摘要：
The approach to geomechanical modeling of stress fields in rock massif in the vicinity of a circular cross-section mining working, supported by structures based on using rigid fully grouted anchors is proposed. The developed model is implemented in the form of an analytical design method and corresponding computer software. The results of a comparative analysis of the calculated stresses on the contour of the workings cross-section obtained using the proposed approach and on the basis of computer finite element modeling are presented.
