Abstract
The paper considers three basic schemes of roof failure above the face bottom of long-wall during mining operations covering the whole diversity of mechanisms of support-roof interaction. The model of interaction between the powered support and heavy roof is given as well as the calculated scheme for the determination of necessary rated resistance of roof.
