The forty-meter-high coke mixing plant was put into use in the 1980s and has a diameter of 88 meters. After the closure of the coal mine, it was preserved and reused as a Gartendom during the 1999 State Garden Show. Since then it has not been given a new destination .
The rest of the coal mine was almost completely razed to the ground after its closure in 1992. Only the shaft and the access and administration buildings were preserved.
