摘要
淮南孔集煤矿在有煤尘爆炸危险及顶板坚硬的采空区内进行中深孔挤压爆破时 ,在国内率先应用煤矿安全导爆索代替多雷管起爆 ,成功地进行了 2 2次爆破 ,解决了生产急需 ,获得了较好的技术经济效果 .并在导爆索起爆性能测定。
Carrying out squeezing explosion in a deep hole in the goaf with a tough roof and coal dust explosion potential,Kongji colliery in Huainan used a safe detonating fuse instead of multi detonators to initiate explosive.This was the first attempt in China.22 explosions were succesfully carried out ,the demands of the production work were met and better economic effects obtained.In addtion,the experiences were gotten in measuring the initiating properies of the detonating fuse,operation technology and how to explode safely in the goaf with coal dust explosion potential.
