为快速、精准识别中煤华晋王家岭矿矿井充水水源，有效预防矿井水害事故的发生，分别对地表水、第四系松散层水、煤系含水层水、奥灰水、采空区积水等5种水源，进行了水化学特征、碳、氧同位素分析，讨论了五者之间的离子来源及相互联系。结果表明，采空区积水多以煤系含水层水补给，基本不受奥灰水的影响；地表水与第四系松散层水之间存在相互补给现象。研究成果为周边相似地质条件矿井水害防治提供理论依据。

 In order to quickly and accurately identify the mine water filling source of Wangjialing Coal Mine in China Coal Huajin, and effectively prevent the occurrence of mine water disaster accidents, the hydrochemical characteristics analysis, carbon and oxygen isotope analysis were carried out for five kinds of water sources, including surface water, quaternary loose layer water, coal aquifer water, Ordovician limestone water and goaf water. The ion sources and interrelations between them were discussed. The results showed that the accumulated water in goaf was mostly recharged by coal measures aquifer water, which was basically not affected by Ordovician limestone water. There was a mutual recharge between surface water and Quaternary loose layer water. The research results provided a theoretical basis for the mine water disasters prevention and control under similar geological conditions.
