The article deals with the actual issue of reducing the energy consumption of the mining enterprises conveyor transport system. The analysis of energy loss by conveyor belt during transportation of bulk load is given. A comparative analysis of energy losses in the cases of regulation and non-regulation of the speed of the conveyor belt is given. It was found that when regulating the speed of conveyor belt in the case of reducing the value of the load flow entering to the conveyor by half the loss of electricity for the transportation of load is reduced by 30 % compared to the unregulated speed of the belt. The energy efficiency criterion of the conveyor transport system is determined, which coincides with the specific energy capacity equal to the ratio of the average energy capacity of the transportation of load to the transport system average carrying capacity. It has also been established that for conveyor transport systems conveyor– bunker–conveyor, taking into account the downtime of conveyor equipment while regulating the speed of conveyor, energy losses are reduced by 23 %. The research results can be used to create a computer control system for the operation of conveyor transport systems.
