:
the term "mining"; non-metallic minerals; the tendency in mining; the exploitation of lower-grade metal-bearing substances; the type of mining; the problem of depth; the mining method; the metal-bearing mass; yertical and horizontal mine workings; to vary in shape, dimensions, location and function; to classify mine workings
6. drive :
1. Sloping exploratory shafts are usually driven in the mineral.
They produce mineral during driving and it can be sampled and
tested.
2. One of the main parts of a mining machine is the drive which
can work either on compressed air or electricity.
3. Many miners can drive combines which are widely used un
derground now. They are called combine drivers.
