Abstract

The methods of determining the parameters of anisotropy of rocks, containing mine workings, the nature of the deformation of rocks in the contour zone during elastic-plastic deformation are shown. The issues of determining the shapes and sizes of inelastic deformation zones depending on the physical and mechanical properties of rocks, the depth of mine workings and the size of the cross-sectional section are considered.
