In order to better understand the regularities of rockburst occurrence,Dongguashan Copper Mine has installed an ISSI seismic monitoring system, which can make a real-time monitoring of rock mass respond to mining. This paper briefly described the layout of the monitoring system in Dongguashan Copper Mine,then analyzed how to process various kinds of event waveforms. By contrasting the different locations resulting from the automatic processing and the artificial processing, it is confirmed that the accuracy of an event location has been improved greatly by the artificial processing, which will make the calculation of seismic source parameters even more accurate. Based on the corresponding relations between waveforms recorded and mining practice, the event waveforms are assorted, which can identify events quickly. According to the analysis results of a detecting blast and an identified seismic event,the waveform analysis method put forward in this paper is validated. It will establish a sound basis for subsequent analysis of the stress or strain status,delineation of hazardous areas of rock mass and adoption of reasonable measures.
