复杂地质条件下冲击地压矿井微震监测系统震源定位精度分析及标校方法

Accuracy Analysis and Calibration Method of Source Location of Microseismic Monitoring System in Rockburst Mine under Complex Geological Conditions

矿井可通过微震监测系统实现对冲击地压发生机理的研究和冲击地压危险的预测预报及防治效果的检测,但为保障定位结果的准确性,在复杂地质条件下,基于爆破定位技术,通过开展震源定位精度分析及标校,确定监测系统合理的波速,实现矿震精准定位,可为矿井冲击地压的防治工作提供可靠信息。

Through the microseismic monitoring system,the mine can realize the research on the mechanism of rockburst,the prediction and prediction of rockburst hazards,and the detection of the prevention and control effects.However,in order to ensure the accuracy of the positioning results,under complex geological conditions,based on the blasting positioning technology,the reasonable wave velocity of the monitoring system can be determined through the analysis and calibration of the focal positioning accuracy,so as to achieve the accurate positioning of the mine earthquake,It can provide reliable information for the prevention and control of mine rockburst.
