The Fourneaux shaft was dug to a depth of 130 metres by the Société des Houillères du Grand Moloy in the commune of Saint-Léger-du-Bois
It was put into operation in 1928 and then bought by the Société des Houillères et Chemins de fer d'Épinac.
The Société Minière des Schistes Bitumeux (SMSB) bought the mine in 1943 to supply its shale oil distillation plant before closing the shaft in 1950. The site was left abandoned, only the old headframe survived. The headframe will be cleared and cleaned years later by the association of Safeguard of the Industrial Heritage Epinacois and highlighted by the installation of explanatory plates.
