The abundance of one major and eight trace elements in 215 coal samples from the Mengjiawan exploration area, northern Shaanxi, China, were determined. As compared with Chinese coal, American coal and coal Clarke value, only Th content in the Mengjiawan coal is high. The abundance of the element is different in every coal-seam. The highest contents of Cl(43mg/kg), Ge(7mg/kg), and Th(20mg/kg) occur in the coal seam No.5-2, while the highest contents of F(108mg/kg) in coal seam No.3-1. The elements were divided into two groups based on their coal seam distribution, and the characteristics of each group were discussed.
