摘要
在大量化验测试资料的基础上，分析了唐口区煤中微量元素在平面上的变化特征和在不同煤中或同一煤层在垂向上的变化规律，并初步研究了微量元素在不同粒度和不同密度煤中的分布特征，探讨了煤中微量元素富集的原因，为今后煤的综合开发和利用提供了参考资料。
Based
on the large number of chemical analysis data,it is analyzed that the horizontal and vertical
distribution characteristics of trace elements in coal of Tangkou District.The distribution
regularities of trace elements in coals,which are of different grain sizes and different densities,
are researched preliminarily.The influencing factors on enrichment of trace elements are
discussed,too The results would be important for future comprehensive development and
utilization of coals in this district.
