Seismic-Geomechanical Control of Water-Impervious Strata in Potassium Mines

摘要

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