Abstract
The article discusses feasibility of frozen wall construction supervision in salt rock mine shafts using seismology techniques. Shallow seismic survey locates wakened areas and intense water flows in rock mass near shafts. Borehole seismics, including crosswell shooting and vertical profiling by the common depth point method, allow estimation of frozen rock thickness. The proposed package of seismology techniques aims to reduce risk of emergencies in construction of mine shafts.
