This project will also create additional employment indirectly. 2.4 Project Cost Total Project cost: Rs. 50,00,000/- 18 Building Stone Quarry of Mr. Vargheese Kurian Madapparambil 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. Vargheese Kurian Madapparambil 3.2 REGIONAL GEOLOGY Geologically the district can be divided into three major belts in a north-south direction – (i) Peninsular Gneissic Complex in the north and (ii) Charnockite Group of rocks in the south and (iii) Migmatitic Complex in between. The oldest rock of the area belongs to Peninsular Gneissic Complex represented by granite gneiss. The rocks are well foliated and show regional folding as well. Khondalite group is represented by calc- granulite and quartzite. These rocks are seen as linear bands, lenticular bodies or enclaves, mostly within the gneissic terrain. The Charnockitic Group comprises of pyroxene granulite, magnetite quartzite and charnockite among which the charnockite is dominant and widespread. Pyroxene granulite and magnetite quartzite occur as linear bands of a few metres width and a few tens of metres in length within the gneissic terrain. They are aligned generally parallel to the trend of foliation. 3.2.1LOCAL GEOLOGY The area is covered by Charnockite which occurs as continuous rock unit covering the hilly region in the south and northwest. It is mostly massive but gneissic varieties are also seen, with intermediate to acidic in composition. Central, northeast and southeast parts of the district are dominated by rocks of migmatitic complex comprising of biotite gneiss and hornblende-biotite gneiss (composite gneiss). While the south central part around Pynavu and Thodupuzha is occupied by biotite gneiss, the north eastern and south eastern parts are covered by hornblende biotite gneiss. The biotite gneiss has plenty of restites of older Khondalite and Charnockite Groups of rocks occurring as lensoidal and linear bodies, conformable with the trend of foliation. Granite emplacement is seen around Munnar, Devikolam and along the eastern boundary. Both pink and grey varieties are observed. The rock in the permit area is massive charnockite.

The geological cross sections are prepared across the 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 135m MSL to the top most part of the hill at 150m MSL. Hence, the reserve for proved category has been considered up to 135m MSL. (ii) Bulk Density of Stone and associated minor minerals is taken as 2.5Ton /M3. 21 Building Stone Quarry of Mr. Vargheese Kurian Madapparambil 3.6 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.
