摘　　要：近年来,随着业主方对钻孔采铀控制溶浸范围的要求越来越精细,地浸工艺钻孔施工由填砾式钻孔演变成开窗式切割钻孔,国内几乎无相关钻孔施工经验可寻。开窗式切割成井工艺尚属于新技术范畴,对于该类钻孔施工,施工单位只能不断摸索,寻找相匹配的钻探设备及施工方法,积累施工经验。本文结合伊犁地浸工艺钻孔施工,分析钻孔开窗切割的施工方法,以指导具体实践。In recent years,as the owner’s requirements for controlling the leaching range of uranium from borehole mining have become increasingly sophisticated,in-situ leaching drilling has evolved from gravel filling drilling to window cutting drilling,and there is almost no relevant drilling experience available in China.The well completion technology of window cutting is still a new technology,for this kind of drilling construction,the construction unit can only constantly explore,find matching drilling equipment and construction methods,and accumulate construction experience.Combined with the drilling construction of Yili in-situ leaching process,this paper analyzes the construction method of drilling window cutting to guide the specific practice.
