Abstract: Transportation costs for the development of open-pit deposits amount to 25% or more of the total cost of operating the mine depending on the depth of the quarries. Therefore, reducing these costs is one of the important ways to improve the efficiency of open-pit mining. As the depth of development increases, the share of transportation costs in the volume of operating costs increases. Currently, the depth of the quarry for the development of the Sukhoi Log gold deposit has reached a critical value for the use of motor transport, so the question arose of finding an alternative to the use of diesel dump trucks. A complicating factor is the constant increase in the cost of diesel fuel. In the immediate vicinity of the mining enterprise is the Ingalinskaya HPP, which produces relatively cheap electricity. A possible alternative to diesel transport could be diesel trolley truck, in which a significant proportion of the diesel fuel consumed could be reduced by the use of electric traction. The use of diesel trolley trucks for the delivery of ore could allow not only the reduction of operating costs, but also an increase in the intensity of haulage, based on the experience of using these types of transport at related enterprises. An increase in the intensity of haulage, in turn, will reduce the number of transport units necessary to ensure a given productivity of the quarry for the ore mass, which in turn will lead to a reduction in harmful emissions generated during the operation of internal combustion engines and the volume of dust generated. This will improve the mine atmosphere. To ensure the efficient operation of the transport system, it is necessary to create an appropriate infrastructure, which consists in laying trolley lines both inside the quarry and on the surface and rebuilding transport berms. This article is devoted to substantiating the possibility of replacing motor transport with diesel trolley trucks during the development of the Sukhoi Log gold deposit by a deep quarry.
