A systemwide approach to minimize the operational cost of ...

Dec 12, 2018 The production cycle of opencast coal mines generally includes drilling, blasting, loading, hauling and coal preparation activities. Individual optimization of these activities does not mean that the whole system is optimized. This paper proposes a cost model considering all activities in mining cycle and systemwide approach to minimize the total mining cost of bench production.

OpenPit Mining Methods

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 ...
