An analysis of field studies for mining of deep shifts frames is presented in this article. A spatial model is developed, the results of mathematical modeling are presented, they are based on finite element method of nonlinear deformed ore body, which includes the system of wide workings on the 6-th block of –370 m horizon of the Yakovlevsky mine, which consistently pass and laid hardening mixture.
The article presents the consistent patterns of the changes in stress-strain state of the massive by the minings of the first stage of protective overlapping in the Yakovlevsky deposit. The change of the stress-strain condition of the rock massive, which is weaked by the mining was determined by the method of finite elements. The stresses distribution in the massive, the displacement of the contour of the minings, the size of conditional zones of non-linear deformations has been obtained. For stoping passes at the first stage the cutting with combine and application of fastening with the anchors has been suggested.
