| 中文摘要:定向钻探技术在固体矿产中的应用，其技术意义体现在控制钻孔轨迹，使孔斜或钻孔截矿点满足地质勘探要求，经济意义体现在准确揭露矿层及其边界关系，提供更为准确的矿产储量报告。黑龙江省东宁县金厂矿区J14ZK0100孔实施分支孔进行固体矿产勘探取得成功，大幅节约了钻探工作量，并积累了宝贵的经验。在分析矿区定向钻进施工难点的基础上，介绍了技术措施和施工效果。 |

| Abstract:For the application of directional drilling in solid mineral exploration, it is technically intended to control borehole trajectory to make the inclination of the borehole or the intersection point of the borehole to meet the geological exploration requirements; and economically is desired to expose the deposit and its boundary for accurate definition of ore reserves. The successful solid mineral exploration was made in J14ZK0100 with branch hole in Jinchang mine in Dongning of Helongjiang Province, the drilling works was greatly saved and valuable experience was accumulated. On the basis of the analysis on the difficulties in directional drilling construction, the paper introduces the technical measures and construction effects. |
