Summary:For structurally complex orebodies in weak zones of enclosing rock mass, a variant of the sublevel stoping technology with cemented paste backfill is proposed. On the ground of the in-situ data, the analytical relations are constructed to determine stability of artificial roof and sidewalls in stopes. It is found that backfill possessing the uniaxial compressive strength of 3 MPa preserves stability in the course of extraction of ore from adjacent stopes and in mining on the lower lying level. The recommendations on backfilling are given.
