ABSTRACT:
A mine roof-bolter machine having an extensible conveyor running therethrough operates behind a continuous miner machine. As the continuous miner advances, the roof-bolter advances from position-to-position while installing roof bolts and plates, and the extensible conveyor gives and takes the slack between the continuous miner and the roof bolter and feeds mined material to a surge car behind the roof bolter.
