A stress-strain state of the rock mass around a working under localization of shear strain along the joint fissures is considered. The shear lines are modeled by cuts with conditions on them providing the possibility of appearing of discontinuities in shear displacements. An elastic material stress-strain behavior outside the shear bands is proposed. A finite element method is used for numerical modeling this problem. The contour lines of maximum shear stresses for different location of shear lines in the domain are constructed.
