A conveyor having an intake on the ground between the base and the cutter and extends back away from the face, normally through the base. Actuators connected between the cutter, arm, support, conveyor, and base move the cutter over the face to cut rock therefrom and convey the cut rock back away from the face. A drilling apparatus including a drilling unit for making a hole extending along a bore axis and another unit for setting a rockbolt in the hole thus drilled is carried on the arm and engageable with the ceiling immediately adjacent the face. The cutter is engageable with the floor to support the arm thereon while the drilling apparatus is boring in the ceiling.
