Abstract:
Methods and systems of controlling a pitch angle of a shearer. A controller receives a sensor signal indicative of the pitch angle of the shearer, and receives a target pitch profile defining a plurality of target pitch angles for different sections of a mineral face. The controller determines a pitch difference between the pitch angle and a target pitch angle of the shearer, determines a pitch correction height corresponding to a new height for a floor cutter of the shearer based on the pitch difference, and changes a height of the floor cutter based on the pitch correction height.

Claim (Index 7):
The method of  claim 1 , further comprising:\n storing in a memory, as historical corrective actions, the pitch correction height, the pitch difference, and an achieved change in pitch angle resulting from changing the height of the floor cutter based on the pitch correction height; and during a later shearer pass, determining a pitch compensation value for use in calculating a later pitch correction height based on the historical corrective action.
