Method for working-out bedding-plane steep ore deposits includes separation within height of storey of ore body at its propagation to separate blocks with penetration of development workings with division of each block to two sub-storey with approximately same height with sequential working out those, beginning from the upper one, through penetration at each sub-storey of through workings, drilling massif with deep wells from specially penetrated drill workings and massif breakage of stocks of panel to under-console compensation space formed between of hinging consol of ore massif and broken rock of the previous panel due to difference between the angle of inclination of console of ore massif and angle of friction slope of broken ore after its partial discharge with following discharge and delivery of broken one. Before partial discharge of ore through wells drilled in the upper end of console of the ore massif one feeds pipeline with following supercharging through it of mudding substance that fills cavities of the upper contact section of broken ore and empty rocks placed under the console, after that one makes brake for compacting and strengthening mudded massif with following partial sub-discharge of ore. |
