Abstract: Reuse ways and treatment technologies are the most important factors affecting mine water reuse. Therefore, through a large number of literatures and investigations, the reuse ways and treatment technologies of mine water in major foreign mining countries are analyzed and summarized. At present, in addition to mining production reuse, foreign mine water reuse ways mainly include domestic drinking, industrial uses, irrigation, environmental uses and heat supply, etc. At the same time, mine water discharge is also common. Foreign mine water treatment technologies mainly include active treatment technologies such as reverse osmosis, and passive treatment technologies such as constructed wetland. More emphasis is placed on the development and application of passive treatment technologies with low energy consumption and low maintenance. In addition, foreign developed countries also generally pay attention to mine water classification collection, and the treatment of abandoned mine drainage, etc. The research on the current situation of foreign countries can provide a higher learning significance for the mine water reuse in China.
