摘要
煤中微量元素隐含着丰富的地质和成煤环境信息.研究煤中微量元素,对反演成煤环境、煤炭的高效清洁利用以及认识有害元素对人和生态环境的影响具有非常重要的意义.本文对贵州黔西市长江煤矿可采煤层中微量元素地球化学特征及成煤环境进行了分析,结果表明:长江煤矿可采煤层形成于浅水富氧环境;可采煤层中Ga、Th、F相对富集;在煤层的开采利用过程中,应重视有害元素F的综合治理及生态环境保护.
Abstract
The trace elements in coal contain rich geological and coal-forming environment information.Studying the trace elements in coal is of great significance for reconstructing the coal-forming environment,efficient and clean utilization of coal,and understanding the impact of harmful elements on people and the ecological environment.This article analyzed the geochemical characteristics and coal-forming environment of trace elements in the mineable coal seams of Changjiang coal mine.The results showed that the mineable coal seams of Changjiang coal mine formed in a shallow water and oxygen-rich environment.The relative enrichment of Ga,Th,and F was found in the mineable coal seams.In the process of mining and utilizing coal seams,attention should be paid to the comprehensive control of harmful element F and the protection of the ecological environment.
