摘要: 对梅山矿区煤灰的化学成分、微量元素分布及煤灰的岩石学特征等进行了详细研究, 并讨论了微量元素与三
态硫、挥发分的相关性。研究结果表明, 梅山矿区煤为中低磷煤, 煤中U 元素的含量低于地壳中的平均含量, 煤中Ge
和Ga 的含量略高于地壳中的平均含量。煤中微量元素的赋存状态对煤炭的加工利用和燃烧工艺起着重要作用, 并能为
其成因提供相关地质信息, 同时还决定了其对环境的影响程度及其可能的工业利用价值, 因此还分析了矿区煤中U,
Ge, Ga 等元素的赋存状态。

Abstract: This paper made a detailed study on the chemical composition, trace element distribution and petrological characteristics
of coal ash in Meishan mining area, and discussed the correlation between trace elements and three state sulfur and volatile
matter. The results show that the coal in Meishan mining area is medium-low phosphorus coal, the content of U in coal is lower
than the average content in the crust, and the content of Ge and Ga in coal is slightly higher than the average content in the crust.
The occurrence state of trace elements in coal plays an important role in the processing and utilization of coal and combustion
technology, and can provide relevant geological information for its genesis, and also determine its impact on the environment and
its possible industrial value. Therefore, it also analyzed the occurrence of U, Ge, Ga and other elements in coal.
Key words: Meishan mining area; trace elements; distribution regularities; occurrence state
