Abstract

The finite-element method is used to solve problems about the stressed-strained state and stability of salt-rocks in the vicinity of mine workings of different purposes taking account of features of the deformation and failure of salts in time for the mining-geological and mining-technical conditions of the potassium mines of the Verkhnekamsk deposit of potassium and potassium-magnesium salts in the case of nonhydrostatic initial stressed state of the rock mass. The effect of tectonic stresses on the processes of deformation and failure of rocks in time constituting the interlayer and interchamber pillars is established.
