Ronchamp coal mines adit

In 1997, the historical mining circuit of the outcrops was created and the exit of the channel was included as a point of interest, together with a more recent dewatering adit.

[1] As the mines were inundated with water and had to be drained, the large drainage channel was dug by the operators from east to west to perform this function, making the extraction work easier and more energy-intensive.

[3] It follows a path that crosses the hamlet of La Houillère from east to west, starting under the Chevanel hill, just below the site of the future shaft n°3 on the Champagney[3] territory.

[3][Images 4] At the end of 2012, the commune of Ronchamp undertook restoration work on the south side of the municipal landfill, which had been converted into a civic amenity site, to bring it up to standard.

The people in charge of the work and the members of the Mining Museum Association discovered on the site the remains of mine pipes[Images 5] and an old adit that had been flooded[Images 6] when the land was excavated and that was connected to the outlet of the large drainage channel.

After dewatering and draining the mine water, the adit was renovated in the spring of 2013 to make a few meters of it accessible.
