摘　　要：依据煤质测试结果,对城子河组14号煤的煤质特征进行了研究,结果表明14号煤以高镜质组含量、高挥发分产率、低灰分产率、特低水分含量和特低硫分含量为特征;依据挥发分产率可划分为高挥发分A烟煤。高的镜质组含量归因于成煤期盆地基底沉降速率相对较快,沼泽面长期处于地下水潜水面之下而具有相对还原的环境。灰成分参数和硫含量指示成煤环境为陆相环境,但沼泽环境具有较弱的还原环境。Based on the results of coal quality, the paper investigates coal quality of the No.14 coals of the Chengzihe Formation to indicate that the studied coals are characterized by high vitrinite content, high volatile yield, low ash yield, sepicial-low moisture content and low sulfur content. The coals are classified as high volatile A bituminous coals following the ASTM classification. The high vitrinite content in coals is ascribed to relative high subsidence rate of basin base, which makes peat have relatively high groundwater table. The ash compositional indices and sulsur content suggest a terrigenous coal-forming environment showing relatively low reducing condition.
