Abstract
Summary
With the participation of the authors, a method of mine seismic exploration on transverse waves with reflection separation was previously developed. It has shown high efficiency in studies of the halogen formation of the Verkhnekamsk salt Deposit. During the development of this method, experimental work was performed, which allowed us to establish that reflected longitudinal waves are not recorded on seismic records, although direct longitudinal waves are recorded quite successfully. In this case, the transverse waves are recorded as direct and reflected. This situation is unexpected, and difficult to explain, because, as is known, the vast majority of seismic surveys, both land-based and mine, are performed using just longitudinal waves. For theoretical justification of the conclusions obtained on the basis of practical research, it was decided to study the process of wave propagation in the salt array using mathematical modeling methods. The numerical solution was obtained using the ANSYS package. This package allows to solve various classes of problems in continuum mechanics, including modeling the processes of elastic wave propagation in different media, which makes it possible to theoretically confirm the results obtained in the course of practical research.
