Abstract: Undestroyed deep holes will enhance massif breaking indices due to increased quality of muck crushing and corresponding decrease of oversize yield. Increased quality of rock massif breaking will enable muck ore indices and broken rich ore extraction from stopes. Thus, considerable rock pressure growth at great depths places special requirements on stability of exposed stopes as well as stability of crown exposures of stopes and compensating rooms when designing stopes. Due to it, when mining rich iron ores by sublevel caving systems, wider application of vertical and inclined compensating rooms is recommended for Krivbass underground mines.
