Annotation: One of the most important components of the mining industry is the delivery of cargo by conveyor transport. However, modern transportation methods are not sufficiently efficient in terms of energy consumption. This is due to the uneven flow of cargo from the lava during the work shift, which leads to three times the normative values of energy consumption. The present work is devoted to the urgent problem of finding ways to reduce the energy consumption of conveyor transport with variable cargo flow from lava in order to reduce the cost of coal production. Based on the developed virtual model, the dependences of the total energy consumption of the conveyors are obtained for various modes of belt speed control. It has been established that the most appropriate is the use of three-speed discrete control with criterion for reducing total energy consumption with an investment of minimum investment costs. An increase in the number of operating speeds of more than three does not give a significant increase in additional savings.
Keywords: conveyor transport, cargo flow, coalface, unevenness, regulation, modeling, workflow, energy consumption.
