Hydrochemické modelování mísení přítoků vod do dolů Ostravsko-karvinského revíru

Abstract

This thesis deals with mixing models of inflows of individual water sources into old mines in the Ostrava sub-basin and the Petrvlad sub-basin. These models are created for the period after the closure of the mines, thanks to which the percentage shares of inflows of individual water sources into the mine shafts were determined. In the period after the closure of the mines in the Ostrava sub-basin, the old water and water from the Bludovice pothole dominate, while the minimum share of water inflows from sandy layers of Lower Baden sediments is. Other models were created for the period of dynamic mining water pumping in the Ostrava sub-basin and the Petrvlad sub-basin. Based on the models created for the Ostrava sub-basin, it was found that the percentage shares of inflows changed and this was also associated with a change in the chemical composition of the mine waters. Mine waters were also modeled for various oxidation and reduction conditions, where it was found that due to their different chemical composition, mine waters will be saturated with different minerals under different conditions.
