|
摘要
本文结合空气潜孔锤钻进技术在七角井矿区充填孔施工中的应用实例,介绍了充填孔的施工设备配置、钻进工艺参数、施工保证措施。同时对充填孔施工难点、空气潜孔锤钻进技术特点、应用效果等方面进行了分析阐述。实践表明,空气潜孔锤钻进技术具有施工工艺简单,施工速度快,施工周期短,钻孔质量高等特点,在坚硬基岩大口径充填孔施工中具有广阔的应用前景。
Combining with the application of air DTH hammer drilling technology in filling hole construction in Qijiaojing mining area, this paper introduces the construction equipment configuration, drilling parameters and construction guarantee measures of filling hole. At the same time, the difficulties of filling hole construction, the technical characteristics of air DTH hammer drilling and its application effect are analyzed and expounded. The practice shows that the air DTH hammer drilling technology has the characteristics of simple construction technology, fast construction speed, short construction period and high drilling quality. It has broad application prospects in the construction of large diameter filling holes in hard bedrock.
