Beginning Coal deposits were discovered in Ronchamp in the mid-18th century. Mining activity was a complementary resource for a population whose main occupation was agriculture. In 1744, two exploration galleries and various surface excavations were dug, but these works were unofficial. Two concessions were finally granted in 1757, the concession of the lords of Ronchamp in Ronchamp, granted on September 11, 1757, and the concession of the
prince-abbots of
Lure in
Champagney, granted on April 21, 1757. The decree of September 24, 1768 granted the barons of Ronchamp and associates the exclusive exploitation, for a period of about thirty years, of all the coal mines that are located within the extent of the barony of Ronchamp. The two concessions became one, and they were operated at common expense by the two concessionaires, who requested a single concession. This was granted by the decree of March 1, 1763. == Mine list ==
