ABSTRACT:
The trailing drum of a double-ended ranging drum shearer is steered in a seam by producing an algorithm which determines, as a result of information derived from signals from the machine dependant on its tilt, direction and amount of movement along a face being cut. The height of the leading drum is used as a reference from which to determine the optimum position of the trailing drum in order that a constant quality of desired mined material is obtained.
