| 摘 要： | 大南湖煤田北露天煤矿区位于新疆自治区哈密市南部，地处天山—兴安岭地层区大南湖坳陷内，具有良好的成煤地质条件。由于研究区以往研究程度较低，同时煤层较多且较为复杂，制约了煤田的综合开采。采用地球物理测井对研究区开展研究工作，对矿田西山窑组中段16、18、19、20、21、22、22下、23、25、27、28、29、30等主要煤层进行对比、解释，同时利用地球物理测井曲线对ZK5-6的构造形态进行研究，发现在19煤层与21上煤层间存在落差为15 m的正断层，在22煤层与25煤层间也存在落差为10 m的正断层，为煤层开采提供了重要依据。

| Abstract: | The north open-pit coal mine area of Dananhu Coalfield is located in the south of Hami City，Xinjiang Autonomous Region，in the Dananhu Depression of Tianshan-Xing′anling strata area，and has good coal-forming geological conditions.Due to the low level of research in the study area in the past，and at the same time，there are many and more complex coal seams，which restrict the comprehensive mining of coal fields.It was used geophysical logging to carry out research work in the study area，and conduct research on major coal seams such as No.16，No.18，No.19，No.20，No.21，No.22，No.22 lower，No.23，No.25，No.27，No.28，No.29，No.30 in the middle section of Xishanyao Formation in the minefield.Comparing，explaining，and using geophysical logging curves to study the structure of ZK5-6，it was found that there was a normal fault with a drop of 15 m between the No.19 coal seam and the No.21 upper coal seam，and there was also a drop between the No.22 coal seam and the No.25 coal seam.It was a 10 m normal fault and provided an important basis for coal mining. |
