Longwall system face alignment detection and steering

摘要

Systems and methods are provided for detecting face alignment and face steering of a longwall mining system. The system includes a detection device mounted in a maingate roadway and a first indicator device mounted on a shearer of the longwall mining system to indicate a position of the shearer to the detection device. The system further includes a controller coupled to the detection device. The controller determines a shearer path of the shearer as the shearer moves along an ore face. The shearer path is determined based on a signal from the first indicator device received by the detection device. The controller generates an indication of face alignment based on the shearer path.
