Abstract: In order to solve the problems of current monitoring system of rock burst such as single monitoring signal and non real-time comparing of different signals, a multi-signal monitoring software of characteristic signals of electromagnetic radiation, micro-vibration and audio emission of coal rock was developed based on VC++6.0. The structure and function of the software and the design of each function model were introduced. The software has functions such as multi-channel real-time display, data storage, historical data queries, trend analysis, statistics and so on. Through analyzing multi-signal of characteristics of coal rock, the software can forecast dynamic disasters of coal rock more effectively.
