Abstract

In order to reveal the mechanism of the interference vibration reduction of the short millisecond blasting of a high-precision detonator, on-site measured single-stage blasting vibration signals were selected to study the time frequency characteristics of the superposed signals in different millisecond intervals using the Matlab program. Comprehensively considering the three elements of the blasting vibration, energy reduction ratio and amplitude ratio were defined based on the HHT energy spectrum to study the influence of the segments, explosive charge ratio and vibration velocity proportion on the vibration reduction effect of the short millisecond blasting. The results show that an extremely big explosive charge ratio nearby should be avoided in the design of the millisecond blasting, and it would be better for a segment with a bigger explosive charge to have a posterior ignition. The research also shows that the energy reduction ratio increases with that of the segments in the same millisecond interval; the energy reduction ratio exhibits little obvious increases with that of the segments after the segments increase to a certain degree; the more similar the vibration characteristics of the two signals are to each other, the more evident the energy reduction effect; the energy reduction ratio of the superposed signals with a posterior vibration velocity proportion is more than the other orders.
