| Abstract: | A seismic sensing method has been tested in the conditions of a surfaced mine. As a result, dynamic strains of rocks exposed to different strength blasting have been measured with seismic equipment and the prevailing vibro-frequency range has been determined for blasting in rocks and in the dump area with the difference specified. The authors have proposed an approach to choosing parameters of a borehole longitudinal multichannel deformometer intended for deep rock displacement and deformation control. |
