摘　　要：采用原子荧光、直接测汞仪等对唐山港进口的160批朝鲜无烟煤中的灰分、硫、汞、砷、氟、氯、磷含量进行了测定,用稳健统计描述了灰分(Ash)等的整体水平,并根据我国煤炭分级标准及富集系数进行了评价;用因子分析寻找和确定了整体主要特征;通过数据挖掘,用相关分析、聚类分析等方法对硫、汞等的赋存形态进行了推断。唐山港进口朝鲜无烟煤总体为特低硫、特低氯、低磷、低砷、低灰、中氟、高汞煤;主因子特征可描述为汞-砷、灰分和磷、砷、汞的平均富集系数均为6,其环境迁入风险值得关注。160批朝鲜无烟煤可分为两大类,可能存在两种不同的矿脉的来源,具有不同的特征。The contents of ash,sulfur,mercury,arsenic,fluorine,chlorine and phosphorus in the imported 160 batches of Korean anthracite coals in Tangshan port were detected by Atomic Fluorescence Spectrometry（ AFS）,Direct Mercury Analyzer,etc. The overall level of ash etc was described by the robust statistics and evaluated by the china＇s coal related grading standards and enrichment factor. The factor analysis was used to find and determine the overall main features. Data mining,relevant analysis and the cluster analysis were used to infer the occurrence status of the elements. The results showed that the Korean anthracite coals imported in Tangshan port had special low sulfur,special low chlorine,low phosphorus,low arsenic,low ash,medium fluorine and high mercury in the overall level. The main factor characteristics could be described as Hg-As,Ash and phosphorus.The average enrichment coefficient of arsenic and mercury were 6,and their environmental immigration risk should be concerned. 160 batches of Korean anthracite coals could be divided into two categories. It indicated that there may be two different veins sources,which had different characteristics.
