中文摘要：
从淮南煤田潘谢矿区采集了不同水体（大气降水、地表河水、太原组灰岩水、奥陶系灰岩水和寒武系灰岩水）样品34个,进行溶解性总固体（TDS）,δD和δ18O的测试,分析了不同水体的氢氧同位素组成特征及其成因.结果表明：不同的蒸发斜率以及氘盈余表明潘谢矿区多个灰岩含水层的蒸发作用以及地下水滞留时间的差异.太原组灰岩水与地表水（河流）水力联系相对于奥陶系灰岩水更强,灰岩水（石炭系、奥陶系、寒武系的碳酸盐岩裂隙岩溶水）的同位素组成特征可能因为浅层水与深部地下水的混合.水岩作用等原因导致灰岩含水层表现出了不同程度的氢氧同位素漂移.
英文摘要：
34 water samples （i. e, rainfall, surface water, groundwater from the Taiyuan Formation limestone aquifer, the Ordovician limestone aquifer and the Cambrian limestone aquifer） were collected from the Panxie mining area of Huainan Coalfield,and TDS （total dissolved solids）, hydrogen and oxygen isotopes （δD and δ18O） were determined. Different evaporation slopes and deuterium excesses of individual aquifers indicate that there are different evaporation rates and residence times among them. The Taiyuan Formation limestone aquifer has a stronger hydraulic connection with the surface water compared with the Ordovician limestone aquifer. shallow recharge groundwater primary factor responsible for limestone aquifer. Isotope composition of the limestone water is associated with mixing between and a contribution including mineralized fluids from the deep aquifer. The δD and δ18O excursion may be attributed to water-rock interaction in the
