Abstract:
In order to improve the blasting vibration and boost the efficiency of blasting energy, this paper mainly focuses on the delay time control research through transmission law. We performed an experiment with a delayed-detonation scheme in different period, which selects common detonator and Orica high precision detonator. The measured vibration of the earthquake wave is based on seismic wave function optimization theory foundation. The measured data and wavy figure were acquired through it, then we found out the variation characteristics of the rules of earthquake wave propagation, peak velocity, domain frequency, band energy and the total energy in different delayed period. At the same time, according to the characteristics to find velocity map which Synthesized by triaxialvibration wave and displacement map which assembled by speed Calculus correspond to the maximum in same time. On the basis of peak velocity-vibration displacement distribution characteristics, fitting method for Gaussian multi-peak is applied for measured vibration wave, to give the band energy maximize time points about t=60 ms, blasting vibration around the minimum time for t=25 ms. © 2016, Editorial Board of EXPLOSION AND SHOCK WAVES.
