摘要
设计并建立了深部开采压力监测预警系统。利用盖革定位法和Matlab软件,对微地震监测网络的布局方案进行了数值模拟和分析。通过对各种方案震源定位精度的比较,优化了布置方案,现场安装了一套完整的微震监测网络。通过数据采集和分析,爆破信号的三维反坐标与实际爆破位置的误差小于10m。因此,该监测预警系统能够满足矿山生产的需要,对预测和预防动态灾害事故具有重要意义。
The monitoring and early warning system of pressure in the deep mining has been designed and established.With the help of Geiger positioning method and Matlab,the layout scheme of microseismic monitoring network has been numerically simulated and analyzed.By comparing the accuracy of source positioning among various schemes,the layout scheme was optimized,and a complete set of microseismic monitoring network was installed on site.Through data acquisition and analysis,the error between the inverted three-dimensional coordinates of blasting signal and the actual blasting position was less than 10 meters.Therefore,this monitoring and early warning system meets the needs of mine production and has a strong significance for predicting and preventing dynamic disasters and accidents.
