| Abstract: | 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. |
