| Abstract: |
| In allusion to the current situation of ground pressure disaster (rock burst, etc) appeared frequently during the process of deep mining in Lingnan gold mine, we established a microseismic monitoring system to realize the continuous monitoring for rock mass and the real-time prediction for rock burst. Based on the sensor layout principles and the conditions of mine, we made the array analysis of microseismic monitoring system, calculated the location accuracy of seismic event and the sensitivity of system, and got the optimal sensor placement plan. The fixed-point blasts were used for wave velocity correction. The location results show that the average positioning error of microseismic monitoring system is 5.7 m, which can meet the needs of the mine. Based on the monitoring data recorded in Lingnan gold mine microseismic monitoring system, we research the space-time evolution rule of the microseismic activity and location of private mining, and achieve the preliminary results. |
