Surface Mining | Surface Mining | Mining Surface mining is the predominant exploitation method worldwide In the USA, surface mining contributes about 85% of all minerals exploitation (excluding petroleum and natural gas) Almost all metallic ore (98%) and non-metallic ore (97%), and 61% of the coal is mined using surface methods in the USA (Hartman and Mutmansky, 2002)...
i) Mechanical excavation methods; such as Open 3 Surface mining: Is a type of mining in which soil and rock overlying the mineral deposit (the overburden) are removed Surface mining is the predominant exploitation method worldwide Surface mining requires large capital investment (primarily expensive transportation equipment), but generally results in: - High productivity (ie, high output rate of ore)...
SURFACE MINING METHODS Strip mining is ideally applied where the surface of the ground and the ore body itself are relatively horizontal and not too deep under the surface, and a wide area is available to be mined in a series of strips Typical examples of this type of mining are the larger tonnage coal mining operations in Mpumulanga Favourable conditions are:...

Surface mining Surface mining, including strip mining, open-pit mining and mountaintop removal mining, is a broad category of mining in which soil and rock overlying the mineral deposit (the overburden) are removed, in contrast to underground mining, in which the overlying rock is left in place, and the mineral is removed through shafts or tunnels Surface mining began in the mid-sixteenth century [dubious ....
