FIELD: mining. SUBSTANCE: method includes vertical division of deposit into levels and sublevels, driving of level and sublevel workings, ore breaking in sublevels, ore drawing, ore delivery, loading and haulage on levels. In so doing, during sublevel ore breaking, ore is partially drawn and loaded and stored ore within the level is drawn by vertical blocks. For this purpose two parallel additional sublevel workings are driven above level block haulageway. Parallel sublevel workings are connected with level haulageway by inclined connections. as each additional sublevel working is driven and vibroactivators are installed in it. Then, periodically with simultaneous engagement of vibroactivators of the block ore is started to be driven in block onto level haulage until full filling of level haulage with subsequent disengagement of vibrators. Ore is transported from level haulage by repeating these operations until full draw of sorted ore in block. Then pillar above level haulageway is worked. EFFECT: higher efficiency. 5 dwg
