在雷管起爆错相减震原理的基础上,进行毫秒延期雷管和电子雷管起爆试验。通过对远近场地爆破引起的振动监测,在距爆源>50m的位置,其衰减规律符合萨道夫斯基公式。电子雷管的错相减震效果明显,其震动明显低于普通毫秒延期雷管,且在爆区中心30m以外的振速不足2?5cm/s,可有效避免爆破地震造成的危害。

The detonating experiment about millisecond delay detonator and electron-delay detonator was carried out on the basis of the principle of shock absorption by phase dislocation. Through the blasting vibration monitoring about the near and far field, the attenuation rule of blasting shock accords with the Sadov’s formula when the length is more than 50m from the explosion center. The decrease of shake is obvious by using electron-delay detonator. It is significantly lower than the common millisecond delay detonator and the vibration velocity is less than 2?5cm/s 30 meters outside of the explosion center, which can effectively avoid the damage of blasting earthquake.
