ABSTRACT: Abandoned mine workings can serve as the drinking water supplies in the areas of drinking water shortage after appropriate quantitative and qualitative analyses. Originally dynamic, partly by pumping artificially created regime passes into the dynamic-static reg ime of mine waters. The static reg ime of mine waters is typical for the abandoned mine workings under the local erosion leve1. During gradual inundation an intensive mixing of mine waters of individual horizons, filling the groundwater reservoir takes place, as well as intensive redox changes causing the result chemistry changes of the mine waters static supplies. The mentioned waters are not suitable for utilisation due to higher total mineralization. Chemistry is not changing at all and it is stabilised usually in the mine workings situated above the erosion leve1 where the gravity mine drainage occurs. Chemistry indicators of mine waters fulfil STN 75 711 Slovak drinking water standards on the veins with characteristic carbonate-sulphide mineralization. These mine waters, are presently utilised as the drinking water supplies.
