摘要
结合北京木城涧煤矿实际情况,研制了一套矿震监测定位系统。根据其多点布台的特点,采取了几种确定矿震震源的方法。以一次较大的矿震为例,采用小波分析滤波过的信号,结合所应用的定位方法,确定了矿震震源位置。此矿震监测定位系统的监测结果与实际矿震十分吻合,定位结果小于规定的误差上限。
Combining practice of Muchengjian Colliery in Beijing, we manufactured a set of rock - burst monitoring and orientation system. Based on the characteristic of multi-station of this system, several methods for seismic source orientation were applied. Taking a larger rock burst as an example, this system applied orientation method and confirmed epicenter on the basis of signal filtered by wavelet analysis. The monitoring result was very similar to actual rock burst and the error of orientation result was minor to prescriptive upper limit.
