What Is Open Pit Mining? | An Underground Miner
Open-Pit vs. Strip Mining. Strip mining is a surface technique where workers clear vegetation, waste rock, and overburden from the ground. Typically, miners use these operations for extracting rock and coal from just below the surface. Open-pit mining differs as workers excavate large landscapes on deeper slopes, separated by "benches."

Open-Pit Mining Methods
Open-pit mining methods are applicable to mining ore deposits that apex at or near the surface. If the deposit apexes below the surface, the overburden and barren capping overlying the ore must be removed in advance of open-pit mining. The removal of this material is known as stripping. The stripping-pit limits must be extended beyond the ...
