摘　　要：山西省河保偏矿区为晋北煤炭基地的一部分,主采煤层13 ^(#) 属于太原组海陆交互相沉积。通过对河保偏矿区13 ^(#) 煤层剖面采样测试及垂向完整剖面的煤岩、煤质特征分析,13 ^(#) 煤层垂向显微组成变化特征反映出成煤植物类型、成煤时期的气候以及泥炭聚集环境。13 ^(#) 煤层成煤环境以干燥森林泥炭沼泽为主,覆水程度低,植物组织凝胶化程度不高。工业分析测试数据显示该煤层属于低灰分、低硫分、中高挥发分煤。结合这些煤岩煤质指标进一步分析认为,13 ^(#) 煤的清洁利用方式为液化用煤。The Hequ-Baode-Pianguan mining area is a part of northern Shanxi coal base.The main mineable coal No.13 belongs to the Taiyuan Formation,a marine and terrestrial interactive facies deposit.Through coal No.13 section sampling,testing and vertical integral section petrographic and quality features analysis has considered that the vertical maceral variation features have reflected coal-forming plant types,climate and peat accumulation environment during the coal-forming age.The coal-forming environment has been mainly droughty forest peat bog with low water coverage and low plant tissue gelatination degree.Proximate analysis data have shown that the coal belongs to low ash,low sulfur,and medium to high volatile matter coal.Combined with coal petrographic and quality indices and further analysis have considered that the clean utilization way of coal No.13 is for liquefaction.
