| 摘 要： | 煤矿矿井水中的重金属元素Cr对人体和环境具有危害。以徐州-大屯矿区为研究对象,采用淋滤模拟实验等方法,对煤层及其顶底板岩石中Cr的溶出行为及矿井水Cr污染潜势进行了研究.结果表明,煤层顶板渗透水中Cr的质量分数远高于煤浸泡水中其质量分数,表明顶底板岩石具有更高的Cr污染潜势;矿井水中Cr主要来源于煤层顶底板中伊利石向高岭石的转化;环境pH值对矿井水中Cr的含量起到控制作用,pH值、Eh值及温度对Cr的溶出行为产生影响.Cr的溶出量在中性条件下较小,在酸性或碱性条件下比中性条件下高出一个数量级以上。较高的环境Eh值和环境温度将加速Cr的溶出.

| Abstract: | Chromium (a trace heavy metal element) in coal mine water is harmful to human health and environment.The dissolvable behavior of the chromium from the coal seams and roof/floor rocks and the pollution potential to the coal mine water were investigated by a leaching experiment taking the Xuzhou-Datun coal mine district,Jiangsu,China,as a case.The results show that the chromium concentration in the leachate from the roof and floor rocks was much higher than that from the coal seams,which indicates that the ro... |
