摘要：

光纤微震监测技术通过观测分析生产活动中产生的微小振动事件,对其进行监测预警,具有无源、可靠性高等优点。传感器垂直安装在巷道帮部锚杆上,监测分站安装在硐室内,传感器与监测分站通过敷设的光缆形成监测网络。采用单纯形法进行震源定位,此方法在定位计算过程中不会出现发散问题,稳定性高,在求解过程中不需要求解偏导和逆矩阵,降低了运算量,提高了运算效率,每只传感器可以根据实际情况采用不同波速进行计算,更加符合实际情况。光纤微震监测系统安装于山西五阳煤矿,进行了初步的监测应用,并对监测结果进行了分析,结果证明该系统能够监测矿山活动,发挥预警功能,对安全生产起到了积极作用。

Abstract:

Optical fiber microseismic monitoring technology is used to monitor and alert the microvibration events generated during production activities through observation and analysis with passivity and high reliability. Herein, the sensors are vertically installed on the side bolts along the roadway, and the monitoring substation is installed in the chamber. The sensors and the monitoring substation constitute a monitoring network through the laid optical cables. Besides, the simplex method is used to locate the seismic source. This method is free from divergence problems in the location calculation and is highly stable. Moreover, in this method, the solution of the partial derivative and inverse matrix is not required, which reduces the calculation amount and improves the calculation efficiency. Additionally, each sensor can use different wave velocities during the calculation based on the actual situation. The optical fiber microseismic monitoring system was installed in Shanxi Wuyang Coal Mine for preliminary monitoring and application, and the monitoring results were analyzed. The results show that the system can monitor mine activities and warn early, thereby playing a positive role in safe production.

Key words: optical fiber acceleration sensor, microseismic monitoring, simplex method, monitoring and early warning
