神府东胜矿区煤中微量元素初步研究

PRELIMINARY STUDY ON THE TRACE ELEMENTS IN COALS OF DONGSHENG MINING DISTRICT, SHENFU COALFIELD

摘要: 采集神府东胜矿区延安组5个可采煤层732个煤心煤样,应用光谱、原子荧光、原子吸收等分析方法,测定了煤中23种微量元素。阐述了微量元素在煤中的含量分布和微量元素相对于地壳丰度的富集系数,并对有害元素和有用元素进行了初步评价。

Abstract: 732 core samples are sampled from five minable coal seams in Yan'an formation in Dongsheng Mining District,Shenfu coalfield.23 trace elements in coals are determined using spectroscopy,atomic fluoroscopy,atomic absorption methods.The contents and distributions of trace elements in coals and the enrichment coefficients of trace elements relative to the crust abundance are expounded,and the hazardous and useful elements are evaluated preliminarily.
