摘要： A method of controlling a shearer is disclosed. The shearer may be configured to travel along a longwall face to extract material with a first cutting drum and a second cutting drum. The method may include setting a first cutting profile including a plurality of desired positions (Di) to be approached by the first cutting drum in a first travel direction (E). Further, the method may include determining a plurality of actual advancing vectors (vi) indicating a change of a position of the shearer resulting from advancing the shearer towards the longwall face. The method may also include determining a plurality of shearer orientations (Oi) along the longwall face. In addition, the method may include generating a second cutting profile to be approached by at least one of the first cutting drum and the second cutting drum in a second travel direction (F) of the shearer.
