摘要
针对煤与瓦斯突出的预测预报问题，开发了多道声发射实时监测系统及有关的软件系统；采用机械噪声抑制和多道相关处理技术、波形自动识别技术及动态数据统计分析中最小标准偏差理论等。
With respect to the prediction of coal and gas outburst,the realtime monitoring system of multichannel acoustic emission and the relative software system are developed.The location problem of smallscale acoustic emission source under the underground heterogeneous media is solved successfully by using the mechanical noise suppression and multichannel correlation processing,wave form automatic recognition and minimum standard deviation theory in the statistical analysis of dynamic data.
