A system for controlling the speed of travel in a long-wall mining - shearer loader

摘要

A shearer loader - a system (100) for the removal of material along a degradable distance relative to a degradation environment (102) comprises a rail arrangement (114) for supporting the movement of a shearer loader - support frame (104) thereon. The system (100) further comprises a transport motor (112), which is structured and arranged for this purpose, the roll loaders - support frame (104) along the rail arrangement (114) to move. The system (100) has a rotatably driven cutting device (106), the relative to the roll loaders - support frame (104) is positionable. The system (100) further comprises an actuator (108) which, due to the roll loaders - support frame (104) is supported, in order to change a cutting height of the cutting device (106). The system (100) further comprises a control unit (120), comprising a speed of the roll loaders - support frame (104) on the basis of a speed of advance of the cutting device (106), a maximum speed of the roll loaders - support frame (104), a current level of the cutting device and a desired height of the cutting device can be controlled. Optionally, the control unit (120) of the further the speed of the roll loaders - support frame (104) on the basis of a predetermined stopping distance at that of the roll loaders - support frame (104) controlling.
