| Abstract: | Based upon the theory of waveform interference,blasting vibration reduction is introduced in theory in this paper.The millisecond delay interval has been considered as the key parameter to reduce the blasting vibration and optimized in the field study.Choosing 15ms as delay interval, the experiments in an open stope have gained favorable ratios of success and vibration reduction.The blasting results show that the optimized blasting scheme and blasting parameters are effective.The valuable reference has been provided for similar engineering of bench millisecond blasting in open stope.2figs.,1tab.,9refs. |
