摘　　要：某近城镇露天矿山生产爆破产生的爆破振动对周边城镇区域影响较大。为控制爆破振动危害,引入数码电子雷管,并进行降振应用研究。通过比较数码电子雷管不同延期时间下爆破振动的大小,确定了适宜于降振目的的延期时间设置方案。结果表明,数码电子雷管延期时间为28 ms时降振效果最佳,平均降振幅度达31.65%。通过实践证明,在适宜的延期时间下,数码电子雷管具有较好的降振效果,为同类工程提供借鉴。The production blasting vibration of an open-pit mine near a town has a greater impact on the surrounding towns.In order to control the blasting vibration hazards,digital electronic detonators were introduced,and vibration reduction application research was carried out.By comparing the magnitude of the blasting vibration of the digital electronic detonator with different delay times,the delay time setting scheme suitable for the purpose of reducing vibration is determined.The results show that the digital elec⁃tronic detonator has the best vibration reduction effect when the delay time is 28 ms,and the average am⁃plitude reduction is 31.65%.Practice has proved that the digital electronic detonator has a good vibration re⁃duction effect under a suitable delay time,which can provide a reference for similar projects.
