Abstract
The article describes a safety control system for water-soluble mineral mining in complicated ground conditions. The system is based on geomechanical interpretation of surface and underground seismic monitoring. Mathematical modeling of water-impervious strata takes into account the whole set of mine-technical and geological factors determined from the seismic observations. It is shown that seismic-geomechanical monitoring allows stress state control in waterproof strata, which ensures prompt decision-making on extra protection and minimizes accident risks.
