FIELD: measuring.
SUBSTANCE: in the preferable version of the invention, the data on change of the position of the movable element of the tensioning device of the belt conveyor in comparison with the reference value of the position and/or with the reference pattern of values are used to determine the occurrence of the abnormal source of concentrated resistance to the movement of the conveyor belt.
EFFECT: high accuracy of determining anomalous source of concentrated resistance to movement of the conveyor belt as a result of emergency jamming in the belt web of a foreign ore-clogging object or a piece of ore, which leads to damage to the belt, in particular to a longitudinal cut (rupture) of the conveyor belt.
