SPECTRUM CHARACTERISTIC OF BLASTING VIBRATION AND ITS ENGINEERING APPLICATION
Tong Li · Engineering Blasting · 2000
Basic theory of spectrum analysis and Fast Fourier Transform (FFT) algorithm are briefly introduced. On the basis of FFT, a software for the spectrum analysis has been developed. With this software, the spectrums of seismic waves from small scale bench, large scale high bench short delay and chamber blastings are analyzed and the characteristics of these spectrums discussed.
