根据巨野煤因勘探期间巨野、郓城、嘉祥等地浅层地下水 (埋深小于 2 0m)水文地球化学的调查资料 ,结合本区地形、地貌、气候、岩性等因素 ,分析了浅层地下水的水文地球化学特征 ,对该区高氟地下水的成因有了初步认识。指出本区地下水氟的富集主要与pH值、矿化度、HCO-3 、Ca2 +、Mg2 +含量有关 ,计算了F、Ca、Mg三种元素的组分浓度以及几种固相沉积物的饱和指数 ,并提出了相应的预防和治理措施
According to the survey data of Juye coal due to the investigation of hydrogeochemistry of shallow groundwater (buried depth less than 20 m) in Juye, Yuncheng and Jiaxiang during the exploration period, combined with the topography, geomorphology, climate and lithology in this area, The hydrogeochemical characteristics of the groundwater have a preliminary understanding of the causes of the high-fluorine groundwater in this area. It is pointed out that the concentration of fluoride in groundwater in this area is mainly related to pH, salinity, HCO-3, Ca2 + and Mg2 + contents. The concentrations of F, Ca, Mg and the concentrations of three solid- Saturation index, and put forward the corresponding prevention and control measures
