Mine water is a valuable unconventional water resource. According to the discharge of mine water and the factors of geographical location, climate, geological structure, mining depth and mining method, this paper analyzes the spatial distribution and treatment process of clean, containing suspended solids, high salinity, acid and special pollution mine water in China. Based on the instability of mine water inflow, the complexity of water quality in different mining areas and the difference of treatment process, the risk factors of water quantity, water quality and economy (treatment cost and irrigation benefit) of mine water farmland irrigation were analyzed. The risk prevention and control strategy of mine water farmland irrigation is put forward, which is of great significance to ensure food security.
