| 摘 要： | 选择山西省西山煤电股份有限公司马兰煤矿和大同煤矿集团公司四台煤矿为研究区，利用IC，ICP—MS，XRD，XRF和粒度分析仪等分析测试仪器，并结合水文地球化学模拟软件PHREEQCI，对酸性矿井水及其沉积物的地球化学性质进行了详细分析．研究结果表明，酸性矿井水具有较低的pH，较高的Fe和SO4^-浓度，并含有多种重金属元素；PHREEQCI软件模拟计算发现酸性矿井水中金属的结合形态主要为Me^n＋和MeSO4^n-2；酸性矿井水沉淀物的矿物组成主要受酸性矿井水的pH，Fe和SO4^2-浓度的控制，并以针铁矿等含铁矿物为主，在国内首次发现了Schwertmannite矿物。

| Abstract: | In this study,geochemical characteristics of acid mine drainage(AMD) and their sediments from the Malan and Sitai coalmines,Shanxi Province,China,were investigated using IC,ICP-MS,XRD,XRF,and PHREEQCI modeling calculation software of hydrogeochemistry.The results show that AMD is characterized by higher concentration of iron and sulfate,a lower pH,and a wide variety of heavy metals.The results of modeling calculation by PHREEQCI software demonstrate the metals in AMD are present mainly as Men+ and MeSOn-2 4species.The sediments of AMD are mainly composed of iron-bearing minerals such as goethite and schwertmannite,which are controlled by pH,Fe and SO2-4concentration.The schwertmannite mineral was found firstly in China. |
