摘　　要：为缓解矿区水资源紧缺的状况,利用采空区预沉淀、水射器曝气和相互冲洗过滤装置接触氧化过滤,将哈拉沟煤矿矿井水在井下直接处理后作为井下生产用水。运行实践表明,该处理利用系统适合煤矿井下巷道环境,可有效地去除矿井水中的悬浮物(SS)、铁(Fe2+)和锰(Mn2+)等物质,总进水平均质量浓度分别为323mg/L(SS)、1.21mg/L(Fe2+)、0.28mg/L(Mn2+),总出水平均质量浓度分别为2mg/L(SS)、0.11mg/L(Fe2+)、0.04mg/L(Mn2+),相应平均去除率分别为99.4%、90.9%、85.7%,均达到煤矿井下生产用水水质要求。In order to moderate the situations of water- resource shortage in mining areas,the mine water of Halagou was treated and utilized as production water supply,with the reuse system comprising pre- precipitation of goaf,aeration of water- jetter,and contact- oxidation filtration of interacted flushing filters. The practice application showed that,the system could adapt the underground environment of coal mines,and remove suspended solids（ SS）,ferrous（ Fe^2＋） and manganese（ Mn^2＋） effectively. The average concentrations of SS,Fe^2＋ and Mn^2＋in the inflow were 323 mg / L,1. 21 mg /L and 0. 28 mg / L respectively,and those of the treated were 2mg / L,0. 11 mg / L and 0. 04 mg / L,with the average removal rates of 99. 4%,90. 9% and 85. 7%,respectively,meeting the demands of production water supply in the underground coal mines.
