摘要

FIELD: mining industry. SUBSTANCE: ore is broken by hole blasting from drilling levels and loaded out via cut-throughs. Drilling level is worked by cutting roof of haulage way at least up to height of cut-throughs with subsequent backing of lower part of haulage way and filling worked out space in which additionally mined is lower part of room at least up to level of cut-through bed. Lower part of room and haulage way are backfilled to level of cut-throughs of adjacent unmined room. Lower part of room is worked and backfilled after filling worked room with hardening mixes at least up to level of roof of worked room cut-throughs. EFFECT: high efficiency. 1 cl, 2 dwg
