摘  要:为揭示淮北煤田宿东矿区塌陷塘周边地下水水化学特征及影响因素,查明离子来源,明晰水质情况,采集了36个地下水样品。采用数理统计分析和水化学图解法,对研究区地下水的主要离子来源进行分析;运用综合水质指数(WQI)和Wilcox图解法对研究区浅层地下水进行适用性水质评价。结果表明:研究区地下水属于淡水,呈弱碱性,水化学类型以Na-HCO3为主。水化学特征以受岩石风化作用控制为主。WQI评价结果表明,68.75%的水样水质较好。Wilcox图解法评价结果表明研究区地下水均可直接作为灌溉水使用,且合理利用不会使土壤盐碱化。In order to reveal the hydrochemical characteristics and influencing factors of the groundwater in the launch of the Huaibei Coalfield Sudong Mining Area, find out the ionic sources, determine the water quality, 36 groundwater samples were collected. Mathematical statistical analysis and hydraulic diagram method were used to analyze sources of groundwater ions. The comprehensive water quality index (WQI) and Wilcox illustration method were used to evaluate the water quality in the research area. The results show that the groundwater in the research area is freshwater, which is weakly alkaline, and the type of hydrophobic chemistry is mainly Na-HCO3. Hydrogenic characteristics are mainly controlled by rock weathering. The results of the WQI show the quality of 68.75% samples are better. The results of irrigation water quality evaluation show that the surface water samples of the research area can be used directly as irrigation water, and the reasonable use of soil will not make soil saline.
