FIELD: seismic acoustic research of mine workings and boreholes. SUBSTANCE: in two points of studied interval of borehole synchronous measurements of longitudinal and transversal oscillations parameters are carried out. According to differences of phases, time periods, amplitudes, frequency spectrums speeds of the oscillation s propagation, state and value of seismic momentum and also linear sizes of cracks or angular frequencies of spectrum. Using ratio of the parameters rocks stressed states are determined. EFFECT: increased accuracy of measurements.
