摘要(Abstract)：

为评估进口煤对国内环境的影响,采用原子荧光光谱、直接测汞仪、离子色谱、电位滴定等对360批蒙古国煤炭中的灰分、硫、汞、砷、氟、氯、磷含量进行了测定,用稳健统计等方法描述了7项指标的整体水平,并根据我国煤炭相关分级标准和富集系数进行了评价。蒙古国煤炭总体为特低汞、特低氯、低灰、低硫、中氟、中砷、中磷煤,砷的平均富集系数均为16,其环境迁入风险值得关注。利用相关分析与聚类分析推断了硫、汞、砷、氟、氯、磷的赋存形态,360批蒙古国煤炭可分为三大类,可能存在3种不同的矿脉来源,具有不同的特征。综合考虑相关分析与因子分析结果,主因子特征可描述为有机态砷伴生矿物因子、含氟矿物(氟磷灰石和硅铝酸盐)因子和硫因子。
To assess the impact of imported coal on the domestic environment,the contents of ash,sulfur,mercury,arsenic,fluorine,chlorine and phosphorus in the imported 360 batches Mongolia coals were detected by Atomic Fluorescence Spectrometry( AFS),Direct Mercury Analyzer and Potentiometric titration.The overall level of the seven elements was described by the robust statistics and then evaluated according to the China's coal related grading standards and enrichment factor.The results show that the Mongolia coals contains special low mercury and chlorine,low ash and sulfur,medium fluorine,arsenic and phosphorus.The average enrichment factor of arsenic is 16,which should be payed more attention to the risk of environmental pollution.The relevant analysis and cluster analysis were used to infer the occurrence status of sulfur,mercury,arsenic,fluorine,chlorine and phosphorus.360 batches Mongolia coals can be divided into three different veins sources,and has different characteristics.Comprehensive consideration of correlation analysis and factor analysis results,the main factor features cloud be described as organic arsenic associated factor,fluorine mineral factors( fluorophosphorite and aluminosilicate) and sulfur factor.
