摘要(Abstract)：

为研究电子雷管相比于普通塑料导爆管雷管在爆破振动控制方面的优势，在爆破参数以及岩体条件一致的情况下，开展了电子雷管起爆和普通雷管起爆的对比试验研究，结果表明：相同爆心距条件下，电子雷管的峰值质点振动速度比普通雷管的小，电子雷管的爆破振动主频比普通雷管的高，电子雷管爆破振动能量集中分布，主要分布于40～60 Hz和80～200 Hz频带，普通雷管爆破振动能量分布较电子雷管均匀，主要分布于低频频带。电子雷管不仅振动幅值小，且主频及能量占比高的频带均较普通雷管高，对保护建(构)筑物有利。
In order to study the advantages of electronic detonators compared with ordinary plastic detonators in the control of blasting vibration, a comparative test study on the initiation of electronic detonators and ordinary detonators is carried out under the condition of the same blasting parameters and rock mass conditions. The results show that: Under the same detonation core distance, the peak particle vibration velocity of the electronic detonator is smaller than that of the ordinary detonator, and the main frequency of the blasting vibration of the electronic detonator is higher than that of the ordinary detonator. The blasting vibration energy of the electronic detonator is concentrated and distributed mainly in the two frequency bands of 40-60 Hz and 80-200 Hz. The distribution of the blasting vibration energy of the ordinary detonator is more uniform than that of the electronic detonator. Mainly distributed in low frequency band. The electronic detonator not only has small vibration amplitude, but also the frequency band with high main frequency and energy ratio is higher than the ordinary detonator, which is beneficial to the protection of structures.
