摘要:
采用电子雷管与导爆管雷管在紫金山金铜矿进行工程爆破实验，通过对比分析大块率、铲装效率和根底数量等数据，证明了在露天开采中应用电子雷管可以降低大块率、提高铲装效率、改善爆破效果；通过监测电子雷管爆破振动，分析了延期时间对爆破振动的影响，发现延期时间不仅影响爆破振动峰值速度，而且决定爆破振动频率的大小和频率分布规律，并给出了实验条件下的较优爆破参数为孔间延期20 ms，排间延期73 ms。
Abstract:
Engineering blasting experiments were carried out by using the electronic detonator and detonator with shock-conducting tube in Zijinshan gold copper mine. The contrast analysis of large boulder rate, shovel efficiency and the number of bottom proved that in the surface mining the application of electronic detonator could reduce the rate of large boulder, increase the shovel efficiency and improve the blasting effect. Via monitoring the electronic detonator blasting vibration, the effect of delay time was analyzed. The delay time was found out not only to affect peak speed of the blasting vibration, but also determine the size of the blasting vibration frequency and frequency distribution. And the optimal blasting parameters of delay time between holes 20 ms and between rows 73 ms were also given in the experimental condition.
