对采自辽宁沈北煤田的７个刻槽煤样，应用电感耦合等离子体原子发射光谱（ＩＣＰ－ＡＥＳ）与仪器中子活化分析（ＩＮＡＡ）测定煤中８个氧化物与２０个微量元素的含量．与中国煤、美国煤、世界煤中元素质量分数对比表明：沈北煤田煤中大部分元素质量分数处于正常水平，而Ｎａ，Ｃｏ，Ｃｒ，Ｃｕ，Ｎｉ与Ｓｃ的质量分数偏高，且Ａｓ，Ｃｏ，Ｃｕ与Ｎｉ在煤中明显富集，分析认为煤中Ｃｒ和Ｎｉ质量分数较高且富集的主要原因与煤系基底橄榄玄武岩有关．相关与聚类分析以及扫描电镜能谱（ＳＥＭ－ＥＤＸ）分析显示：Ｃｏ，Ｍｏ和Ｓｎ与粘土矿物有关；Ｂｅ，Ｂｒ，Ｐ，Ｍｎ与Ｖ显示出有机亲和性；Ａｓ，Ｐｂ，Ｔｈ，Ｕ和Ｚｎ与硫化物矿物有关；Ｃｒ，Ｃｕ与Ｎｉ可能与硫化物矿物有关；Ｂａ，Ｃａ，Ｓｂ和Ｓｅ与碳酸盐矿物有关．此外，还预测了Ａｓ，Ｂｅ，Ｃｒ，Ｃｕ，Ｎｉ与Ｚｎ等有害元素在用物理洗选方法进行脱除的效率
In this paper, seven of the seven grooved coal samples collected from Shenbei Coalfield in Liaoning Province were measured by inductively coupled plasma atomic emission spectrometry (ICP-AES) and instrumental neutron activation analysis (INAA) to measure the content of 8 oxides and 20 trace elements in coal content. Compared with the mass fraction of Chinese coal, coal and coal in the world, most of the coal mass fraction in Shenbei coal field is at normal level, while the mass fraction of Na, Co, Cr, Cu, Ni and Sc is high, and As , Co, Cu and Ni were obviously enriched in coal. The main reason for the high concentration and enrichment of Cr and Ni in coal is that coal-based basal olivine basalt is concerned. Correlation and cluster analysis as well as SEM-EDX analysis showed that Co, Mo and Sn were related to clay minerals; Be, Br, P, Mn and V showed organic affinity; As, Pb, Th, U and Zn are related to sulfide minerals; Cr, Cu and Ni may be related to sulfide minerals; and Ba, Ca, Sb and Se are related to carbonate minerals. In addition, the efficiency of removal of harmful elements such as As, Be, Cr, Cu, Ni and Zn by physical washing was also predicted
