煤层底板突水是矿山建设与生产过程中的主要灾害之一。底板注浆加固技术是目前我国防治底板突水的重要措施和方法。利用定向孔进行煤层底板超前注浆加固,对注浆的层位与注浆材料选取、注浆工艺制定、注浆方法和浆液配置进行了系统研究;针对定向孔的特点对注浆效果检查与评价进行了完善,并通过赵固一矿11151工作面现场进行了验证。试验表明,所采取的注浆工艺技术很好的保障了注浆和钻进施工,注浆加固效果明显,实现了工作面超前区域注浆加固的目的。
煤層底闆突水是礦山建設與生產過程中的主要災害之一。底闆註漿加固技術是目前我國防治底闆突水的重要措施和方法。利用定嚮孔進行煤層底闆超前註漿加固,對註漿的層位與註漿材料選取、註漿工藝製定、註漿方法和漿液配置進行瞭繫統研究;針對定嚮孔的特點對註漿效果檢查與評價進行瞭完善,併通過趙固一礦11151工作麵現場進行瞭驗證。試驗錶明,所採取的註漿工藝技術很好的保障瞭註漿和鑽進施工,註漿加固效果明顯,實現瞭工作麵超前區域註漿加固的目的。

Water inrush from coal floor is one of the main disasters in mine construction and mine production, brings great risks and losses to the coal mine safe production with huge destruction, floor grouting reinforcement technology is an important measure and method for water prevention. Using directional borehole to conduct reinforcement by pre-grouting will be an important development and promotion direction of floor grouting reinforcement technology in the future. According to the characteristics of directional drilling, this paper has systematically studied selection of grouted horizon and grouting materials, grouting technology, evaluation criterion of grouting effect, grouting reinforcement technology is formed. The tests in face 11 151 of Zhaogu mine show that the grouting technology is reliable and advanced to ensure grouting and drilling, the effect of grouting reinforcement is evident, achieves the goal of reinforcement by in-advance regional grouting in working face.
