Abstract
Systems and methods are provided for detecting face creep of a longwall mining system. The system includes a detection device mounted in a maingate roadway and coupled to the detection device. The controller determines the position of the beam stage loader-armored face conveyor interface based on a signal from the first indicator device, determines a position of a maingate line based on a signal from a maingate indicator device, and determines a position of a belt conveyor based on a signal from a belt conveyor indicator device. The controller further determines a first distance between the position of the beam stage loader-armored face conveyor interface and a maingate line, and a second distance between the position of the belt conveyor and the maingate line. The controller generates an indication of face creep based on the first distance and the second distance.
