| 摘 要： | 煤矸石是煤炭采掘和洗选中排放的固体废渣，它含有As、Cr、Hg、Cd等22种有害微量元素，这些有害元素在矸石自堆放过程中，由于自然、淋滤、风化等作用而逸出，进入大气、土壤、植物和水环境。本文以兖州煤田山西组和太原组煤矸石为对象，研究了As、Cr、Hg、Cd、Pb、Cu、Zn7种有害元素在矸石及其周围土壤中的分布规律，其含量多数高于地壳克拉克值和土壤背景值，土壤中的含量随着远离距矸石而减小，因此，矸石灰尘和溶出液可污染土壤和水体。

| Abstract: | The coal gangue from coal mining and coal washing contains 22 harmful microelements such as As,Cr,Hg,Cd.Due to self-combustion,washing by rain and wheathering etc,these microelements enter into atmosphere,soil,plant and water.The distribution regularity of As,Cr,Hg,Cd,Pb,Cu,Zn etc in coal gangue from Yanzhou Coal Mine(Shanxi group and Taiyan group)and in adjacent soil is studied.The conclusion is that coal gangue ash and its solution are pullutants for soil and water. |
