空气潜孔锤钻进技术在铝土矿钻探施工中的应用试验

Application Experiment of DTH Hammer Drilling in Bauxite

摘要:

详细介绍了在铝土矿区进行空气潜孔锤钻进技术的应用试验。试验结果表明：该技术与普通双管钻进技术相比平均时效提高5.1倍，最高时效可达15.33 m。通过试验得出了几点认识，为在铝土矿区进一步推广应用空气潜孔锤钻进技术积累了实践经验。

Abstract:

This paper introduces the application experiment of DTH hammer drilling in bauxite. The result shows that this technology can improve the drilling efficiency by 5.1 times than the common double drilling (double drilling with single-motor), and its best efficiency can reach to 15.33 m/h. Some valuable experiences have been accumulated for the further promotion of DTH hammer techniques.
