ABSTRACT:
A universal ripper miner used to cut, collect, and transfer material from an underground mine working face. The cutter head has a single large cutting bit attached to its periphery and moves in an arcuate cutting motion in a cycle less than 270.degree.. At each cutting cycle the bit's depth of material penetration is initially zero, increases to its maximum depth at about midway, and decreases to zero depth as it exits. Drive members, such as hydraulically actuated pistons, provide for this movement of the head/bit. Constructed as part of the cutting head adjacent to the bit, a hopper-type member with a partially opened upper section acts to continuously collect and transfer cut material from the mine face. A mechanically or gravity actuated door is at the end of this hopper member remote from the cutting head allows the cut material to be transferred to a lower conventional material handling system. The cutter head and its mounted frame can be moved in a direction perpendicular to the direction of the cutting head during its cutting cycle to allow a new adjacent cutting cycle to be performed. Also, after a desired number of cycles have taken place, the frame and cutting head can be advanced into the mine working face by a third power source.
