Mining - Open pit mine ArcelorMittal

Open pit mine. Most iron ore mining operations use the ‘open pit’ method, where miners drill into the rock and blast the ore-bearing material loose with explosives. Huge Crushers are then used to gather the loosened ore. To mine metallurgical coal, which will later be turned into coke, it’s usually necessary to sink vertical mine shafts to access coal which is deposited in layers or ...

Open-Pit Mining Methods

09/04/2017  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 limits of the ore pit to provide a bench, and the pit ...
