Abstract
Based on experimental studies, it was found that taking into account the influence of rock anisotropy allows to improve the location quality by 10 - 20%. It is shown that for processing the results of seismoacoustic monitoring with regard to anisotropy in the controlled area, it is necessary to develop specialized software that implements a velocity model of the wave propagation medium. Approaches to its development and implementation have been formulated. This will improve the location accuracy and, as a result, the quality and reliability of forecast estimates when conducting geomechanical monitoring of a shock hazardous rock mass due to more accurate identification of potentially dangerous seismoacoustic active zones.
