巨野煤田浅层高氟地下水成因分析

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

GENESIS ANALYSIS OF JUYE COALMINE SHALLOW HIGH FLUORINE GROUNDWATER

Based on he hydro-geochemical investigation data of the Juye, Yuncheng, Jiaxiang etc. shallow groundwater (bedding depth less than 20m) during the Juye coalmine exploration period, combining with the topographical, geomorphological, climatical, lithological etc. factors, the paper analyzes the hydro-geochemical characteristics of the shallow groundwater. Thence, it acquires a preliminary knowledge of the genesis of the high fluorine groundwater in the district. It points out that the fluorine concentration of groundwater in the district chiefly concerns with the pH value, minerological degree and the HCO - 3, Ca 2+ ,Mg 2+ contents. It calculates the component concentration of the three elements F, Ca, Mg, and the saturation indexes of several solid-phase sediments. Also, it presents the corresponding precaution and treatment measures.
