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. 3.2 REGIONAL GEOLOGY The district has in general an undulating topography with regional westerly slope .Thrissur district can be broadly in to four geological belts. 19 Building Stone Quarry of Mr Abdu Rahman *Charnockite belt which is wide spread and most prominent in the district * Gneissic belt represented by biotite gneiss,hornblende biotite gneiss and quartzo feldspathic gneiss *Granitic gneiss (PGC) restricted to the south eastern part *The quaternaries of the coastal tract. 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. The upper part of the rock is weathered, giving rise to a thin veneer of soil, thickness of which does not exceed 1.0 m within the quarry site. 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 39.5 to 146.7 (Avg-103.65) m Width of the ore body : ranging from 97.8 to 101.8 (Avg -99.8) m 3.3 METHOD 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 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 70m MSL to the top most part of the hill at 115m MSL. (ii) Bulk Density of Stone and associated minor minerals is taken as 2.5 Ton /M3. 20 Building Stone Quarry of Mr Abdu Rahman 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.
