Therefore, local as well as regional monitoring arrays were deployed there in order to investigate the actual seismic activity continually. One of the essential parameters which was observed at the seismic stations situated in-situ was the particle velocity of P- and S-waves. The aim of this paper is to derive some empirical dependences by determining the decrease of seismic wave amplitudes with distance from rockburst foci. Seismic energy, local magnitude, co-ordinates of seismic stations, rockburst foci and positions where damage to workings occurred were employed as additional imput. Moreover, the degree of this damage was tested based on the values of particle velocity and, simultaneously, stress due to the loading of the workings by the stress wave was also calculated.
