英文摘要
In recent years, mine earthquake disasters occurs frequently and has brought great harm. Analysis and Research of mine earthquake weak signals have great significance to reduce casualties and property losses. This paper based on the wavelet transform uses actual mine earthquake signals as the analysis object, and determines wavelet basis function as Sym8 and wavelet decomposition layer as 3 for de-noising processing of actual mine earthquake signals through a lot of MATLAB simulation experiments. At the same time, this paper introduces Birge-Massart threshold acquisition method, and implements effective de-noising of mine earthquake signals combined with the improved threshold function, so that it provides a good condition for the research and prediction of mine earthquake signals.
