This paper addresses the distribution and occurrence of harmful organic substances in coal gangue dump from Jiulong Coal Mine and its influence on the environment. The samples were taken from the coal gangue dump and coal waste water stream and analyzed by organic geochemical methods. The results indicate that the coal gangues contain abundant harmful organic substances like polycyclic aromatic hydrocarbons. The TOC and sulfur contents of the samples are much higher than those of the background sample except Sample JL7. The contents of organic bulk parameters are relatively high. Ten carcinogenic PAHs were identified and these harmful organic substances have influenced the surrounding area. Along the waste water stream, organic substances pollute at least 1,800 m far from the coal gangue dump.
本文研究了九龙煤矿煤矸石堆场中有害有机物质的分布与赋存情况及其对环境的影响。样品取自煤矸石堆场和煤矸石废水流，并采用有机地球化学方法进行分析。结果表明，煤矸石中含有丰富的多环芳烃等有害有机物质。除JL7样品外，其他样品的总有机碳（TOC）和硫含量均远高于背景样品。有机总体参数含量相对较高。已鉴定出10种致癌多环芳烃，这些有害有机物质已对周边地区产生了影响。沿着废水流，有机物质对距煤矸石堆场至少1800米远的区域造成了污染。
