Abstract
Methods and systems of monitoring and controlling a longwall mining system. One system includes a shearer including a cutter drum and a sensor mounted to the shearer. The system also includes an electronic controller including a processor and a memory, the electronic controller communicatively coupled to the sensor. The electronic controller is configured to receive vibration data from the sensor and determine a current vibration level experienced by the cutter drum. The electronic controller is also configured to compare the current vibration level to a target vibration threshold associated with a target material seam. The electronic controller is also configured to provide a visual output to an operator of the longwall mining system when the current vibration level exceeds the target vibration threshold, where the current vibration level exceeds the target vibration threshold when the cutter drum of the shearer cuts outside of the target material seam.
