摘　　要：为了研究深层地下水的地球化学特征,从淮南煤田潘北矿区系统采集了不同水体(地表水、太灰水、奥灰水和寒灰水)样品25件,进行δD、δ^(18)O和常规水化学的测试,分析不同水体的水质化学特征以及氢氧同位素组成特征,结合同位素与常规离子的关系特征,探讨太灰水与其他水系之间的联系。结果表明:太灰水主要表现为三种水质化学类型,太灰水的氢氧同位素含量差别较大,太灰水的主要补给源为地表水体和深部古水。To study the geochemical characteristics of deep groundwater,25 samples of different water bodies(surface water,groundwater from the Taiyuan Formation limestone,Ordovician limestone and Cambrian limestone aquifers)were collected from the Panbei mining area of the Huainan coal field to carry outδD,δ^(18) O and conventional hydrochemical tests,for analyzing the chemical characteristics of water quality and hydrogen and oxygen isotope composition of different water bodies,and studying the relationship between the groundwater from the Taiyuan Formation limestone aquifer and other water systems,with the relationship between isotopes and conventional ions being taken into consideration.The results show that there are three chemical types of water quality for the Taiyuan Formation limestone aquifer,in which hydrogen and oxygen isotope contents differ greatly,and the water is mainly replenished from surface water and deep ancient water.
