Abstract
Summary
The paper presents the results of mine seismic surveys of safety pillars at the Upper-Kama potash deposit. The orientation of vibration source at generation of waves into wall of mine working is considered. It is established that the direction of propagation of elastic waves of the P-type, in contrast to S-type waves, is characterized by a certain selectivity and corresponds to the direction of emission. The possibility of high-quality separation of P and S waves in digital data processing is shown. In case of lateral half-space transmission on reflected waves, structural and lithological features of the rock mass are distinguished due to joint analysis of seismic sections and their velocity characteristics.
