由北京矿冶研究总院和凡口铅锌矿共同完成的“大直径深孔采矿无外露雷管脚线起爆系统”试验成功。它具有较高的灵活性、操作简便、可靠性高等特点,在我国尚属首次,尤其在阶段深孔台阶崩矿采矿法中的应用在国外也未见文献报道,这项技术的试验成功,对于更新大孔爆破器
The successful trial of “Large-diameter Deep-hole Mining Non-Exhaust Detonated Foot-line Initiation System” jointly completed by Beijing Mining and Metallurgical Research Institute and Fankou lead-zinc mine. It has the characteristics of high flexibility, simple operation and high reliability, which is the first time in our country. Especially in the application of deep-hole bench collapse mining method in the stage, it has not been reported in foreign countries. The experiment of this technique is successful, For updating big hole blasting machine
