- 1. A Brief Report On Baghai LimestoneMine Prism Johnson Limited
- 2. Introduction- Prism Johnson Limitedis a prominent cement manufacturer with cement production capacity of 5.6 MTPA in central India. It has integrated cement plant in Satna district of Madhya Pradesh. to cater the demand of basic raw material (i.e. Limestone) of integrated cement plant Prism Johnson Limited has various mining lease in and around of cement plant. Limestone mine lease details are as- 1. Hinauti & Sijhata Limestone Mine ( Leased Area- 772.067 Ha) 2. Hinauti & Sijhata Limestone Mine ( Leased Area- 99.416 Ha) 3. Mendhi Limestone Mine ( Leased Area- 117.594 Ha) 4. Baghai Limestone Mine ( leased Area- 512.317 Ha) Geologically, this area forms part of the Rewa Plateau belonging to the Upper Vindhyan Super group of rock formations in Indian stratigraphy. The Vindhyan formations are broadly classified into lower calcareous and an upper arenaceous facies. The upper arenaceous rocks however, have a calcareous horizon - the Bhander Limestone varying in thickness from about 5 to 15 mtrs. The Limestone deposit of the area belongs to the Bhander series. The general trend of Bhander Limestone is East – North-East to West – South-West having low Southerly dipping of less than 50 .

Leased area falls in toposheet no. 63H/2. Mine Lease area is spread in between latitude 24°33’14’’ to 24° 34’44’’ in north direction and longitude 81°01’47’’ to 81°04’20’’ in east direction. General level elevation is range from 291 MRL to 324 MRL. Presently Baghai Limestone Mine has two active mining pits B-4 & B-9, in B-4 Pit general stratigraphy is Soil, Intercalated Rock, Limestone with various discontinuity distribution is the area. Whereas B-9 Pit general stratigraphy is alluvial soil, intercalated rock then limestone, limestone trend is continuous from north direction to south direction with approx. 4°- 5° dipping towards south.

B-4 Pit B-4 Pit SoilDump B-4 Pit OB Dump Baghai Limestone Mine- B-4 Pit- • An area as shown in map is developed for limestone raised followed by alluvial soil cutting of around 1-2m and separate staking done in B-4 Pit soil dump • As per stratigraphy intercalated rock around thickness of 7m thickness after alluvial soil is being encounters, excavated and stacked in B-4 OB Dump. • After intercalated rock, Limestone encounters having thickness around 7-9 m. • All mining is being done by fully mechanized system of mining followed by Drilling, blasting, loading and hauling through systematic developed mine haulage roads. • Haul road is connected with baghai village road which is RCC road, through RCC road Limestone is being haul through to PCL crusher or stock • Soil Dump is of 10-12m height which is well stablished and stabilization through long root grass planation for binding the material together to enhance the slope stability

Limestone (thickness- 14- 15m) is encountered, which is mined out through systematic development of 2 numbers of limestone bench. 1st Limestone bench height is 8-9m and 2nd limestone bench is proposed to be of 6-7m. • All mining is being done by fully mechanized system of mining followed by Drilling, blasting, loading and hauling through systematic developed mine haulage roads. • Boulder generated through blasted in resized through Rock breaker • B-9 Pit is fully developed through Contractor working.
