A system and corresponding method of monitoring a longwall shearing mining machine in a longwall mining system, where the shearing mining machine includes a shearer having a cutter drum, the method includes obtaining, by a processor, desired pitch angle information, and receiving, by the processor, a pitch angle indicative of a current pitch position of the shearer. The method also includes determining, by the processor, whether the pitch angle is within a desired pitch angle range, and controlling, by the processor, a position of the cutter drum based on whether the pitch angle is within the desired pitch angle range. The desired pitch angle range is based on the desired pitch angle information.
