结合粉煤灰堆放场的水文地质状况，通过稳定同位素示踪、浸溶和淋溶试验，探讨了灰场对周围岩溶地下水的影响。结果表明，堆场灰水已经达到下游部分水井，堆场在大气降水和冲灰水的浸泡、淋溶作用下，其中的 Cr6＋、F -和钙镁盐类大量析出并随灰水一起下渗，石灰岩碎石虽对氟化物有一定的吸附作用，但能力有限。根据试验数据分析认为，该粉煤灰堆放场是焦作市北中部岩溶地下水 Cr6＋、F -和总硬度升高的主要原因。

Combined with the hydrological geology condition of fly ash dumping site,through stable isotope tracer,soaking and leaching experiment,the influence of fly ash dumping site on karst groundwater around the ash field was discussed.The results showed that,the ash water had reached the part wells downstream,under the soaking and leaching action of atmospheric precipitation and ash water,the Cr6 +,F -and calcium and mag-nesium salts in dumping site precipitate a lot and infiltrated with the ash water,while limestone has certain ad-sorption of fluoride.According to the experiment data,the fly ash dumping site is the main reason which cause Cr6 +,F -and total hardness to rise in Jiaozuo north middle karst groundwater.
