The possibility of disposing of selected kinds of industrial waste into abandoned mines, or into the exploited parts of active mines, belongs at present to topical problems in the Czech Republic. In the Czech part of the Lower Silesian Basin, the mining activities have stopped in 1995 and the mines are now under a process of liquidation. Mine workings in both the Odolov and Katefina Mines were simply flooded and their shafts were filled by sorted rock material. The first negative impacts on groundwater quality were documented for this method of liquidation. The Mine Jan Sverma Mine was liquidated instead by filling of the mine workings with a floated self-solidifying ash mixture. Finally the mine workings were sealed with the fill that had the hydraulic properties of impermeable rocks. All the mines considered represent independent geo-hydrodynamic systems without connection with other hydro-geological structures in the study area. The hydro-geological problems of the two liquidation methods are assessed in this contribution.
