摘　　要：针对同发东周窑矿地质条件复杂,煤层赋存不稳定及地质构造较发育的问题,通过利用层序地层学方法研究井田内石炭-二叠系地层特征,建立石炭-二叠系(煤系)高分辨率层序地层格架,研究煤系地层沉积环境、沉积微相和聚煤模式,构建一种可厘定复杂断层构造及煤层赋存规律的综合分析体系,对矿区范围内含煤岩系沉积微相及煤层进行精细对比,总结煤层成因及煤层赋存特征,进一步提高地质预报的精确度。In response to the complex geological conditions,unstable coal seam occurrence,and welldeveloped geological structures in Tongfa Dongzhouyao mine,the characteristics of the CarboniferousPermian strata in the mine field were studied using sequence stratigraphy methods.A high-resolution sequence stratigraphic framework of the Carboniferous-Permian(coal series)was established to study the sedimentary environment,sedimentary microfacies,and coal accumulation patterns of the coal series strata.A comprehensive analysis system was constructed to determine the complex fault structures and coal seam occurrence patterns,Fine comparison of sedimentary microfacies and coal seams within the mining area,summarizing the genesis and occurrence characteristics of coal seams,and further improving the accuracy of geological prediction.
