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 limits of the ore pit to provide a bench and the pit
