Abstract The paper considers the mechanical behaviour of a salt rock mass around a mine shaft and analyses the causes for the differences in the nature and speed of deformation relative to the analog object. Assuming a significant effect of carnallite inclusions in rock salt on the physical and mechanical properties of the rock, it is proposed to combine carnallite rocks and rock salt zones with inclusions into a unified modelling medium. It is justified by solving model problems based on monitoring data. Adhering to the proposed approaches, the tasks of the “lining – mass” interaction are solved for the types of fastening regulated by regulatory documents. The values of rock pressure in similar mining and geological conditions on a rigid lining are determined. A forecast is given for the stability time of a rigid combined cast-iron-concrete lining and a pliable block lining made of high-performance concrete.
