Claim:
1. A method of monitoring a longwall shearing mining machine in a longwall mining system, the shearing mining machine including a shearer having a first cutter drum and a second cutter drum, the method comprising: receiving, by a processor, shearer position data including information obtained from sensors regarding at least one of a group consisting of a position of the shearer, a position of the first cutter drum, and a position of the second cutter drum; identifying, by the processor, from the shearer position data, profile data obtained over a shear cycle; analyzing the profile data, by the processor, to determine whether a position failure occurred during the shear cycle based on whether the profile data was within normal operational parameters during the shear cycle; generating an alert upon determining that the position failure occurred during the shear cycle.
