Fig.1, above shows an illustration of a open pit surface mine.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.
