METHOD OF UNDERGROUND DEVELOPMENT OF THE INCLINED ORE DEPOSITS Russian patent published in 2018 - IPC E21C41/22 E21F15/00 

Abstract RU 2651727 C1

FIELD: mining.

SUBSTANCE: invention refers to the mining industry and can be used for underground mining of inclined ore deposits of minerals at great depths under conditions of increased rock pressure. Method includes development of the deposit from top to bottom across the strike of the ore body, under the protective concrete layer, which is formed by the inclined splits, longhole stoping of ore during the extraction of the main reserves by means of the inclined chambers, which are developed in the staggered order, shipment of rock mass and filling of the worked out space with the filling material. Protective layer is formed by means of the inclined strips with the calculated angle of production in relation to the air/stowing gate in the horizontal plane.

EFFECT: technical result of the invention is the reduction in the volume of the developing entries, which are carried out on the empty rocks, the reduction in losses of broken ore and its choking.
