空气潜孔锤钻进技术在乌蒙山地下水探采结合工程中的应用

Application of Pneumatic DTH Drilling Technology in Wumeng Mountain Groundwater Exploration and Production Project

乌蒙山地下水探采结合工程是将水文地质调查中的水文地质勘探与供水井施工相结合的一项国家重点扶贫项目,该项目50余口探采结合井的施工解决了超过5万人的生活饮用水问题,取得了良好的社会经济效益。空气潜孔锤钻进技术在该项目中发挥了重要作用。文章介绍了空气潜孔锤在水文水井钻探中的技术优势,重点阐述了该项技术的施工工艺、设备选型以及典型复杂情况的处理,并提出了该项技术在水文水井施工方面的下一步研究方向。

Wumeng mountain groundwater exploration and production is a national key poverty alleviation project, combi- ning hydro-geological investigation with water supply well construction, this project provided drinking water for more than 50 thousand people by more than 50 constructed exploration wells. Pneumatic DTH hammer has played important role in this project; this paper describes its technical advantages, introduces this drilling technology about the construction process, e- quipment selection and the typical complex conditions treatment, and puts forward the research direction of this technology in hydrology and water well construction in nest step.
