摘　　要：为正确区分腐泥煤与腐植煤的地球化学特征 ,对山东淄博煤田 1 0个地质勘探钻孔中共生的腐泥煤与腐植煤样品的水分、硫含量、发热量、灰产率及灰成分、微量元素等进行了分析测试和对比研究 ,研究表明与共生的腐植煤相比 ,大部分腐泥煤具有低硫、高灰、高密度、富含微量元素等特点。The basic chemical composition of coal and ash is an important but insufficient feature for reliable explanation of coal properties. The modes of occurrence of the elements, their origin and concentrations in coal, as well as their behavior during coalification are also very important parameters for coal quality. The noted characteristics may be a guide for prediction of some properties and behaviors of coal and their products. Sapropelic coal was derived from algae and herbs under special environments. The source material of sapropelic coal is obviously different from that of humic coal. There are great differences in geochemical characteristics between them. On the basis of identified samples of paragenetic sapropelic coal and humic coal from drilling holes, the moisture, sulfur content, heat value, ash yield and ash composition in these two types of coal have been studied comparatively.
