摘要
This research summarize the coal quality and its distribution in the Eastern Junggar coalfield by coal petrology and coal chemistry.The coals have medium moisture and low ash contents,medium-high volatile matter yield,and low S,P and Cl contents.The ash and vitrinite contents in the eastern of this coalfield are relatively higher than those in the western.The high inertinite and low ash contents in Eastern Junggar coals are due to that aggregation rate of peat is relatively rapid than subsidence rate of the basement,the surface of the peat bog was above the water level,and was characterized by relatively oxidizing and stable raised bog,with low detrital influence,during the peat bog accumulation period.In the eastern part of the coalfield,the ash and the vitrinite contents are relatively higher due to the relatively high subsidence rate of the basement and high detrital supply.
