在收集山西省煤田大量煤质资料的基础上,绘制了该省太原组和山西组煤层主要煤质指标的等级图或等值线图,在此基础上分析了6种指标的分布规律。结果表明:太原组的煤中灰分有北高南低、西高东低的特点,而煤中硫分则南高北低,分带明显;山西组从北往南灰分产由高到低变化,具有明显的分带性;而煤中硫分多为低硫煤。煤中挥发分总体上呈北高南低、西高东低的特点。煤的黏结指数亦呈北高南低、西高东低的趋势,其中霍西煤田中部均为高值中心,反映了煤的变质程度由北向南、由西向东逐渐变高,煤类由烟煤向无烟煤变化的趋势。原煤干燥基高位发热量大于27 MJ/kg,且大部分区域属于特高热值煤,结果为评价和充分合理利用山西省的煤炭资源提供了科学依据。

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.
