Abstract:
Systems and methods for monitoring extraction height and volume of material extracted for a mining machine. The method includes operating the machine using a shearing motion at a plurality of cut locations. The method includes receiving boom height data and power consumption data. The method includes determining a cut start time, based on a conveyor motor start time, and a conveyor motor stop time. The method includes determining whether a relocation has occurred. The method includes, when the relocation has occurred: determining a cut end time based on conveyor motor stop time and the relocation; and storing, in a memory, the cut start and end time, and the boom height and power consumption data. The method includes adjusting the operation of the mining machine based on the cut start and end time, and the boom height and power consumption data for at least one of the cut locations.
