Abstract: With respect to the prediction of coal and gas outburst,the re-time monitoring system of multichannel acoustic emission and the relative software system are developed.The location problem of small-scale 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.
