摘要
贵州省兴仁县煤矿区水体水质的分析结果表明,矿山水、地下水、河水水质类型分别为[S]CaⅡ型、[C]CaⅠ型、[S][C]CaⅠ型。矿山水具有高矿化度、高硬度、高电导率、低pH值的特征。而地下水和河水具有矿化度偏高、总硬度中等的水化学特征。煤矿开采过程中对研究区地表水的水质有较大的影响,矿山水水体中的Fe、Mn、Al含量明显超标,水化学演化受控于矿业活动和地质背景条件。
Based on the analysis of water from high arsenic coal area in Xingren County, Guizhou Province,it is concluded that the quality types of refine water, groundwater and stream water are [S]Ca Ⅱ type, [C]Ca Ⅰ type, and[S][C]Ca Ⅰ type, respectively. High total ionic concentrations,high total hardness, high EC and lower pH were found in mine water. The chemical characteristics of medium total hardness and total ionic concentrations are shown in the groundwater and stream water. The surface water quality is badly affected during coalmine activity and Fe, Mn and Al concentrations are higher than those of standards. Hydro-chemical evolution of water is controlled by mining activity and geological background.
