Abstract:In order to study the explosion tower bare ground vibration attenuation law of blasting, the different loading and mounting height of bare charge explosion vibration test. The results showed that the surface vibration velocity of the suspended exposed explosive in the explosion tower is vertical > Radial > tangential, The influence of the surface vibration velocity on the charge quantity is greater than that of the cartridge mounting height. The vibration frequency in the area near blasting source high frequency attenuation speed is greater than the explosion source far zone low-frequency attenuation speed. The regression analysis of the surface vibration velocity shows that the attenuation coefficient of the bare blasting is obviously less than the empirical value, and there is an explosive reduction factor K"related to the suspended charge, and the value of K" is 0.26-0.56.
