FIELD: mining.
SUBSTANCE: invention relates to mining industry, namely to development of shallow and inclined high coal seams with the use of hydromechanization. Method for the development of shallow and inclined high coal seams includes block preparation and a cleaning hydromonitor excavation of coal seams, in this case, a layer is softened within the working column before the cleaning excavation by softening the soil in accordance with the scheme of a chamber system for the development of unloading excavations in the direction from the excavating heading up to the collapsed space with the temporary formation of a strip of ribbon pillars at a given yield, the width of which is determined by empirical dependence, which ensures the softening of the coal bed and allows the use of a hydromonitor excavation in the swirl with fan-shaped shavings.
EFFECT: method for mine sloping and inclined high coal beds is offered.
