MINING METHOD OF THE WEEK - MINING BY COMBINATION STOPING!!

Combination stoping is a combination of underhand and overhand stoping where it is possible to keep the working face more nearly in a line parallel to the raises and perpendicular to the level. This is a distinct advantage if a stationary or shaking chute is being used to carry the ore to the level, because a large part of the face of the stope is accessible to the chute. This becomes a double advantage if a large output is required. In combination stoping development work is also reduced because levels may be driven far apart, and fewer raises are required than in simple underhand stoping - 911 Metallurgist.
