The Inden opencast mine of RWE Power AG is located in the Rhenish lignite mining area near Inden , between Eschweiler and Jülich . The annual production amounts to 22 million tons of lignite and serves exclusively to supply the Weisweiler power station . The coal seams are up to 45 meters thick. The excavation takes place with the help of bucket wheel excavators , the backfilling before the recultivation with settlers . 850 people are employed in this company. The open pit mine is expected to be exhausted by 2030 . The construction engineer Andreas Wagner is the head of the open pit mine .
The Inden opencast mine has lignite reserves of currently 440 million tonnes that can still be mined. The lignite originated from extensive forests and moors that developed in the Lower Rhine Bay 30 to 5 million years ago. The geology of the Lower Rhine Bay is characterized by long-lasting subsidence movements in the last 30 million years, which have led to the deposition of up to 1,300 m thick sediment in this region through the North Sea and many rivers.
history
The open-cast mine was opened in 1957 by the brown coal and briquette works Roddergrube AG . As early as 1959, around one million tons of lignite were being mined for the power plant in Weisweiler. The dismantling was postponed between 1969 and 1981 because the production in the Zukunft-West opencast mine was sufficient for its operation. With increasing charring, the mining equipment moved from there between 1981 and 1987.
Resettlement of localities
The large-scale dismantling made it necessary that some villages had to be completely abandoned and the residents relocated. In the population there was sometimes vehement resistance to this, but the resettlement is seen by the opencast mine operators as inevitable, as the coal profit from the opencast mine legally serves the public good. The Rheinbraun AG buys the land and houses of local residents in order to subsequently demolish. When the entire site is demolished, the brown coal seams will be exposed and mined.
Sometimes new localities are founded that contain the name of the old locality or name combinations such as Inden / Altdorf . The official name of Indener hamlet Inden / Altdorf with slash in Germany unique.
In the case of Inden, archaeologists are examining an entire parish with associated villages and streets for the first time in Germany - before the site is excavated . It is the parish of Geuenich with Altdorf and Inden . In contrast to the Zukunft opencast mine , where archaeological rescue excavations began too late in the parish of Lohn and were therefore “not optimal”, the investigations in Inden began in 1988, 15 years before the excavation.

Reclamation
The Inden opencast mine is moving eastwards. This means that on the eastern edge of the open pit, the layers above the coal are removed until it is exposed. The overburden that arises is then backfilled on the opposite side and the landscape is recultivated, so that the open pit quasi “wanders”. Lake Indesche is to emerge after the coal has been burnt out .
Diversion of the Inde
As the Inde River crosses the mining area, a new river bed was created that has been leading the river around the open pit to the west since the end of 2005.
