4. Conclusions The performed geomechanical analysis of the influence of the deformation history of the salt mass on its destruction made it possible to draw the following main conclusions: 1. Without a retrospective analysis, the geomechanicalestimation of the undermined rock strata destruction is not always adequate to the current situation and can lead to overestimated values of both the current stability of the rock mass and the predicted one, which is unacceptable for safe mining operations. 2. The presented geomechanical estimates are general and methodologically oriented. For specific mining geological and mining-technical conditions, it is advisable to use comparative mathematical modelingmethods to justify a choice of a method with which to analyze the geomechanical situation.
