贵州高瓦斯矿井条件下三步揭煤法防突技术研究与应用

Research and Application of Uncovering Coal Method with Three Outburst Prevention Technique Under Condition of High Gas Mine in Guizhou Province

通过对石门煤与瓦斯防突技术的研究,基本总结出了一套适合贵州高瓦斯条件下的石门安全揭煤技术,为矿井石门揭煤提供了安全基础,对今后各类石门安全揭煤具有借鉴意义。

Through research on the coal and gas outburst prevention technique at cross-cut, a set of safe uncovering coal technology at cross-cut is summed up, which fits the high gas condition in Guizhou Province. The safe foundation is provided for uncovening coal at mine cross-cut. There is reference significance for safe uncovering coal at all kinds of cross-cuts in the future.
