Abstract
The development of complex-structured coal seams using traditional technologies, including explosive loosening, leads to losses of mineral resources and its significant dilution. Promising equipment for mechanical loosening of complex-structured massifs are surface miners, which provide the necessary depth of selection when extracting minerals and rock layers. The article proposes a technical and technological solution that makes it possible to increase the efficiency of layer-by-layer mining of complex-structured flat coal seams containing strong rock layers of small thickness, by expanding the functionality of a surface miner by equipping it with equipment for preliminary softening of rock layers by cutting intermittent slots in them and impregnating the surface with a solution. active substances.
Keywords
Surface miner, conveyor, coal, dump truck, rock layer, cutting slots, mortar supply, softening.
