Openpit 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 openpit mining. The removal of this material is known as stripping. The strippingpit limits must be extended beyond the limits of the ore pit to provide a bench, and the pit

Openpit mining is much safer than shaft mining. In underground mining, the threat of a cavein or release of toxic gas is a constant concern. When shaft mining was the most common method of ore extraction, thousands died in caveins, gas events and accidents involving equipment. In 1907 alone, more than 3,200 deaths related to mining occurred.
