矿井水是煤炭开采过程中的副产品，数量巨大（仅在中国，2016年约为7.0 x 10（10）m（3））。针对不同成分的矿井水，采用了不同的水处理方法。综述了我国矿井水处理方法的应用情况、技术特点、经济性、工程适用范围等，探讨了矿井水处理技术的发展趋势，并给出了矿井水处理后的主要用途。电渗析法虽然容易结垢，但在工程应用中对水的预处理要求较高。近年来，对于我国高矿化度矿井水的处理，已逐渐被反渗透所取代。随着环保要求的提高和水资源的紧缺，技术的集成和优化将是煤矿水处理技术发展的重要趋势。
Mine water is a by-product of the process of coal mining, which is a huge amount (about 7.0 x 10(10) m(3) in 2016 only in China). For coal mine water including different ingredients, the different water treatment methods have been used. In China, utilization of the treatment methods is summarized, which presents the application situation, technical characteristics, economy, project place and etc. The development trend of mine water treatment technology is discussed, and the main uses of the treated mine water are given. On the whole, electrodialysis is easy to scale, but it requires high pretreatment of water in the engineering cases. In recent years, for the treatment of high salinity mine water in China, it has been gradually replaced by reverse osmosis. With environmental protection requirements and shortage of water resources, integration and optimization of technology will be an important trend in the development of coal mine water treatment technology.
