多年来,爆破行业认为8ms的延迟间隔时间是各段药包之间独立起爆所需的最小延迟时间。但是,对几次露天矿爆破的地震记录所作的计算机分析表明,为使各段起爆的爆破振动相互隔离,8ms的最小延迟间隔时间往往是不够的。有时,短的延迟间隔时间和低频振动的组合可能会导致爆破振动振幅的增大。对单个炮孔爆破的地震记录分析可用于预测增强或减少爆破振动效应的延迟间隔时间。 Over the years, the blasting industry has argued that the delay interval of 8 ms is the minimum delay required for independent initiation of the kits between segments. However, a computer analysis of the seismographic records of several open pit explosions shows that a minimum delay interval of 8 ms is often not sufficient to isolate the detonation vibrations of each section. Sometimes a combination of short delay times and low-frequency vibrations can result in an increase in the amplitude of the blasting vibration. Seismic recording analysis of a single blasthole blast can be used to predict the delay interval to enhance or reduce blasting vibration effects.
