摘　　要：分析了矸石山注浆灭火发生爆炸的原因,利用虹吸原理,研制出防爆注浆灭火管,可达到进浆不进气、排汽不进气的效果,并介绍了其使用方法。The causes of explosion in grouting on spontaneous combustion coal waste plies are analyzed. Based on the siphon principle, a new tube named ＇the oxygen cutting off and fire-fighting grouting tube for spontaneous combustion coal waste pile＇ is eventually developed, which can eliminate the contradiction between water vapour and air, so it can meet the requirement of not entering outside air when grouting and during water vapour emission. And the using method of this tube is also introduced.
