摘要
煤中微量元素的赋存规律和综合利用工艺的研究和开发,对于资源的合理利用具有重要意义。在综合国内煤中微量元素研究文献的基础上,分析了煤中微量元素的来源可分为原生、次生和后生,赋存状态主要与有机质的吸附和络合作用有关;开发利用的现状较为落后,表现为研究区域少、研究手段和技术水平差。指出,必须深入对煤中微量元素的赋存规律和综合利用工艺进行深入研究,合理利用资源,使矿区实现可持续发展。
The law of trace elements in coal and their research and development was important to utilization of resources. On the basis of the research of trace element in coal in China, the origines of trace elements in coal were primary, secondary and epigenetic, rune occurrence of trace elements was adsorbed or complexed by orgaric substance and the utilization of trace elements was behindhand. The problem at present lay in the lacking of studying area and the method was out of date. To make use of it in reason, the study on the law of mode of occurrence and utilization of trace elements in coal should be given emphases to.
