为获得高兴庄煤矿主采煤层中有害微量元素的分布和赋存形态，对采自同一工作面上6个分层煤样的工业分析和15种微量元素的含量进行统计。根据各有害元素在工作面垂直方向上的变化特点以及相关性分析发现：大部分元素的最高浓度值出现在煤层的顶部或底部，与灰分的垂直分布相似，尤其是元素 Ba 和 Sr；元素 Ba、Sr、Ti、Mn 和 Ni 主要以无机形式赋存；元素 Cr、Mo、Zn 和 Tl 趋向于负载在煤的有机质中。以硫酸盐、碳酸盐矿物和粘土矿物为主要无机载体赋存的元素有 Sr、Ba 和 Ti；以硫化物为主要无机载体赋存的元素有 Pb、Cd、Cu、Be、Co、Zn、Ni、Mo、Ga 和 Mn；此外 Mn 也可能负载在碳酸盐矿物中。

In order to research the distribution and occurrence mode of toxic trace elements in primary mineable coal seam of Gaoxingzhuang Coal Mine,the proximate analysis for 6 coal samples from different positions of a same working face and the contents of 15 kinds of trace elements from these sam-ples were evaluated. According to the variation features and correlation analysis of each toxic trace ele-ment in vertical direction of working face,there were the maximum concentration values for most ele-ments in the top and bottom of coal seam,especially the elements Ba and Sr,which was similar with the vertical distribution of ash content. The elements Ba,Sr,Ti,Mn and Ni were mainly existed in inor-ganics.The elements Cr,Mo,Zn and Tl had a tendency to be carried in organic matter in coals.The main mineral carriers of elements Sr,Ba and Ti were sulfate,carbonate and clay minerals.The main mineral carriers of elements Pb,Cd,Cu,Be,Co,Zn,Ni,Mo,Ga and Mn were sulfide minerals.The elements Mn may also occur in carbonate minerals.
