The area of influence of groundwater pumping: determination by geostatistical method in a case study
In opencast mines the mining activity often proceeds below the original piezometric surface of the aquifer in the area. Massive dewatering operations from the aquifer are resorted to in order to lower the piezometric surface and thus to prevent flooding of the working places. The influence of pumping ususally extends beyond the mining limit. To determine the extent of influence, it is suggested here to apply the geostatistical method: the semi-variograms of the drawdown levels. A case study using this method is presented and the variation of the area of influence with pumping is shown. An empirical relationship between the area of influence and the cumulative quantity of water pumped has been obtained for the mine.
