Abstract

See full text

A longwall mining system including a longwall shearer having cutting drums. The cutting picks on the cutting drum are monitored for wear using imaging devices mounted to the longwall mining system. Methods for monitoring wear includes a controller receiving image data from an imaging device directed at a cutting drum of a shearer. The controller analyzes the image data to determine a wear level of a cutting pick on the cutting drum. The controller then determines the wear level exceeds a wear threshold and, in response, generates an alert indicating that the cutting pick is worn in response to determining that the wear level exceeds the wear threshold.
