防喷安全装置在石门揭突出煤层中的应用

摘要

This paper introduced the working principle and constitution of blowout control equipment, and the technical approaches which improved the effect of blowout prevention was also presented. Songhe Mine made a series of drilling test research in 1500 rock cross - cut by using blowout control equipment. The results showed that the equipment could safely open up 17 coal seam with gas outburst and good effect was obtained.%介绍了防喷安全装置的原理、结构及提高防喷效果的技术途径。通过在松河矿1500运输石门揭煤抽放钻孔施工中应用防喷安全装置进行试验，实现了安全揭开具有严重突出危险性的17#煤层，取得了较好的效果。
