| Abstract: | In this paper, the significance is expounded in the study of trace elements. The studied area and the methods of sample\|collection are introduced. On the basis of the analytical results the distribution characteristics of the trace elements in horizonal and vertical directions among different coal seams and in the same coal seam are discussed. The factors affecting the enrichment of trace elements in coals are analyzed. What is mentioned above would provide important reference for mining or utilizing coal in the Jining coalfield in the future. |
