The theoretical description of the phenomenon of damping of elastic waves in laminated environment is executed. The mathematical modeling of changes of the intense-deformed condition of a rock mass near to exposure is carried out. The connection between factor of damping of elastic waves in laminated environment and frequency of acoustic signals is established. Product Description popup.authors popup.nrat_date 2020-04-02 Close
