注浆材料与钻井液材料在大斗沟煤矿钻孔施工中的应用

Application of Grouting Materials and Drilling Fluid Materials in Dadougou Coal Mine

注浆材料和钻井液材料的联合应用对特殊地质条件下钻孔施工的顺利进行极为重要。针对大斗沟煤矿工程地质特点,文章通过钻孔地层岩性与水文地质特性分析,结合钻孔结构,提出注浆材料与钻井液材料综合应对方案。实践表明材料应用效果良好,该材料方案对于类似地层钻孔施工有一定的参考价值。

The joint application of grouting material and drilling fluid material is very important for drilling construction under special geological conditions. At the engineering geological characteristics of Dadougou coal mine. Through the drill strata lithological and hydrogeological characteristics analysis, combined with borehole structure, the paper puts forward the application scheme of grouting material and drilling fluid material. The practice shows that the materials and the application effect is good, the material scheme for similar borehole construction has a certain reference value.
