囊袋式封孔技术在探水钻孔中应用

Study on Technical Measures for Improving Safety of Drift Water Exploration and Drainage Construction

为了提高探水钻孔封孔质量,保证掘进巷道探放水施工安全,避免因探水钻孔封孔不合格,造成放水过程中出现窜孔现象,导致透水事故发生,潞安集团漳村煤地测科矿通过技术研究,对传统探水钻孔封孔工艺进行优化,提出了囊袋式封孔技术,并在2301风巷探放水施工过程中进行应用,取得了显著应用成效。

In order to improve the sealing quality of water exploration boreholes, ensure the safety of water exploration and drainage construction in tunnels, avoid the phenomenon of channeling in the process of water drainage due to the unqualified sealing of water exploration boreholes, and lead to the occurrence of water leakage accidents, Zhangcun Coal Geological Survey Mine of Luan Group optimized the traditional sealing technology of water exploration boreholes through technical research, put forward the bag sealing technology, and explored water drainage in 2301 wind tunnel. The application in the construction process has achieved remarkable results.
