Abstract
The recent literature concerned with the monitoring, remote control and automation of longwall mining equipment is reviewed. The mining equipment considered is the coal cutting machine, the armoured face conveyor, and the powered supports. Some emphasis is placed on the status of transducer and instrument development for monitoring applications in the three problem areas of roll control, horizon control and face alignment control. Other topics considered are control systems for roof supports, data transmission and handling, and control systems for mining equipment. It is concluded that the complete automation of longwall mining is not a viable proposition for the foreseeable future.
