As early as 1444, coal was mined along the banks of the Sambre. At the beginning of the nineteenth century, industrialization started and the coal mine had a depth of 120 meters. The SA Charbonnage de Floreffe mined an area of about 500 hectares, there were several extraction sites (called bures). The mine in Floriffoux was also called Sainte-Barbe. The history of the mine included several takeovers and bankruptcies. There was a rail connection to Floreffe station. Built in 1911, this metal railway bridge stretched over the Sambre. In the closing year of 1924, 122 people worked in the mine. The metal bridge was demolished in 1930.
The restored concrete shaft trestle is still standing today and serves as a mobile phone mast. The offices, like the bathing room and forge, have been restored. The machine room has also been preserved. Part of the domain is now an animal shelter (Croix Bleue).
The restoration of the shaft trestle and associated buildings started in mid-2019. It has now become a beautiful domain with also "La cantine du charbonnage".
