摘　　要：针对松软破碎岩层钻孔封孔质量差,瓦斯抽采浓度和流量偏低等问题,提出优化改进的"两堵一注"式带压注浆封孔技术。阐述了该封孔工艺的基本原理和施工流程,于鹤煤某矿1310工作面进行了工业性实验。Under the special geological condition which has soft and broken coal seam, the quality of drilling and hole sealing was poor and gas drainage concentration and flow rate lower. The improved technology of ＂Two Sealing and One Grouting＂, pressurized grouting is raised. The basic principle and construction process of sealing technology are described. Moreover, the commercial test was carried out at 1310 working face in a mine of Hemei group.
