摘要
通过对韩城燎原矿的11#煤不同深度的煤样中的微量元素P、U、Ge和Ga进行分析,发现为11#煤低磷煤;煤中U和Ga的含量均低于地壳中的平均含量,只有Ge含量略高于地壳中的平均含量。计算了这些微量元素与三态硫、灰分和挥发分的相关关系。结果表明Ga在煤中主要以无机态存在。P在煤中可能大部分以有机态存在,小部分以无机态存在。U与Ge在煤中可能主要以有机态存在,以无机态存在的可能性较小。
Trace elements（P,U, Ge,Ga） in 11 # coal of Liaoyuan mine in Hancheng were analyzed by examining coal samples of different seams. The result shows that the content of P in 11 # coal is low; the content of U and Ga is lower than that in earth crust, and only the content of Ge is higher than the mean value in earth crust. In addition, the correlations of trace elements, the species of sulfur and ash composition are analyzed. The studies suggest that Ga in coal is mainly associated with inorganic matter, but U and Ge in coal are stronger affinities to organic matter. The most part of P in coal is associated with organic matter,but small part of P in coal is inorganic matter.
