Interpretacja wyników pomiarów z poziomu wodonośnego objętego drenażem górniczym na przykładzie analizy obserwacji z sieci monitoringowej KGHM Polska Miedź S.A. wykonanych podczas odwadniania szybu GG-1

The article presents an analysis of measurements from the groundwater monitoring network of KGHM Polska Miedź S.A. which were taken during the dewatering of the GG-1 shaft, after water inflow from the Main Dolomite aquifer. Measurements from the dewatered shaft and piezometers were interpreted using methods designed for pumping test in Aquifer Test Pro v. 10.0 software. Based on the analysis of measurement data from a longer period of time than the dewatering itself, a systematic decrease in the water table in the observed aquifer was found, which is caused by mining drainage of the resources of the described aquifer. In order to eliminate the influence of mine drainage on the positon of water table in the analysed piezometers, trend lines of changes in the position of the water level in the observed aquifer was determined. On this basis, the magnitude of the drawdown measured in the observation boreholes was corrected before calculations were made using selected analytical methods.
