Koncepce odvodňování dolu Rožná I v Dolní Rožínce

Abstract

The object of this work is describe the drainage conception of the last uranium mine in Czech Republic. At the work I focused on fully automated cascade pumping system which pumps the mine water to the mine surface, and thereby maintains the level of mine water at such level that it is possible exploit uranium ore without problems. From the perspective of water economy I describe the purification of exhausted mine water in surface decontamination stations and their following discharge into the watercourse. At the conclusion of this work I will outline the drainage conception of deposit Rozna after finishing of mining. It involves inundation of mines area where the mine water will controlled drain for cleaning using the currently driven drainage adit. After reducing of harmful substances at the permitted limit, mine water will unprompted discharged by the drainage adit into the river Nedvedicka.
