| Zusammenfassung |
| A new algorithm of seismological information processing of detailed mines catalogue with
use kinematic and dynamical characteristics of deformation waves, which propagate with
different velocities in the rock massif, which is under heavy influence of single
blasts and technological explosions is developed. It is estimated that the waves,
which propagate with the velocities from 10 to 1 m/hour are primary carrier of the
energy in the massif and promote its releasing. Events, which occur in the massive
with these waves with releasing energy less than 104 joules promote to the creep
rebuilding of the massif. Events, which occur in the massive with these waves with
releasing energy more, than 105 joules, can be used as rock burst precursory and
it is recommend taking into account by changing of explosions in the indicated
part of the massif. The whole absence of such events indicates the growing of the
stress massif state in the mine as a whole. The received joined information from
the seismic catalogue is very significant for forecasting of dangerous events in the
rock mines. That algorithm can be used also for analyzing seismic natural events
preparation.
Key words: massif response, slow deformation waves, seismic mine catalogue, analyze of
