济宁煤田煤中微量元素的地球化学研究

GEOCHEMISTRY OF TRACE ELEMENTS IN JINING COALFIELD

阐述了研究煤中微量元素的意义 ,对研究区及采样方法作了介绍 ,在测试分析资料的基础上 ,探讨了济宁煤田煤中微量元素在各井田内的平面变化特征和微量元素在不同煤层、同一煤层中垂向上的分布变化规律 ,初步研究了煤中微量元素的赋存状态 ,分析了煤中微量元素富集的原因 ,为今后济宁煤田煤的综合开发和利用提供了重要的参考资料。

In this paper, the significance is expounded in the study of trace elements. The studied area and the methods of sample\|collection are introduced. On the basis of the analytical results the distribution characteristics of the trace elements in horizonal and vertical directions among different coal seams and in the same coal seam are discussed. The factors affecting the enrichment of trace elements in coals are analyzed. What is mentioned above would provide important reference for mining or utilizing coal in the Jining coalfield in the future.\;
