Abstract:	Krivbass rich iron ores are mined by stoping at the depths of 1200-1450 m, preliminary development reaching 1600 m. Increased rock pressure decreases stability of mine workings, in particular stopes and compensating rooms, affecting stability of the most vulnerable element - exposed crowns of underground workings [1-8]. Due to this, the problem of stability of exposed stope and compensatory room crowns gains considerable importance when designing stopes at great depths.
