介绍了张集煤矿第二副井及东回风井施工前进行压力注浆的工程设计及技术方案。为提高注浆孔的施工效率和避免场地的干扰,采用了随钻定向钻进技术施工Y形分支孔;鉴于施工区域地质情况的复杂性,在注浆施工过程中,采用多次注浆、控压注浆等方式,较好地解决了裂隙地层串浆和保护井下临近巷道的问题,确保了注浆工程按照要求圆满完成。并对工程设计及施工中的相关问题进行了系统总结和阐述。

The paper introduces the engineering design and technical scheme of pressure grouting before the construction of the second auxiliary shaft and the east ventilation shaft of Zhangji coal mine.Y-shape branch holes were constructed with directional drilling by MWD to improve the construction efficiency of grouting hole and avoid interference from the site.Re-peated grouting and grouting with pressure control were used to solve the mud channeling in fractured formation and protect the roadways nearby.The related issues in the engineering design and the construction are systematically summarized and discussed.
