Properties of reclaimed post mining catchments and its effect of run of chemistry
Hurychová, Renata ; Přikryl, Ivo (advisor) ; Rojík, Petr (referee)
After the end of hydric recultivation from the monitored source of watering, artificially bulit-up lakes are fed with the water from their own basin. This water is not so systematically monitored as compared to the water from the new lake and the sources of its filling. This thesis summarizes findings about the developement of artificially made basin in the mining area and explains differences between various basins. Further, this work deals with the characteristics of water feeding lake "Chabarovicke jezero (Milada)", which was bulit-up during hydric recultivation of the mineshaft in the soft-coal quarry Chabarovice. Monitored basins have different area, slope, vegetation coverage and distribution of dissolved compounds. These factors have significant impact on the character of the water in affluents. We found out, that affluents from the own basin have high concentration of dissolved compounds resulting in the unwanted enrichment of the lake. Big problem was the high concentration of sulphates and nitrates, which in all affluents, except for one, exceed tolerated limits for surface waters. In the course of time, concentrations of dissolved compounds go down. Particular affluents differ between each other and the main impact on the water characteristic is the slope, exposition and area. In the...

Effecto of surface winning on the freshwater quality
Hurychová, Renata ; Přikryl, Ivo (advisor) ; Benešová, Libuše (referee)
The aim of this work is to show, how much different is the flowing mine water and water, which was not affected by surface mining. The literature on this theme was collected and evaluated. The question was studied in the experimental project, which covered examination of mine landscape water in Sokolovsko. In this research, 17 samples of different flowing water were taken and following values were determined: pH, conductivity, acidity, alkality, hardness, content of nitrates and nitrites, amonnium ions, phosphates, iron, chloride, calcium and manganese ions. These data were compared between samples from sites with different degrees of mining extension. The measured values were compared with previously published values from other sites.
