摘要
安徽省淮北矿业(集团)有限责任公司童亭煤矿2019观3孔是一口精准入巷的长期水文观测孔,终孔落点为一靶域半径2m的巷道内。在易斜地层采用定向钻进工艺是保证钻孔精度的有力工具。详细介绍了该孔定向施工的全过程及采取的技术措施,再一次证明了随钻定向在易斜地层施工中的应用价值。
The 2019 Guan3 hole in Tongting Coal Mine of Anhui Huaibei Mining(Group)Co.,Ltd.is a long-term hydrological ob-servation hole that accurately enters the tunnel,with the final hole falling into a tunnel with a target radius of 2m.Directional drilling technology is a powerful tool to ensure drilling accuracy in in-clined formations.This article provides a detailed introduction to the entire process of directional construction of the hole and the technical measures taken,once again proving the application value of directional drilling in construction of easily inclined formations.
