At the moment (3), there were two zones of subvertical fracturing that were most extended in height. The first one was formed at the boundary of block 51 and block 49 and was confined to anomaly I. Here, the WS layers up to the OSR soil were disturbed. The second zone was formed at the boundary part of the two-layer mining at the eastern boundary of block 183 and was confined to the anomaly boundary III. The area of shear fractures covered the WS from the stratum B roof to the soil of the OSR. The stability of the WS is provided. 4. Conclusion The existing experience of using seismic geomechanical studies in the mine fields of the Verkhnekamskoye potash salt deposit allows the geomechanical situation in areas with a complex geological structure to be monitored, controlling the formation of zones of man-induced disturb-ances, estimating the danger of their development and, if necessary, taking additional measures to protect the WS.
