• open-pit closure
• prognostic calculations

The closure of native sulphur mines in the vicinity of Tarnobrzeg has reached a final stage, The open pit in Machow, isolated with 25-meters-thick clay layer, is successively filled with water from the Vistula River. In the Jeziorko borehole mine land remediation is under way and gravitational drainage system is under construction. Delay in closure operations took place in the area of the Piaseczno Mine where recreational center has been designed around a water reservoir of water table altitude 146.0 m a.s.l.
The safe closure and remediation of the Piaseczno open-pit requires the construction of drainage system in the area endangered by soaking. The current (data for the year 2006) hydrodynamic conditions and prognoses of future changes of aquatic environment possible in the post-mining land were analysed with the numerical filtration model. The results enabled the identification of the position of groundwater tables in Quaternary and Tertiary horizons along with the discharge of designed drainage systems.
