Automated continuous roof support.
Coal Age 1975 Jul; 80(8):115-117
The Bureau of Mines continuous roof support program is directed at minimizing factors that limit production. The two immediate goals of the program are to develop a reliable continuous miner that will bolt the roof as mining proceeds and to develop simple, reliable, automated high-speed bolting equipment that can drill holes and place bolts without requiring an operator to be in the immediate area of the bolt installation.
