Humbert slagheap of Ost colliery !

 

The Humbert slagheap !


Here you can see a slagheap after its completion, i.e. after that all trees, bushes etc. have been planted on it. This is one of the colliery's oldest slagheaps, named like the Humbert shaft. On a picture from 2002 Franz shaft could still be seen in the background - please click here.
