Opencast mining of coal deposits is a priority in Russia, while providing coal to the domestic and foreign markets. Despite reasonable concerns about air pollution and greenhouse gas emissions, coal use will continue to be significant in the future. Consequently, it is necessary to introduce less polluting and more efficient technologies in the industry in the coming decades. Coal deposits are being developed by the open method with a limited deposit length. An indicator for estimating volumes is proposed -the ratio of sediment fraction in a quarry. The dependence of the sediment fraction in the quarry on the pit depth, thickness and angle of incidence of the formation of coal seams (with an oblique and steep fall) is established. Recommendations on the use of land-saving dumping for the open-cast mining of coal deposits have been developed. The structure of complex mechanization on dumping is proposed depending on the properties of rocks (soft or bedrock) and types of transport.
