| 摘 要： | 以哈密矿区、淮北煤田为例，对煤的变质程度与稀土元素特征之间的关系进行了初步研究，结果表明：哈密矿区变质程度相同的煤具有不同稀土元素特征，淮北煤田不同变质程度煤的稀土元素特征基本一致，这表明变质作用对煤的稀土元素不产生影响；稀土元素含量与灰分正相关，表明煤中稀土元素含量主要取决于煤的无机组分含量；稀土元素分布模式与华北晚古生代沉积的特征是一致的，表明煤样稀土元素分布模式是由源岩继承下来的。

| Abstract: | Relationship between coal ranks and REE(rare earth element) features in both Hami and Huaibei coal was researched. The result shows that, in Hami, coals with the same rank have different features of REE; While in Huaibei, the features of REE are basically the same, showing that the coal rank has no influence on REE. The content of REE is closely related to ash content, indicating that the REE content depends mainly on inorganic matter. The distribution pattern of REE is in accordance with the characteristic of Late Paleozoic sediments in North China platform, reflecting that it is inherited from the source rock. |
