摘要
钻井液性能对深井水平巷道围岩地面预注浆工程顺利开展极为重要,根据信湖煤矿地质特点结合水平巷道围岩地面预注浆工程钻孔分段情况,对不同钻孔阶段的钻井液进行了设计。
Drilling fluid performance were very important to the deep level horizontal roadway surface pre-grouting project. In this article,the author introduced geological features of Xinhu Mine,based on the horizontal roadway surface pre-grouting drilling segment situation,the drilling fluid suitable to the different stages was designed.
