GROUNDWATER FLOW MODELLING APPLICATIONS IN MINING HYDROGEOLOGY

摘要

In the presented paper some specific features and problems of numerical modelling applications in mining environment are briefly discussed. The issues discussed are documented by three modelling case studies. Two of the applications are aimed at mine dewatering problems in active coal mines. The first represents the underground hard coal mining region in the Czech part of the Upper Silesian Coal Basin. The second example is focused on optimisation of the dewatering regime of open pit mining of brown coal in the Most sub-basin of the North Bohemian Coal Basin. The third example describes the concepts of mathematical modelling to be applied to solving the issues of the intensive utilisation of mine waters from flooded uranium mine Olsi-Drahonin as a source of uranium with an accompanying effect of shortening the time necessary for the purification of mine waters discharged into watercourses.
