Surface limestone mining. 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 ...
Blasting is the most productive excavation method in hard rock mining. In quarries, to remove the mother rock from in-situ and crush into the desired size is realized by bench blasting method.
