Abstract (in english)
   An algorithm for localiton the rockburst events from recods obtained of a three-component surface station in the Kladno-Mayrau coal mine is proposed. The focal distances of mine tremors are calculated on the basis of preliminary knon values of P- and S- velocities. The time differences ts - tp are determined betwween maximum amplitudes instead of the onsets. The azimuth angles are determined from polarization diagrams for double integrated particle motion velocity. Reliability of this approach was verified on the basis of "known" location, obtained from the formerly complete mine seismic network by standard method. The result could be useful for automated evaluating seismicity parameters of known active zones with known seismic models and types of seismic events
