| 摘 要： | 以淮北煤田二叠纪10、7、3煤层样品为研究对象，采用仪器中子活化法（INNA）测试了煤中42个伴生元素的含量，将其与华北石炭-二叠纪和中国煤中的伴生元素含量、范围进行了对比，并对伴生元素中主量元素含量和灰分的关系、微量元素的共生组合特点以及稀土元素含量与灰分的关系、稀土元素分布模式进行了初步分析。结果表明，对环境有影响的Ba、Co、Cr、Cu、Mo、Th、V、W、Zn、Ti元素在研究区煤中相对富集，Al、Ti、K、Na等元素与灰分有较好的相关性，Ca、Mg、Fe和灰分的相关性较差，稀土元素与灰分正相关且具有相似的分配模式，普遍存在Eu亏损现象，说明煤中伴生元素的主要来源是陆源物质。

| Abstract: | Some samples were collected from Permian 10 th , 7 th and 3 rd coal seams in the Huaibei Coalfield, and the contents of 42 elements were determined by the instrumental neutron activation analysis (INNA). The distribution and variation ranges of the elements in the samples were compared with those of the Carboniferous- Permian coal from North China and the Chinese coals, and the relationship between the elements and ashes, the association characteristics and the distribution patterns were analyzed. The results show that the elements Ba, Co, Cr, Cu, Mo, Th, V, W, Zn and Ti are relatively abundant in the coal field. There exists a positive correlation between Al, Ti, K, Na and ashes, but things are quite opposite for Ca, Mg and Fe. Almost all rare earth elements are in a positive correlation with the ash and have similar distribution patterns, characterized by obvious Eu negative anomalies. It is thus concluded that the sources of the associated elements are terrigenous materials. |
