| Abstract | About 600 000 cubic meters of water are daily pumped out from coal mines in USCB. The temperature of that water is always higher tha 13 degC. Thermal energy resources in mine waters are large, however not utilised. For proper estimation of these resources one have to consider aspects of mining activity which causes cooling of rock surrounding the mine workings as well as mine waters. The paper presents evaluation of geothermal energy resources in waters pumped out from 15 selected coal and ore mines. Most of these mines are abandoned. The dewatering systems have been taken under consideration in the evaluation. Total resources of geothermal energy in selected mines amount to 83 MWt and they may be economically utilised. |
