摘要
某城市岩土深孔爆破因距民房太近,为最大限度降低爆破振动影响,先后采用导爆管雷管和电子雷管进行延时分段爆破,并进行了现场爆破试验振动监测对比。通过对比分析显示了电子雷管在降低爆破振动与提高爆破效率等方面的优势,实现了预期的应用目的,可供同类工程参考。
Nonel detonator and electronic detonator were used in geotechnical deep-hole delay blasting to minimize the influence of blasting vibration during the project blasting construction in which the blasting center was very near to residence.The results of blasting vibration were contrasted by vibration monitoring test in spot field.The contrast analysis shows that electronic detonators have the advantage in reducing blasting vibration and improving blasting efficiencies.The intended application purpose was realized.The blasting technical experience can be referenced by similar projects.
