贞丰烂泥沟金矿井下钻探施工工艺探讨

Underground drilling technology for Lannigou Gold Mine of Zhenfeng

摘要:

以贵州锦丰矿业有限公司贞丰烂泥沟金矿井下金刚石钻探工程施工过程为依托，对井下钻探施工中遇到的设备选型、内管输送、孔斜控制、封孔灌注等一系列技术问题，通过调整相应的钻进工艺方法和参数，取得了良好的施工效果。总结和探讨了适合贞丰烂泥沟金矿井下钻探施工的技术工艺，可为类似地层条件下的井下坑道钻探提供借鉴。

Abstract:

With the support of a underground diamond drilling project by Guizhou Jinfeng Mining Co.， Ltd.， a series of technical problems encountered in underground drilling， such as equipment selection， inner pipe transportation， hole deviation control， hole cementation， etc. were addressed through adjustment of drilling processes and parameters， leading to good drilling results. Summarization and discussion are conducted on underground drilling technology suitable for Zhenfeng Lannigou gold mine so as to provide reference for underground drilling under similar formation conditions.
