Abstract: This paper introduced micro-seismic monitoring system’s structure,principle,layout,orientation and post-processing of monitoring information.Based on micro-seismic monitoring,this paper analyzed possible rock-burst danger induced by residual stress of gob or tectonic stress of fault.Results were showed as follows.When micro-seismic activity was continuous unbalanced active and showed increased trend,rock-burst danger was large.When micro-seismic activity was continuous recessional but underground pressure behavior was exceptional strong,rock-burst danger was also large.Micro-seismic monitoring system would play important role on the forecast of coal and rock dynamic disaster in deep mine.These results might provide reference to rock-burst monitoring and preventing.
