摘要：Open coal mining companies in Kuzbass (Western Siberia, Russia) constantly face challenges to increase the economic efficiency of mining operations, reduce coal losses and increase profitability. One of the ways to increase the efficiency of open pit mining is to improve the technology for the development of coal-bearing zones of quarry fields on complex structured inclined and steep deposits. At present, the projects for promising deposits have been completed, and a number of operating open pits conduct the development of coal-bearing zones along their entire width by horizontal layers. The excavating and loading equipment for overburden and mining operations in these zones is diverse: quarry rope shovels, hydraulic backhoes or their joint work. When they work together in the coal-bearing zone, the rope shovels extracts the interbeds, and the hydraulic backhoes extract the coal seams. However, such technical solutions are not sufficiently substantiated. The fact is that rope shovels and hydraulic backhoes have their advantages and disadvantages in operating.
