Assessment of compliance of mining and backfill operations design parameters at Verkhnekamsk potash mines with mining and geological conditions from the perspective of geodynamic safety of the subsurface and the earth's surface

The methodology and results of the numerical estimation of the stress-strain state (SSS) of the undermined rock mass under the design parameters of mining operations at the First Berezniki potash mine are considered. The geological structure of the rock mass and the propensity of salt rocks to creep and relaxation are taken into account.
