Introduction Characteristics of the geological structure of the Verkhnekamskoye potash salt deposit (VPSD) entail considerable safety risks for the mining operations and reduce the mining efficiency. Thus, the problem of protecting the potash mines from flooding can be solved by an adequate con-sideration of the structural characteristics of salt strata in geomechanical calculations. To solve such problems, we suggest using the developed method of the seismic-geomechanical monitoring of the salt mass state, which has already been implemented in the mine fields of the Verkhnekamskoye deposit. One of the main elements of the developed method is the mathematical modelling of geomechanical processes, whose parametric support is based on results of the surveying observations of the surface displacement and data from the seismic measurements.
