Abstract
This paper is based on empirical mode decomposition (EMD )of Hilbert-Huang transform (Hilbert-Huang Transformation, HHT) method shall be applied to the blasting vibration signal, first introduced the Hilbert-Huang transform theory and algorithms, then on the seismic wave signal measured as the object, and on the acquisition of signal EMD decomposition are intrinsic mode functions (IMF) components, Then Carries on Hilbert transformation processing to all the intrinsic mode function for Hilbert transform processing, obtained a range of spectrum of summarized information on seismic waves, verified the applicability and effectiveness of the methods of blasting vibration.
