Adaptive control of longitudinal tilt in long working face development system

摘要

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.
