  • Limestone extraction underground mining techniques

    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 broken.
