Abstract: One of the important problems in underground mining of mineral deposits is an overall decrease in the efficiency and safety indicators of mining systems due to the damage caused by ore overcrushing when mining the mineral reserves. With regard to the considered problem of ore overcrushing and its negative consequences, a topical issue is the consideration of technological methods for reducing complex damage based on automation of geotechnological processes and the targeted formation of mining conditions that allow for an efficient unlocking of the potential offered by the new technological mode. Reducing direct damage when mining metal ores is primarily associated with a targeted change in the mining conditions that would make it possible to efficiently use the remotely controlled mobile equipment not only for mining the main ore reserves, but also for removing available ore fines from the stope area. The main transformable elements of the stope area are the floor and the roof. The degree of the floor roughness and its angle of inclination have the greatest impact on the efficiency of removing the ore fines, while the condition of the roof determines the possibility to use mobile equipment in the stope area. The study revealed a dependence of the metal loss on the thickness of the ore body and the height of the lost ore layer using the case of mining impregnated copper-nickel ores. The types of damage caused by ore overcrushing are systematized. The paper presents technological solutions to reduce the damage of ore overcrushing using remotely controlled equipment as well as the potential effects of their implementation.
