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 ...

• The physical environment under which mining equipment operates is less than ideal. • The operating environment of the mine is dynamic with many unknowns that can affect the equipment utilization drastically. In this study, OEE of shovels and trucks have been considered since they are the main equipments for the most of the Open Pit Mines.
Methods for estimating productivity and costs, and dependent equipment selection process, have needed to be increasingly reliable. Estimated productivity and costs must be as accurate as possible in reflecting actual productivity and costs experienced by mining operations to accommodate the longterm trend for diminishing commodity prices, For loading and hauling equipment operating in open ...
