x 3.5m to 5m x 5m, that are large enough to permit the use of most mining
equipment.
     The number of drifts required and their length is determined by the mining
method and the dimensions of the ore body. Although drifts can slope at differ-
ent angles, and can follow the ore body, they normally incline at less than 7:1.
     Excavating of drifts and ramps are standing objects in the mine’s schedule.
Development work is often done by special teams which use their own equip-
ment. One method used for transporting ore is a conveyer belt running along an
inclined, small diameter tunnel.

                       Ore, rock and mining methods

      The underground mine aims to recover minerals contained in the bedrock.
The ore body is the volume containing valuable minerals, while the rock around
is waste. In geological terms, rock around the ore body is called the host rock.
Waste is useless matter, which miners try to leave in place. Waste dilutes the
ore, and reduces the grade in run-of-mine ore.
