This coal mine has stopped for years, and is now preserved as monument to Industrial Architecture.
It's fantastic, especially the part where they used to make cokes. This scene.
The coal would be heated for hours to 180 degrees in the closets on the right, and then dumped into the water and transported.
It reminds me of my youth: there was a huge coalmine around the corner, literally (Staatsmijn Emma), and I still remember that I could see the same kind of cokes-furnaces from the bridge crossing the railroads on the Akerstraat.
