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 associated with the shearer based on the vibration data. The electronic controller is also configured to compare the current vibration level to a vibration threshold. The electronic controller is also configured to, in response to the current vibration level exceeding the vibration threshold, adjust a cutting parameter for the cutter drum of the shearer. The electronic controller is also configured to control the cutter drum with the adjusted cutting parameter.
