Abstract：In order to ascertain time，position and magnitude of rockburst occurrence，considering the actual situation of coal mine，rockburst monitoring and orientation system is developed. This system can monitor destructive rockburst in kilometer dimension of mining area and has the independent intellectual property right in China. Four substations composed of three-component acceleration sensors are laid in the mining area floor，collecting vibration wave signal. In order to guarantee the time accuracy of rockburst data of four substations，GPS network time service can be achieved. Based on the characteristics analysis of the vibration wave frequency and amplitude，rockburst wave is identified automatically；and vibration signals of shooting and so on are eliminated. The rockburst signals of every substation are transmitted to the center measuring and controlling computer by the network. The center measuring and controlling computer manages every substation by remote control，monitoring working condition of every substation. At the same time，by the center measuring and controlling computer，the data is analyzed and managed；the time of rockburst occurrence is calculated；and the rockburst magnitude is computed by duration of rockburst wave. Three methods for computing the location of rockburst are adopted. This system provides a basis for prompt and accurate disaster relief and decrease of loss in the mine. At the same time，the statistic analysis of the time，frequency，location and magnitude of rockburst occurrence is carried out every day with the system；and the future trend of rockburst occurrence can be forecasted. The operation of this system in a year shows that the monitoring results are fully identical with the actual rockburst；and the orientation results are smaller than the error of upper limit.
