摘　　要：目前定向钻进技术已广泛应用在煤矿瓦斯治理、探放水和地质勘探等方面,但施工成本高,钻孔复合作用欠缺成为共性问题。本文重点讲述安阳主焦煤矿2301工作面定向地质勘探孔的钻进工艺,不仅探清断层和煤层赋存条件,钻孔后期又可作为探放水孔和顶板高位抽放孔重复使用,旨在说明定向钻进技术“一孔多用”的复合功能和优越性,望为进一步发挥定向钻进技术的优势提供借鉴。Directional drilling technology has been widely used in coal mine methane control,water ex-ploration and drainage,and geological exploration.However,the high construction cost and lack of com-pound functions for drilling boreholes have become common problems.This paper focuses on the drilling process of directional geological exploration boreholes in the 2301 Working Face of Zhujiao Coal Mine in Anyang.The borehole not only figures out the fault and coal seam occurrence conditions but also allows the holes to be reused as water exploration and drainage boreholes and high-position gas extraction bore-holes in the roof after drilling.The aim is to demonstrate the composite functions and advantages of“one hole for multiple uses”directional drilling technology and to provide a reference for further leveraging the advantages of directional drilling technology.
