The statistical - bilance method of predicting open-pit mine flooding processes Authors: K. Polak, J. Klich
This paper presents one method of forecasting fl ooding in open-cast mines, the Statistical Balance Method. This method – using the equation of water balance discharge – was processed using data from the initial fl ooding period of the (post-mining) open-pit “Pątnów”, in the Poznan region of Poland. The parameters of this equation were determined using multiple regression. The quality of the prognostic model was estimated ex ante based on statistical values. The next step involved ex post verifi cation of the model, conducted by comparing the original forecast data to the results of the monitoring of the consequent fl ooding of the open-pit mine over a period of 18 months. The updated prognosis of the fl ooding of the “Pątnów” reservoir as well as the data concerning the subsequent and actual fl ooding of the reservoir is hereby presented.
