Abstract：The coal samples from part of the production field in Zhundong coal field were taken to research the relationship between the coal petrographic characteristics, as well as the coal quality and the process performance.It is considered that inertinite group is the main maceral group, and the content of inertinite group is about 80% (no mineral containing), the semifusinite and fusinite are the main inerinite, desmocollinite is the main vitrinite. The exinite group content is relatively low, sporinite, cutininte and suberinite are the main exinite, and clay minerals is main mineral.The vitrinite content and volatile matter yield are positively related for Zhundong coal.The vitrinite content and the Hardgrove Grindability index of Zhundong coal are inversely related for Zhundong coal.The high inertinite group content is a favorable conditions for high calorific value of Zhundong coal. The high inertinite group content is the immediate cause of the low tar production rate.Inertinite group content of Zhundong coal is high, semifusinite and fusinite are the main inerinite, which are the reason of the developed pore structure, and the latter is the main formation cause for high moisture content, high reactivity in Zhundong coal.
