FIELD: physics.
SUBSTANCE: according to the disclosed method of monitoring changes in discontinuities in a rock mass, the probing signal used is a series of separate single rectangular acoustic pulses. Energy of each received pulse in selected frequency intervals is further determined. The ratio is determined and changes in discontinuities in the rock mass exist if the inequality does not hold.
EFFECT: high sensitivity of monitoring change in stress-strain state of a rock mass.
