| Abstract: | This paper responds to the notorious complexity of AE signal from underground coal mines by developing a signal processing method based on wavelet transform,and performing an experimental analysis of field signal.Results show that：wavelet transform boasts an ability to remove the background noise,and decompose complex acoustic emission waveform data into a single feature wave.This study may provide a basis for real time forecasting dynamic disasters. |
