To solve the problems in policy making, scientific research, personnel training and publicity when it comes to mine water reutilization in China, restrictive factors of the utilization of mine water resources are analyzed based on summarizing the current situation of mine water utilization rate, utilization mode and utilization price of 53 coal mines across the country. Suggestions including introducing implementable policies, improving training innovative personnel, reutilizing mine water with distinguished qualities and classes, increasing publicity and letting the guilds play their roles are raised. It is pointed out that exploiting high-quality mine water resources, utilizing thermal energy from mine water, industrialization and reutilizing mine water in abandoned coal mines should be the prospect of mine water thermal reutilization.
