FIELD: mining, particularly, underground mining of steeply dipping deposits. SUBSTANCE: method includes sinking of vertical main hoisting shaft from ground surface beyond zone of shift of enclosing rocks, and blind shafts for opening-up of deep horizons located within shaft bottom of overlying hoisting shafts with transfer of ore lifted by underlying blind shafts directly into collecting bin and skips of overlying hoisting shaft. Due to such solution, loading of ore lifted by blind shafts into mine cars, its transportation to shaft bottom and its unloading into collecting bin of next hoisting shaft are obviated. EFFECT: considerable reduction of expenditures for lifting of mined mineral to surface. 1 dwg
