Within the framework of the geological and geophysical support of water-soluble mineral mining, it is critical in terms of safety to evaluate the induced changeability of rock mass properties. The observed and already active adverse changes dictate the continuous control to be the basis for the specific managerial and engineering decision-making. The modern seismic exploration-based control of impermeable strata in operating salt mines is carried out by the procedure of the common-depth point at two scales. The first scale is the depth exploration down to 700 m and the second scale—down to 100 m, using a set of borehole studies represented by the vertical seismic profiling and by the borehole modification of the common-depth point. A new trend of the shallow seismic exploration is presented—on-line monitoring of elastic properties in rock mass using distributed fiber optic acoustic sensing.
The study was supported by the Russian Foundation for Basic Research and by the Perm Krai, Project No. 20-45-596032.
