description | Method for protection of mine working includes formation of local zone of unloading with removal of rock pressure round the worked-out space in the place where the working is placed. At least one unloading cavity is separated to sections with different rigidity, at that the rigidity of the central section of the cavity placed directly over or under the working is taken within 0.8-0.01 of the rigidity of the sections that are is cross-section out of the boundaries of the central sections, and rigidity of those sections is takes as 0.8-0.2 of rigidity of the not destroyed massif; at that the dimension of the central section is taken 1.01-6 of the dimension of the projection of the cross-section of the working to the plane of the unloading cavity. |
