FIELD: mining; machine building.
SUBSTANCE: systems and methods for controlling a conveyor in a mining system. Conveyor includes chain, first sprocket, second sprocket, drive mechanism, first sensor, second sensor, and controller. Method includes receiving a first signal associated with a characteristic of at least one of a first sprocket or a second sprocket, determining a characteristic value of at least one of a first sprocket or a second sprocket based on a first signal, receiving a second signal associated with the characteristic of the chain and determining characteristic values of the chain based on the second signal. This method further includes comparing the characteristic value of at least one of the first sprocket or the second sprocket and the chain characteristic value and determining the chain sag value based on said comparison.
EFFECT: improved determination of chain sagging.
