Abstract：

In most region of southwest of Shandong province,the content of fluorine in shallow- bed groundwater is high.The maximum content is 6 .0 7mg/ L .According to data derived from the hydrogeochemical survey of the shallow- bed groundwater in Juye,Yuncheng,Jiaxiang during the exploration of Juye coalfield,taking into accountthe factors of topography,geomorphology, climate,lithology,the hydrogeochemical characteristic and the mechanism of genesis of the high fluorine shallow- bed groundwater was studied.It was pointed out that the enrichment of fluorine in shallow- bed groundwater have a close relation with p H,salinity and concentration of HCO3- ,Ca2 + ,Mg2 + ,and the com ponent concentration of Ca,Mg,F and the saturation index of som e solid phases,such as Calcite,Aragonite,Anhydrite,Fluorite.The precaution and harnessing measure were put forward.
