为探明老矿山的隐伏矿体和深部矿床，资源勘查中设计了一批深孔、斜孔。河南洛宁程家沟-沙沟银多金属矿区的矿体产状陡、矿脉集中，钻探设计多为分支孔，钻孔深、斜度大，如何保证钻孔质量，提高施工进度，成了施工难题。本文通过1550?m斜孔的施工实践，介绍了钻探设备的选择、改装，冲洗液技术研究，钻探工艺的选择及预防钻孔弯曲的具体措施，推广了中深斜孔施工的工艺技术。
為探明老礦山的隱伏礦體和深部礦床，資源勘查中設計瞭一批深孔、斜孔。河南洛寧程傢溝-沙溝銀多金屬礦區的礦體產狀陡、礦脈集中，鑽探設計多為分支孔，鑽孔深、斜度大，如何保證鑽孔質量，提高施工進度，成瞭施工難題。本文通過1550?m斜孔的施工實踐，介紹瞭鑽探設備的選擇、改裝，遲洗液技術研究，鑽探工藝的選擇及預防鑽孔彎麯的具體措施，推廣瞭中深斜孔施工的工藝技術。
