Geochemical Characteristics of Coal in the Taiyuan Formation in the Center and North of the Xishan Coalfield

The Xishan coalfield is an important coking coal-producing area in China. No. 8 and 9 coals of the Taiyuan formation were sampled tested from nine mines center north coalfield, coal’s quality characteristics, element occurrence enrichment sedimentary environment characteristics analyzed to provide a foundation for clean efficient coal utilization identification associated resources. results obtained experiment show that Li element. coefficient U ML8 13.78, which close industrial index recycling. hazardous elements are Cu, Mo, Cd ML8, Mo DQ8, Th ZCD8. Along with K value Sr/Ba ratio, seawater has greater influence on south than east west. (except ML8) was formed under oxidation based U/Th, Ni/Co, V/Cr ratios. or suboxic dysoxic resulted coal. Based Al2O3/TiO2 sediments mainly felsic volcanic rocks.
