In December 2002 the 25-meters-thick protection layer has been completed which sealed the bottom of the future reservoir from the polluted waters in Tertiary formations. Until the reservoir is filled with water from the Vistula River it will be drained in order to avoid the unsealing of protection layer. The mathematical model of hydrogeological conditions in the Tarnobrzeg Sulphur District and the MODFLOW software were applied to prognosing the changes in aquatic environment at the final stage of Machów open pit remediation. The results of calculations enable the optimization of draining wells location and the volume of drained Tertiary waters as well as the prediction of environmental impact of the mine closure. The modelling revealed that during the flooding of the pit the volume of waters drained from the Tertiary horizon can be substantially limited until the final closure of draining system. The new, important draining center for polluted waters from Tertiary horizon will become the unremediated open pit of the Piaseczno Sulphur Mine.}, type={Artykuł}, title={Hydrogeological prognoses for the closure of the "Machów" native sulphur mine}, URL={http://ochroma.man.poznan.pl/Content/132551/PDF/6_GSM_19_3_2003_Haladus_Prognozy.pdf}, keywords={hydrogeology, mine closure, prognostic calculations}, }
