Abstract
A method of controlling a longwall mining system, the longwall mining system including a longwall shearer, a conveyor, and a plurality of roof supports, such that the method includes creating, by a controller, a load profile of the conveyor representing a distribution of mineral along a length of the conveyor, calculating, by the controller, a desired change in the load profile based on the load profile of the conveyor, and controlling, by the controller, the longwall mining system to adjust the distribution of mineral on the conveyor based on the desired change in load profile.
