Horizon monitoring for longwall system
First 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 an electronic 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 electronic processor, from the shearer position data, profile data obtained over a current shear cycle;
accessing, by the electronic processor, profile data obtained over a previous shear cycle;
comparing, by the electronic processor, the profile data of the previous shear cycle to the profile data of the current shear cycle; and
generating an alert based on the comparison between the profile data of the previous shear cycle and the profile data of the current shear cycle.

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.
