The objective of time-frequency analysis on blasting vibration signal is to obtain the distribution of signal energy with both time and frequencies comprehensively and accurately. The RSPWVD quadratic time-frequency analysis method has high accumulation and can suppress the cross-term preferably, but part signal information will loss inevitably in the process, which induce that the details of blasting vibration signal information can’t be got. RSPWVD quadratic time-frequency analysis method and wavelet analysis method are combined to analyze the blasting vibration signal in this paper, the results show that this method increases the precision of time-frequency characteristics of blasting vibration signal and can obtain its detail information. Employing this method can get more intuitive, reasonable, higher-resolution time-frequency characteristics of signal.
