Posouzení vlivu důlních vod z ložisek uranu na lokalitě Rožná a Olší na hydrosféru životního prostředí

Abstract

In this paper the influence of mine waters on hydrosphere in the area near Rožná and Olší deposits is evaluated. Influences are being discussed on the surrounding mining site Rožná and closed mine Olší. Differences in the concentration of iron and uranium compounds in time are clearly visible. RTG diffraction was done to determine the composition of the pelitic fraction. The PHREEQC Geochemical Program was used to model the saturation indexes of which it was possible to determine the precipitation probability of most possible mineral phases. Diagrams from Geochemist Work bench were used to determine the source type of mine water on deposits. Long term monitoring data shows evolution trends of mine waters in time.
