Mining

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 excavators 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 …Web
