Abstract
A system for monitoring a condition of a pan line associated with a longwall mining system includes multiple pan segments arranged in a successive manner. Adjacently located pan segments are moveably coupled by an interconnecting joint. An underside of each pan segment defines an opening whose axis is parallel to a plane of the associated pan segment. The system also includes a fiber optic shape sensing system that has a fiber optic cable disposed along the multiple pan segments and located within the opening of each pan segment. A controller coupled to the fiber optic cable detects a shape of the fiber optic cable, identifies a position of each pan segment based on the detected shape of the fiber optic cable, and determines if a fault exists in the interconnecting joints between adjacently located pan segments based on the identified positions of respective ones of the adjacently located pan segments.
