Analysis of Blasting Vibration Wave propagation Based on EEMD

Raw data of blasting vibration under the influence of noise and interference events, limited the accuracy of propagation formula. Thus, Analysis of main vibration datas extracting from the EEMD decomposition was done to improve the accuracy of formulas. According to the collected field data of blasting vibration in a mine, linear regression was done to the original datas and main vibration datas to gain each formula, then verified them, the results show that as the correlation coefficient of main vibration is larger, the noise and interference events do little affection to the formula, and its formula is more precisely when short distance propagation.
