Abstract

Coal mining will damage water resources, based on the analysis of mine water resources in the western region of China. Using mine water as the medium, a coal-water-wind (solar) energy comprehensive green energy exploitation system is established. Mine water is stored in underground spaces formed by mining, and mine water purification is achieved by fractured rock and goaf. Using multistage underground reservoirs, through pumping to store energy, the unstable solar and wind energy is converted into a stable output power. The possibility of using the mine water as a medium to use the clean energy, and the prospect of the utilization of mine water resources in the future, is discussed.
