FIELD: mining.
SUBSTANCE: method to control engagement of bolting with rock massif includes impact excitation of vibration in bolting and via it in the rock massif with subsequent spectral analysis of a signal of response to an impact against the bolting and a signal of excitation of vibrations in it, and division of the first spectrum by the second spectrum. Using the produced ratio of these spectra, the integrity of bolting engagement with rock massif is estimated.
EFFECT: higher accuracy of control of bolting engagement with rock massif.
