Abstract
Systems and methods for operating a mining machine. One system includes a controller, a stationary object, and a radar device. The radar device transmits radio waves toward the stationary object and detects reflections of the radio waves. The controller obtains timing information regarding the radio waves and the reflections. Based on the timing information, the controller is configured to determine a first distance between the radar device and the stationary object before sumping the mining machine into material and a second distance between the radar device and the stationary object after sumping the mining machine into the material. The controller is also configured to determine a sump depth of the mining machine based on the first distance and the second distance, compare the determined sump depth to a predetermined sump depth, and perform at least one automatic action when the determined sump depth does not satisfy the predetermined sump depth.
