Ibbenbüren Mine Water Drainage Tunnel – Project Presentation and Experience After 24 Months

In October 2021, construction work began on the new mine water drainage tunnel (MWDT) in the area of Germany’s northernmost coal mine in Ibbenbüren, which was closed in 2018. The costly pumps of the mine water drainage system have now been switched off and the mine water is to rise to a height of +63 m NHN (= meters above standard zero) and then be discharged via the new drainage tunnel to the mine water treatment plant at the Gravenhorst site, which is also to be newly constructed. This article presents the project task and reports on the status of the planning and construction work after a construction period of 24 months.
