Lignite mine flooding in Germany faces potential delays

Experts warn that the flooding of active lignite open-cast mines, specifically Vereinigtes Schleenhain in Saxony and Profen in Saxony-Anhalt, may take longer than previously anticipated. Low river levels and declining groundwater levels are cited as primary factors that could disrupt existing plans.

Martin Kreßner, a mining reclamation expert from TU Bergakademie Freiberg, noted that a reduced water supply could lead to extended remediation periods, increased technical complexity, and higher costs. If water levels rise more slowly than planned, additional technical measures may be required to stabilize embankments. While the flooding process might be delayed, experts suggest there is no alternative to the formation of residual lakes, as groundwater will naturally rise once artificial drainage ceases.

The mining company Mibrag has stated that its fundamental planning remains intact, noting that forecasts for flooding duration are based on multi-year precipitation series.
