Abstract

Brief descriptions of methods, equipment and results obtained by means of the high-frequency method of seismic radiation in research into the states of stress and strain in the vicinity of mine openings in time. Based on seismic measurement of individual boreholes, the relative location of disturbed areas in the vicinity of mine openings is defined and qualitatively deviating faulted zonds resulting from varying states of stress within a rock mass both in space and time. The results obtained by measurements of varying velocities in the propagation of elastic waves are analysed in order to indicate variations in extent and shape of zones where stresses are either relieved or concentrated including variations of stability zone boundaries of initial states of stress within a rock mass in a selected cross section of mine opening.
