我矿在采用塑料导爆管进行爆破时,发生过早爆事故.为了确保安全,杜绝类似事故的发生,我们吸取了教训,积极采取了以下技术措施后,经过生产实践证明,收到了较好效果.(一)采用非电起爆材料,对导爆管起爆系统网路进行起爆时,应采取下列措施预防早爆:1.用导爆索连接网路时,导爆索要悬空拉紧、不能与岩帮和底板接触、防止浮石坠落砸响导爆索;
In mine blasting with plastic detonating tube, premature explosion occurred. In order to ensure safety and prevent similar accidents, we learned a lesson, and actively adopted the following technical measures, after production proved to have received better (A) non-explosive material, the detonating tube detonation system network detonation, the following measures should be taken to prevent premature burst: 1. With detonating cable connected to the network, the detonating cord to be dangling tension, not Contact with the rock and the floor to prevent the pumice fall hit the detonating cord;
