摘要
以淮南煤田5个矿区20个监测点采集的水样为研究对象,分析了矿井水的pH、总硬度、SO_4^(2-)、Cl^-4项指标,研究了水质特征并利用灰色聚类法对水环境进行了综合评价。研究发现,淮南煤田矿井水为碱性水,总硬度较低,SO_4^(2-)浓度为中等,Cl^-浓度变化较大。煤田矿井水环境类型差异性明显,Cl^-浓度对该区水环境影响最大。
Taking 20 collected water samples of 5 coal mining areas in Huainan coalfield as the research object, analyzes the mine water PH, total hardness, SO42-, Cl-, four index, studied the characteristic of water quality and conducted a comprehensive evaluation of water environment by using grey clustering method. The study found that the coal mine water in Huainan coal mine is the alkaline mine water, the total hardness is low, the SO42-concentration is medium, and the Cl- concentration changes relatively large. The difference of water environment type of coal mine is obvious, and the water environment of the area is affected most obviously with Cl-concentration.
