A push-button mining machine with a potential range of 1,000 ft (304.8 m) into a seam from the highwall, a maximum production of some 600 st (544 t) per shift, and a recovery of 65% to 75% of the coal within the reach of the machine. This unit is a continuous miner working controlled from outside the seam of coal. The operator can control both the vertical and horizontal direction of the cutting heads as shown on an oscilloscope screen. As the cutting head advances into the coal seam, it drags a series of conveyor sections behind it, which in turn deposit the coal into a truck. Krumlauf
