Abstract: The article presents research materials and the results of various calculations confirming the validity of the authors' assumption about the feasibility of conducting the stripping and mining operations in the northwestern section of the Elga coal deposit, the largest coal deposit in the Russian Federation, using blastless technology with the KSM -2000R Surface Miners. The strength properties of the surrounding rocks in this section are described, on the basis of which the boundaries of the technological zones available for blastless mining of coal and stripping operations using surface miners. Uneven distribution of various rock types across the area and the depth of the rock mass is emphasized. It is emphasized that transition to the blastless mining methods will contribute to enhancing the profitability of the mining company, protecting the environment, and addressing a number of environmental issues in the region, in particular, by eliminating large-scale blasting, thereby reducing the level of induced seismicity, as well as significantly cutting down the emissions of toxic coal and rock dust, gases that pollute the air and land surface, thereby reducing the psychological stress and morbidity among the region's population

Keywords: coal deposit, surrounding rocks, surface miner, blastless technology, rock strength, mining and geological information systems, mapping
