean crystalline rocks and (ii) Western coastal fringe occupied by Tertiary and Quaternary sediments 3.2.1 LOCAL GEOLOGY The area is covered by the Archaean crystalline rocks comprise Khondalite Group, Charnockite Group and Migmatite Group. Khondalite Group is composed of garnetiferous biotite- sillimanite gneiss, with occasional bands of calc-granulite and quartzite, and constitutes the major rock type.Irregular patches of khondalite, veins of pegmatite and quartz are seen within the charnockite. Pyroxene granulite occurs within the khondalite as thin discontinuous lenticular bands conformable to the foliation planes. Migmatites are evenly distributed in the central part of the district as narrow zones within garnetiferous sillimanite gneiss. All these rocks are intruded by a number of dolerite dykes, but their distribution is restricted to the midland region of the district. The applied area is comprised of massive charnockite. 3.2.2 GENERAL DESCRIPTION OF FORMATIONS The geological parameters / features of the ore body as obtained from the field mapping and exploration studies reveal the following: Length of the ore body : ranging from 83 to 125(Avg-104) m Width of the ore body : ranging from 29 to 102 (Avg -65.5) m 3.3METHOD OF ESTIMATION OF RESERVES The estimation of ore reserves is made by conventional parallel cross section method using geological cross section. The geological cross sections are prepared across the 20 Building Stone Quarry of Mr. Sasidhara Kurup strike of the ore body. The area of individual litho units in each and every cross section is calculated separately. The volume between the cross section is arrived on the basis of the average area of production cross section and multiplying sectional interval. And tonnage is arrived at by multiplying by bulk density. Note : Following are the parameters considered for reserve estimation: (i) In the allotted area, the mineral is exposed from the lowermost level of 45m MSL to the top most part of the hill at 80m MSL. Hence, the reserve for proved category has been considered up to 45m MSL. (ii) Bulk Density of Stone and associated minor minerals is taken as 2.5Ton /M3. 3.4 RESERVES OF MINERALS Considering the above parameters and exposures observed in the existing pit in the allotted area, the surface geological plan and geological cross-sections & longitudinal section are prepared. Accordingly, the reserves for Stone and associated minor minerals have been estimated on cross- sectional area method.
