摘　　要：潜孔锤钻凿技术,是利用空气为动力,冲击全面破碎岩石,空气或泡沫作为循环介质,排出岩粉和润滑冷却钻具,该技术施工用水少,适合缺水、严寒地区作业,且钻进速度快,凿井质量好。文中结合盂县水井工程施工实践,阐述了潜孔锤凿井的钻进工艺、钻进参数、技术措施等细节。Well-drilling technique of downing hammer in hole is such a technique in which compressed air is used as energy to percuss and break down rock,foam agent with water and compressed air are taken as circle mediums to drain rock powder from well and to lubricate drilling machine.Because of using less construction water,this technique is suited in severely cold and water shortage regions and due to using this technique,the drilling speed is quickened,the drilling quality is good.In combination with the construction practice of Yu County's well project,the article expounds this technique's drilling method,drilling parameters and technical measures.
