定向长钻孔在母杜柴登煤矿顶板探放水中的应用

Application of Directional Drilling Technology for Water Exploring and Discharging in Roof of Muduchaideng Coalmine

摘要:

水灾是威胁煤矿井下安全生产的三大危害之一，施工探放水钻孔是预防和治理水灾的重要手段。结合母杜柴登矿顶板探放水工程，阐述了利用定向钻进技术施工探放水钻孔的工艺方法。实践证明，定向探放水钻孔可以准确地探测出目标区域的含水信息，完全满足矿区探放水要求，为煤矿安全生产提供了保障。

Abstract:

Flooding is one of the three major dangers that threaten the safety production in coal mine. Exploring and discharging borehole construction is an important means to prevent and deal with flooding. The article elaborates the construction process of exploring and discharging borehole with directional drilling technology. The practice proves that by means of the directional exploring and discharging borehole, water information of target area may be accurately detected, which meets the requirements of water exploring and discharging in mine and provides technical support for safety production.
