Control method for longwall shearer

The present disclosure generally relates to a method for controlling a shearer (10) in an underground mine. The method comprises setting a first cutting profile (50) including a plurality of desired positions (Di) to be approached by a first cutting drum (12) in a first travel direction (E), advancing the shearer (10) towards the longwall face (2), and generating a second cutting profile (51) including a plurality of desired positions (Ri) to be approached by at least one of the first cutting drum (12) and a second cutting drum (14) in a second travel direction (F) of the shearer (10) based on the set first cutting profile (50), a plurality of actual advancing vectors (vi), and a plurality of shearer orientations (Oi).
