摘　　要：矿井综合钻孔测井技术能够将钻孔视频、岩性、孔斜、孔深4种数据源的信息进行综合分析,实现了高效的钻孔信息综合采集手段。在山西冀中荣泰煤业井下补勘钻孔的试验,通过对取得的钻孔视频、自然伽玛分析,得到钻孔轨迹、视频柱状、分析柱状等数据资料,该技术不仅可以有效避免由于钻探时无法准确判断岩性、层位、出水原因,发生误判的现象发生,还大幅度降低煤矿井下钻探工程的费用。该技术在山西冀中荣泰煤业的试验中取得了良好的效果,具有广泛推广应用价值。Integrated borehole logging technology in mines can synthesize and analyze the information from four data sources:borehole video,lithology,hole slope and hole depth,and realize an efficient means of integrated borehole information collection.In the test of the underground supplementary exploration borehole in Shanxi Jizhong Rongtai Coal Industry,through the obtained borehole video and natural gamma analysis,the data information of borehole trajectory,video column and analysis column were obtained.This technology can not only effectively avoid the occurrence of misjudgment due to the inability accurately judge the lithology,layer and water emergence reasons in drilling,but also significantly reduce the cost of underground drilling works in mines.This technology achieved good results in the test of Shanxi Jizhong Rongtai Coal Industry,with wide application value.
