Abstract: The open pit mining of mineral deposits (first of all, the development of coal deposits) is of great importance for the economy of Russia as a whole, as well as for individual regions, including the Kemerovo region - Kuzbass. In 2018, 255.3 million tons of coal were extracted in Kuzbass, of which 165.8 million tons (65%) were produced by open-cast method. There is no reason to believe that the part of coal extracted at open-pit mines will decrease. Taking into account that the Russian Federation Government Decree No. 14-r of January 24, 2012 approved the Long-Term Development Programme for the Coal Industry of Russia until 2030, which includes, among other things, the Subprogramme "Development of Production Potential of Existing Coal Production and Processing Facilities and Development of New Coal Deposits", one of the objectives of which is the introduction of advanced coal production technologies, and the Subprogramme "Ensuring Technological Development of the Industry and Strengthening the Scientific and Technical Base of the Russian Coal Industry", it is safe to say that it is necessary to develop the key areas of this Program, in particular, the development of new and existing technologies and types of equipment aimed at improving the efficiency of coal mining, preparation, processing and integrated use and increasing the added value of coal products.
Road transport currently dominates the transportation of overburden and coal at open-pit mines. Its share has been steadily growing since the 1970s. This is due to objective reasons, firstly, rather limited area of application of railroad transport: considerable range of transportation, large cargo turnover and shallow depth of the mine. First, it concerned the depth of the open-pit mines, because when deepening the quarry by one bench it was necessary to extract significant volumes of overburden to ensure the placement of transport berms because of the large radius of curvature of the railway track, which reached 200 m. Therefore, given the fact that the open-pit mining had gone to great depths at almost all enterprises, there was a widespread abandonment of rail transport for in-quarry transport in favour of dump trucks.
That is why the problem of research and description of key characteristics of quarry transport at open pit coal mining is actual.
