Cokerie-lavoir du Chanois
The cokerie-lavoir du Chanois is an industrial complex of the Ronchamp collieries that combines coal sorting-screening, washing, and preparation: facilities on a site adjacent to the Chanois pit, in Magny-Danigon, Haute-Saône, in the French region of Bourgogne-Franche-Comté. The sorting-washing-screening workshops were built in 1898, replacing the small workshops at the Magny shaft.
