    • Abstract
  • Based on the large number of chemical analysis data,it is analyzed that the horizontal and vertical distribution characteristics of trace elements in coal of Tangkou District.The distribution regularities of trace elements in coals,which are of different grain sizes and different densities, are researched preliminarily.The influencing factors on enrichment of trace elements are discussed,too The results would be important for future comprehensive development and utilization of coals in this district.
