【摘要】 由于常规爆破震动的监测手段只考虑了振动峰值速度单一因素,不能很好地评价出爆破地震效应的危害程度。利用基于小波包分析技术的时-能密度分析法对爆破震动监测结果进行分析,在综合考虑振速、频率和持续时间三要素的基础上对爆破震动效应做出全面、精确的评价,弥补了常规检测手段的不足,对露天矿爆破生产作业具有一定的指导意义。更多还原

【Abstract】 Since conventional blasting vibration monitoring method only consider the single factor of vibration peak speed,and it could not evaluate the damage degree of blasting seismic effect well.Blasting vibration monitoring results were analysis by time-energy density analysis which based on wavelet packet analysis technology,and comprehensive and precise evaluation was made on blasting vibration effect based on comprehensive consideration of vibration velocity,frequency and lasting time.This method can overcome the shortage of conventional method,and it has certain guiding significant to blasting operation of open-pit mine.更多还原
