区域性岩体微震活动的监测

基于矿井微震与冲击地区产生的原因，提出了岩体微震活动的一整套监测方案。该方案的特点是：①以高速十六位微机为核心，区别于以往的他移监测和压力监测等方法和手段；②具有多种适合于现场的辅助功能；③采用ＳＷ－ＧＢＭ数值源定怄技术进行微震源定位；④求解条件方程时采用奇异值分解最小二乘法；⑤对定位结果给出质量评价；⑥可使用多种震种、震相到时数据。为了验证孩方案的可行性，北京矿冶研究总院研制的８Ｂ１．６ＭＲＡＥ岩体声发射监测定位仪在安庆铜矿进行了实际应用，收到了良好的效果，达到了国内外同类产品的先进水平。

MONITORING OF MICROSEISMIC ACTIVITIES OF REGIONAL ROCK

On the basis of the cause of generating microseismic and rockburst in underground mine,a complete monitoring plan on microseismic activi-ties of rock is put forward.This plan has following characteristics:①A 16bit microcomputer is used as the control kernel, different from traditionalmonitoring of rock displacement and ground control,②Having several auxili-ary functions applicable for practice,③SW-GBM source location principleiS introduced to locate microseismic source;④The singular value is used toresolve least-square in solution of the conditional equatlon;⑤The qualityevaluation is given for the location results;and⑥Data of different kinds ofmicroseismic source and arriyal time can be used.In order to verify the fea-sibility of this plan,8B1.6M RAE Rock Acoustic Emission Monitor and lo-cator developed by BGRIMM is used in Anqing Copper Mine,and satisfied results have been achieved.
