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.

determining a conveyor motor stop time;

determining whether a relocation has occurred; and

when the relocation has occurred;

determining a cut end time based on conveyor motor stop time and the relocation;

storing, in a memory coupled to the electronic processor, the cut start time, the cut end time, the boom height data, and the power consumption data; and

adjusting the operation of the mining machine based on the cut start time, the cut end time, the boom height data, and the power consumption data for at least one of the plurality of cut locations.

2. The method of claim 1 , wherein determining whether a relocation has occurred includes determining whether a conveyor motor is off; and

when the conveyor motor is off

determining whether or not a relocation threshold has been met; and

when the relocation threshold has been met;

determining whether a conveyor time threshold has been met; and
