As the demand for energy places an ever-increasing pressure on the coal mining industry to produce more coal, methods for underground mining that will increase productivity with a concurrent increase in safety are being sought. Removing the machine operator from his station on the continuous miner and placing him at a safer location behind the machine while retaining control functions by way of an umbilical cable or a radio link is an important first step. The purpose of this investigation was to provide the first step to total automation of the entire mining cycle and to provide hands-off control of the mining machine for a specific number of sump shear cycles.
