Abstract: The design solutions for the development of the Sukhoi Log gold deposit provide for a quarry with the transportation of the ore mass by diesel dump trucks. Transportation costs exceed 25% of the total cost. Due to the fall in gold prices and the increase in the cost of diesel fuel, transport services significantly reduce the efficiency of the enterprise. Based on the simulation method of modeling transport schemes and technical and economic calculations, it was found that it is possible to avoid this trend by replacing diesel vehicles with diesel trolley trucks. For this technology, it is necessary to justify the organizational scheme of transport works, which includes the scheme of electrification of both the quarry itself and the waste ore facility. The article proposes a variant of the scheme of phased electrification of the transport scheme with a breakdown into 5 stages of 6 years each. In the process of deepening the quarry, the total length of the transport network increases, and the number of transport units increases accordingly. In order to fulfill the planned indicators for ore extraction, it is necessary to ensure such a performance of the transport system that would allow the delivery of ore mass to the surface for further processing and disposal synchronously with its the breaking and loading. The calculation of the planned indicators of loading and hauling the ore mass using diesel trolley transport should be justified by the necessary high-speed modes of movement of transport units both in the mode of operation of the internal combustion engine and in the mode of electric traction. To do this, you need to set the technological parameters that determine the effectiveness of the proposed technical solutions. As studies have shown, such a parameter is the speed of movement of transport units, which in turn depends on the rolling resistance of the vehicle. In addition, it is necessary to propose an effective trolley network system, taking into account the power consumption over the years of inventory development.
