摘要
The petrographic characteristics and facies of the high-sulfur coal (No. 9 coal seam) in Wuda coalfield were analyzed and the washability of stratified coal samples formed in the different coal facies was discussed using the density component method of coal petrology. The results show that the washability of different stratified coal samples in tbe same coal facies is similar, and the accumulating environment of peat swamp controlls the contents and the occurrence of minerals, and thus controll the coal washability. The washability or the stratified coal formed in high peat swamp is better than that formed in low peat swamp.
