COST IMPACT :-

Additional Cost i.e. Mining, Land cost ,High Grade limestone cost ,Pet cock cost, Modification in Plant etc.

Thus total 481.42 Rupees /tonnes will be increased till the end of mining .

OTHER IMPACT :-

1-Landuse pattern will be disturbed due to stacking of threshold value limestone 2- Decreased crop production and increased environment load near by area. 3-Fuel consumption may also increased. 4- Capital Investment for Land acquire & to fulfil land Looser Demand , Necessary Permissions etc. will increased cost of mining & end product. Which is indirect loss of consumer.




CONCLUSION :-

1- During Exploration &Mining, it is observed that our limestone deposits have minor layer of shale which decreased CaO % in irregular pattern. Similarly MgO % in our deposits has been increased with depth. Which is above 4 to 11%. There for blending of low grade limestone increased mining cost. 2-Separate stacking ,Its utilisation in kiln, Blending with high grade limestone of threshold mineral are costly. Which effect cost of our end product. 3- Environmental parameters will be also effected . 4-There is no sufficient limestone deposits to meet our high grade limestone in nearby mines/lower Vindhyan deposit near Maihar, Satna &Katni belt. 5- We are unable to use 100% available limestone of threshold value due to quality & rate, constraint of cement in market. Therefore we request that limit of threshold value of limestone in lower vindhyan super group may redefined upto Cao-36% & MgO-3.0to 3.3% to meet the cement industry need.
