Abstract
A method of monitoring a longwall shearing mining machine in a longwall mining system, wherein the shearing mining machine includes a shearer having a first cutter drum and a second cutter drum, includes receiving, by a processor, shearer position data over a shear cycle. The horizon profile data includes information regarding at least one of the group comprising of a position and angle of the shearer, a position of the first cutter drum, and a position of the second cutter drum. The method also includes analyzing the shearer position data, by the processor, to determine whether a position failure occurred during the shear cycle based on whether the computed horizon profile data was within normal operational parameters during the shear cycle, and generating an alert upon determining that the position failure occurred during the shear cycle.
