DEF

A cutter-loader for continuous mining in longwall faces.

OBS

Its main cutting unit is the trepanner wheel with cutting arms, one at each end of the machine to enable it to cut in both directions on the face. Also fitted are a vertical, back-shearing jib, a floor-cutting jib, duplicated to enable cutting in either direction and, if necessary, a roof-cutting disc. The machine is used in conjunction with an armoured flexible conveyor on a prop-free-front face; suitable for seams between 3 and 4 ft thick, though it can work in thicker seams if the top coal falls freely.
