| description | 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 a cutter drum of 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 detect an impact event associated with the cutter drum of the shearer based on the comparison and generate an impact event indication associated with the impact event. |
