Specific Design of Flooding Monitoring of the Rožná I Uranium Mine, Czech Republic

Popis výsledku v původním jazyce

In the past, the beginning of the decline in mining activity in the early 1990s led to the termination of activities in many localities. The article deals with the issue of flooding the last uranium mine in Central Europe, where uranium ore was mined until 2017. The situation is specific due to the form of two-stage flooding of the mine. The first stage of flooding was started at the beginning of 2021, and the whole process will be completed after reaching the 13th mine level, where pumping will be resumed. This situation makes it possible to support the forecasting of flooding in this locality and to refine the model of the second stage of flooding and the area of post-mining activities. The article proposes continuous monitoring of the level of mine water onset, namely in shafts R7S and R3. Measurements on the shafts spaced about 3 km apart will allow additional comparison of the measured data of the level increase rate due to the documented extracted free spaces of the deposit and systematic measurement of groundwater inflows into the deposit. Another comparative criterion will be the periodic mine water sampling for the measurement of physico-chemical parameters. It offers the possibility of extending monitoring with other options, such as continuous measurement of hydrochemical parameters using all-solid-state sensors designed for harsh mining conditions or the use of autonomous UNEXMIN underwater drones.
