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。
Based on the causes of microseismic and impact areas in mines, a set of monitoring program of microseismic activity of rock mass is proposed. The program is characterized by: ① high-speed 16-bit microcomputer as the core, different from the previous he moved monitoring and pressure monitoring methods and means; ② has a variety of auxiliary functions for the scene; ③ SW-GBM source怄 technology microseism source localization; ④ solving the equation of the equation using singular value decomposition least squares method; ⑤ positioning the results given the quality evaluation; ⑥ can use a variety of earthquake species, seismic phase to time data. In order to verify the feasibility of children program, Beijing Institute of Mining and Metallurgy developed 8B1.6MRAE rock sound emission monitoring locator in Anqing Copper Mine has been the practical application, has received good results, reached the advanced level of similar products at home and abroad .
