| Abstract | Mine waters of underground mines are characterized by steady temperature, which is considerably higher then the annual air temperature of respective locality. In addition, many of them have relatively high yield, therefore they can represent interesting low enthalpy geothermal resources. Presumed mine water heat-energetic potential in in working coal mines or abandoned ore mines in volcanic rocks occured in the territory of Slovak republic ranges in single cases from 0,7 to 7 MWt (water temperature 14-19?C), in rest of mines reaches some tenths of MWt (to 13?C). These potential low enthalpy geothermal resources aren•t used in present, but can have local meaning although heat pumpes have to be used for heat extraction. Water sources of higher temperature can be obtained by isolating suitable outflows in workings. By this way the source of thermal water (40Ül.s-1, 57?C) was caughtÜin the Kremnica mine for thermal bath supply. |
