FIELD: mining, particularly to develop underground inclined ore deposits having mean thickness.
SUBSTANCE: method involves driving block rise workings, main slushier drifts in ledge wall; forming additional slushier drifts in ore body; connecting main and additional slushier drifts with interpanel raise mines; cutting interpanel raise mines in breakage chambers by breaking operation; slushier ore from breakage chambers to ore passes via additional slushier drifts; cutting ore passes in outfall funnels and excavating ore massif over main slushier drifts with the use of additional slushier drifts for drill around operation; communicating next interpanel rise mine with breakage chamber; cutting ore massif part over linkage heading along with breakage chamber cutting along with ore delivery in breakage chamber by blasting operation.
EFFECT: decreased losses along with increased operational safety.
