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:

are opencast methods where the coal seams are rela-tively shallow andthick, andpanel andlongwall mining methods fordeeper coalseams. Thearea ofapplication ofopencast methods islargely determined bythe size ofthe coal deposit and the coal-to-waste ratio. For longwall andpanel mining, theareas ofapplication are lessclearly defined.
