Abstract：Blasting with electronic detonator can be used to make the main band frequency of energy distribution move towards high-frequency and the distribution trend will be more homogenized. EEMD (a collection of empirical mode decomposition)can be used to analyze the main band frequency of blasting vibration energy distribution, which illustrate that blasting main frequency band of vibration energy appeared in 15 Hz-45 Hz. Blasting vibration energy distributes in the frequency band below 10 Hz less than 4.5 % of the total energy of the following, which effectively avoide the low-frequency vibration damage of buildings.Use of blasting vibration energy distribution and energy distribution with frequency proportional to the building safety analysis are effective attempt.
