Abstract:
With the increase of mining depth, pre-mining rock stresses increase dramatically, which leads to the rise of the frequency of rock burst occurrence and the drop of mine safety. Base on the micro-seismic monitoring technology, the setting-up of the rockburst control system in deep level mining can improve the safety of mines with rockburst proneness or rockburst hazard. The control system discussed in this paper includes: establishing a micro-seismic monitoring network, processing the micro-seismic event waveforms, digitizing the micro-seismic event source parameters, analyzing the change rules and models of the source parameters during mining, identifying hazard areas and the hazardous magnitude, adjusting and adopting an appropriate mining strategy accordingly.
