大掺量粉煤灰浆液固化密闭充填封堵漏风技术研究

Study of Large Amount of Fly Ash Slurry Curing Sealed Filling Plugging Leakage Technology

开发了大掺量粉煤灰浆液密闭固化充填技术,并将该项技术在云冈煤矿8617工作面顺槽进行了成功运用,对工作面5条顺槽进行粉煤灰固化充填,封闭漏风通道后有效防止了煤自然发火,保证了工作面安全生产。粉煤灰浆液固化密闭充填封堵效果好,值得在今后防灭火工作中大力推广。

A high volume fly ash slurry sealed curing filling technology was developed,and the technology were successfully used at 8617 working face of Yungang mine,for face five crossheading be cured fly ash filling,closing leakage after the channel effectively preventing coal spontaneous combustion,ensuring the safe production face. Fly ash slurry sealing and filling sealed curing effect,worth in the future to promote fire prevention and control work.
