The intensification of the transportation processes of mined minerals is one of the key factors in solving the problems of increasing the productivity and competitiveness of the extractive industries. The processes of transportation of mining minerals are associated with their spatial movement by means of belt conveyors. Existing tools for assessing the weight of mining minerals transported by conveyors are based on the use of strain gauge methods and means of control, which allow weighing of mining rocks with acceptable accuracy at a conveyor belt speed of up to 5 m/sec. For conveyors with a high length (more than 10 km), such speed and weighing speed is unacceptable. Therefore, the development of methods and means of controlling the weight of rock transported by a conveyor at high speed is an urgent task. This paper is devoted to the substantiation of the dynamic method of controlling the weight of cargo transported by a belt conveyor based on an assessment of the dynamics of acceleration and deceleration of the rotor of a driving electric motor in steady–state operating conditions.
