【摘要】 减小大孔径中深孔爆破地震波的危害,关键在于控制最高一段起爆药量及产生的爆破振动的能量。本文阐述了在不同的爆区环境下,通过采用孔内分段间隔起爆、孔间分组传爆、排的延时传爆及调整起爆顺序等减振技术措施,可以有效地降低中深孔爆破产生的地震波危害。更多还原

【Abstract】 The key point for reducing the harm of blasting seismic wave resulted from medium deep hole blasting with large diameter lies in the control of maximum amount of initiating explosive as well as its resulting blasting vibration energy.The present paper discussed a effective reduction of intension of seismic wave in medium deep hole blasting in varying blasting environment in terms of its adopted vibration reduction techniques like in-hole stage interval initiating,row-hole grouping propagation,row delay propagation and initiating sequence adjustment.更多还原
