Abstract :
We acquired blasting vibration signal with TC-4850 blasting vibration instrument in a certain blasting project. Then the signal was analyzed in time-frequency analysis scope with db11 wavelet basis. It can be seen that over 80% of the power in blasting vibration original wave whose frequency ranges below 300Hz. The result is a theoretical foundation to prevent blasting vibration destruction, and can be referent to establish blasting vibration safety criterion.
