摘要
Abstract
The coal and gas outburst is one of the worst natural disasters in the coal mining industry. The acoustic emission signals in coal can reflect the forces of the coal body, and we can monitor the acoustic emission signal to achieve the non-contact of coal and gas outburst prediction In this paper, wavelet transform is used in the extraction of coal and gas outburst effectively signal. Using the frequency characteristics of the wavelet transform, acoustic emission signal collected can decompose in a different scale, so that it can filter out the noise very well. The effectiveness of this method has been verified in Matlab simulation software.关键词
