摘要(Abstract):
福建明溪兰圈采石场距村庄较近,为了最大限度地降低采石爆破振动对周围村庄的影响,采用电子雷管进行毫秒延时爆破,降振效果明显;并对电子雷管爆破振动进行监测,针对爆破振动信号具有非平稳随机的特性,利用小波变换分析技术,将爆破振动信号分解在不同的频率带上,获得爆破振动信号的细节信息,较好地反映了爆破振动信号的非平稳特性。
In order to maximum reduce the effect of the blasting vibration on the villages which are close to Fujian Mingxi Lanquan quarry,the electronic detonators were used in the millisecond delay blasting.The effect of vibration reduction was clear,and the blasting vibration was monitored.According to the non-stationary random feature of the blasting vibration signals,the wavelet transform to decompose the signals was used in different frequency band.The result showed the details of the signals and reflected the non-stationarity characteristics of the blasting vibration signals better.
