The definition of a open pit mine is "an excavation or cut made at the surface of the ground for the purpose of extracting ore and which is open to the surface for the duration of the mines life." To expose and mine the ore, it is generally necessary to excavate and relocate large quantities of waste rock.
Open Pit Mining Methods
09/04/2017· 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.
