Zusammenfassung:	FIELD: mining industry. ^ SUBSTANCE: method includes dividing ore body on levels, and levels on blocks, driving ventilation and passing mines and ore chutes, mounting elastic shields in blocks, extraction of ore in blocks in horizontal layers with forming of trench and leaving support blocks along trench boards for support of elastic shields, transportation of ore under elastic shields, following extraction of ore from support blocks with concurrent placement of elastic shields and its delivery. Ventilation-pass mines and ore chutes pass along ends of blocks in enveloping empty rocks, extraction of ore in block during forming of trench is performed by combine, and from support blocks with concurrent placement of elastic shields - by mechanized complex. Between trench soil and elastic shield a ventilation channel is formed, which is connected to ventilation-pass mines. Ore is transported by conveyor, mounted in trench. ^ EFFECT: higher effectiveness, higher safety. ^ 9 dwg
