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 ...

Abstract. Open-pit mining operations involve loading and hauling of material from the pit to the processing plant or waste dump depending on the ore grade. These two activities account for more than 50% of total operating costs of the mine. There are several loading and hauling systems that are employed depending on the geometry of the ore body.

Open pit mining. One precondition for open pit extraction is that the ore body extends up to the surface or is not covered by an excessively thick layer of soil or rock. In most open pit mines, ore is extracted by so-called benching. The mining method is based on the ore being extracted in "benches" at successively lower levels.
