Abstract: The class maps or contour maps of some indexes of coal quality in mineable coal seam of Taiyuan formation and Shanxi formation in Shanxi province we re drawn based on large amount of data on coal qualities collected from Shanxi province, and furtherly the distribution of six indexes were also discussed.The results s how that the ash content in Taiyuan formation increase from South to North and decrease from West to East, and the sulfur content increase from North to South, which have obvious zonation.For Shanxi formation, the change of ash content is high to low from North to South, and the sulfur content is low.The volatile matter yields in coal are high to low from North to South and from West to East.The caking index has a trend which increases from South to North and from East to West.Furthermore, the c entre of Huoxi coalfield had high caking index values .All the results indicat that the degree of metamorphism of coal becomes gradually increase from North to South an d from West to East.The change trends of coal types are from bituminous to anthracite.The calorific values (Qgr, d) are more than 27 MJ/kg.The super-high calorific val ue are found in most coal areas.The obtained results can provide scientific basis for evaluation and reasonable utilization of coal resources in Shanxi Province.
