Wavelet Analysis of Rock-burst Signal Based on the Matlab

Mine seismic monitoring has been a kind of effective method for preventing rock-burst.Mainly through the arrangement of the mining area rock-burst monitoring system,it recorded the mine earthquake seismic wave,then processed and analyzed the seismic wave form,thus determined location and energy size of the rock-burst seismic source.Based on Matlab software,and through wavelet analysis of rock-burst signal,according to continuous wavelet transform to detect mutant site of the signals,thus it able to determine the original time of the rock-burst signal P-wave.Finally,it can effectively get rid of the noise from rock-burst signal through wavelet denoising.
