研究了鲁西含煤区中部新汶和肥城煤田煤的岩石学、煤化学、煤矿物学和煤地球化学特征。研究成果表明山西组煤层和太原组煤层在煤岩学、煤化学、煤矿物学和煤地球化学特征方面存在较大差异 :山西组煤层比太原组煤层具有相对高的惰质组和壳质组含量 ,相对低的镜质组含量 ;山西组煤层比太原组煤层具有相对低的灰分和硫含量以及挥发分产率 ;山西组煤层具有相对低的矿物含量 ,而太原组煤层具有相对高的矿物含量。山西组煤层和太原组煤层之间的常量和微量元素含量差异 ,以及煤层和地层层序中常量和微量元素的垂向变化也被讨论。
The petrology, coal chemistry, coal mineralogy and coal geochemistry of coal in Xinwen and Feicheng coalfields in the central Luxi coal-bearing area were studied. The research results show that the coal seams of Shanxi Formation and Taiyuan Formation have great differences in the features of coal petrology, coal chemistry, coal mineralogy and coal geochemistry. The coal seams of Shanxi Formation have a relatively higher inertinite and crust than the Taiyuan Formation Content and relatively low vitrinite content. The coal seam of Shanxi Formation has relatively lower ash and sulfur content and volatile matter yield than the coal seam of Taiyuan Formation. The coal seam of Shanxi Formation has relatively low mineral content, while the coal seam of Taiyuan Formation has relatively high mineral content content. The differences of the contents of the constants and trace elements between the coal seams of Shanxi Formation and Taiyuan Formation and the vertical variations of the constants and trace elements in the coal seams and stratigraphic sequences are also discussed.
