| 摘 要： | 煤炭是我国最主要的能源之一,如何高效开采开发和利用煤炭资源,是科学界的一个重要议题。受原生沉积条件影响,煤中可以含有多种共伴生矿产资源,部分共伴生矿产的价值甚至超过煤炭本身。山西省河东煤田是我国重要的优质炼焦煤生产基地,煤质好、煤炭储量巨大。在收集整理河东煤田煤中镓已有化验数据分析研究的基础上,分析了河东煤田煤中的镓分布规律和工业前景,发现河东煤田煤中镓在横向上总体呈现北高南低的趋势;纵向上,山西组煤中镓的含量显著高于太原组;在煤层内部,又存在垂向差异,即煤层下部煤中镓的含量高于上部煤中镓的含量。研究认为,物源区的距离是影响河东煤田煤中镓南北差异的一个重要因素;聚煤环境差异可能是影响河东煤田煤中镓含量差异的重要原因;原煤灰分差异可能是导致河东煤山西组和太原组煤层垂向差异的主要因素。从工业前景来看,河东煤田北中部矿区山西组下部地层煤中镓接近工业品位,具有一定开发潜力。

| Abstract: | Coal is one of the most important primary energy sources in China. How to efficiently exploit and develop coal resources is an important issue in scientific community. Affected by original deposition conditions, coal can contain a variety of associated mineral resources, the value of some associated minerals is even more than the coal resource itself. Hedong coal field in Shanxi province is an important production base with high-quality coking coal with a huge coal reserves in China. Based on the data analysis of gallium in Hedong coal field, distribution rule and industrial prospect of gallium in Hedong coal field have been analyzed. It is found that the gallium concentration in Hedong coal field is generally higher than that in Taiyuan formation in the vertical direction. In the coal layers, there are vertical differences, that is, coal contents of gallium in the lower part of coal layers are higher than in the upper part. It is concluded that the distance of provenance area is an important factor affecting the contents of gallium in north and south part of Hedong coalfield; the differences of coal-accumulating environment may be the main reason casuing the differences of gallium content, and the ash content difference may be the main factor causing the differences of Hedong coalfield in Shanxi formation and Taiyuan formation vertically. From the perspective of industry, gallium in the lower part of Shanxi formation in the north and central part of Hedong coalfield is close to industrial grade and has good development potential. |
