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.
