Abstract
For improvement of a technique of the forecast of danger of mountain blow the analysis of results of laboratory researches of a vibration signal and acoustic issue at axial compression of samples of the KMA ferruterous quartzites is made. Noted local decrease of intensity of a vibration signal at monotonous increase in tension in rock is explained by manifestation of residual deformation of rocks, and the subsequent its increase - manifestation of elastic stratification of rocks before their destruction. The schedules of intensity of a vibration signal calculated according to laboratory data significantly differ from accepted standard, but correspond received at underground researches of a massif, are well differentiated in a form - therefore can be used for a quantitative assessment of danger of mountain blow, as a percentage of strength of the massif
