Open pit mining method is one of the surface mining methods that has a traditional cone-shaped excavation and is usually employed to exploit a near-surface, nonselective and low-grade zones deposits.
Open-pit mining is a surface-mining operation in which rocks or minerals are extracted from the Earth by creating an open hole or pit in the Earth's surface. ... waste rock - which lacks sufficient quantities of minerals - and tailings - formed as a result of a mineral separation process. Waste rock is usually piled up at the surface near the ...
Strip Mining involves stripping the surface away from the mineral that's being excavated (usually coal). Soil, rock, and vegetation over the mineral seam is removed with huge machines, including bucket-wheel excavators. Open-Pit Mining is a technique of extracting rock or minerals from the earth by their removal from an open-air pit.
Open pit mining method is one of the surface mining methods that has a traditional cone-shaped excavation and is usually employed to exploit a near-surface, nonselective and low-grade zones deposits.

All over the world, limestone is generally mined from a quarry or through open-pit mining. This method is the easiest way to remove limestone without causing much destruction. In surface mining or open-pit mining, the topsoil and overburden covering the mineral are removed. Then, through the process of drilling, the rocks are broken.
