Blasting Of Limestone Deposit

Limestone extraction – underground mining techniques ...

All over the world, the limestones are generally mined from a quarry or the open pit mining. It is the easiest way to remove the limestone without causing much destruction. In surface mining or open pit mining, the top soil and the overburden covering the mineral is removed. Then by the process of drilling the rocks or broken.

H BLASTING IN SURFACE EXCAVATION

Cast Blasting When overburden is removed from a coal or mineral deposit it is generally cast to a waste dump by draglines, or removed by loaders and trucks. Cast blasting is the controlled placement of overburden into the previously mined cut resulting in a reduced volume or overburden material for the dragline to handle. 19
