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. Building Stone Quarry of Mr. Thambi B.A 3.2 REGIONAL GEOLOGY The district has in general an undulating topography with a regional westerly slope. Thrissur district can be broadly divided in to four geological belts. Charnockite belt which is wide spread and most prominent in the district Gneissic belt represented by biotite gneiss, hornblend biotite gneiss and quartzo felspathic gneiss. Granitic gneiss (PGC) restricted to the south eastern part and the quarternaries of the coastal tract. (*Secondary Source :- District Resource Map, Thrissur district, Published by geological survey of India.) 3.2.1 LOCAL GEOLOGY The main rock type in the quarry site is charnockite, consisting of pyroxenes, feldspars, quartz and occasional biotite. Two sets of joints are seen traversing the rocks, often rendering the rock mass as elongated and isometric blocks of different shapes and sizes. As a result, the quarry products cannot be used as blocks of dimension stone. Thin veins of pegmatite are seen intruding the charnockite mass. 3.3 GENERAL DESCRIPTION OF FORMATIONS Geological parameters / features of the ore body as obtained from the field mapping reveal the following: Length of the ore body : ranging from 42 to 65 (Avg- 53.5m) Width of the ore body : ranging from 52 to 163 (Avg-107.5 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 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 tonnage is arrived at by multiplying by bulk density. Building Stone Quarry of Mr. Thambi B.A Note : Following are the parameters considered for reserve estimation: (i) In the allotted area, the mineral is exposed from the lowermost level of 30m MSL to the top most part of the hill at 40 m MSL. Hence, the reserve for proved category has been considered up to 30m MSL. (ii) Bulk Density of Stone and associated minor minerals is taken as 2.5Ton /M3. 3.6RESERVES 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 Geological Reserves:- Table 4- Section wise Geological Reserve Estimation Proved Reserves Area of cross Influence Section line Vol. in m3 Total Ton section (m2) length (m) A-A' 513.744 16 8,219.904 20,549.76 B-B' 1,057.351 14 14,802.91 37,007.285 C-C' 327.853 18 5,901.35 14,753.385 Total 72,310 Mineable Reserves :- To estimate the minable reserves, the reserves blocked under 7.5 statutory barriers and due to formation of systematic benches up to Ultimate Pit Limit have been considered.

The mineable reserves are arrived after deducting the reserves locked in mines barrier along the boundary in compliance with Metalliferous Mines Regulations 2015. Summary of Geological and mineable reserve is given below.
