Abstract
Based on studies of the direction of propagation of the field of elastic vibrations in the mines of the Verkhnekamskoye salt Deposit, employees of the research laboratory of Geophysics of JSC VNII Galurgii, with the support of Uralkali, developed a method for mine seismic exploration on transverse waves with reflection separation (TWRS). Field works in this method are performed by the method of reflected waves according to the method of a common middle point using horizontally oriented seismic receivers installed in the wall of the workings. Excitation of vibrations occurs by horizontal blows to the wall where the sensors are installed, along two lines of source points, above and below the receiving line. Further research has shown that the developed method allows obtaining objective data on the structure of the salt column. However, the materials obtained in this case have a significant difference from the results obtained by other methods. In this regard, there was a need to develop a basic graph for processing data obtained by the TWRS method, which is what this work is devoted to.
