Justification of anchor support parameters choice for the opening headed in the anisotropic for it's strength rock massif
The researches of the quantitative effect of tension efforts in anchors on the size of discontinuity disturbance zones in the vicinity of a square cross-section single opening, headed in rock massif with strength anisotropy are done. Parameter calculations of anchor support (anchor length, density of their placement around the opening) for rectangular cross-section opening for a number of sides ratio of it's cross-section are done. The results are received within the frames of geomechanical state model of anisotropic for strength rock mass
