Houillères de Sincey
France
The Sincey coal mines were anthracite mines operating between 1835 and 1908 in Sincey-lès-Rouvray and neighboring communes in the western Côte-d'Or region. The deposit was discovered by Count Champion de Nansouty in 1835. After experiencing competition from Baronne de Candras, the two rivals' wells closed before 1842, and only the outcrops remained exploited. After 1860, activity was revived by Eugène Soyez, founder of the Compagnie des mines de l'Escarpelle in the Nord-Pas-de-Calais mining basin. The Soyez de Sincey shaft (which bears his name) was sunk in 1862 and operated industrially from 1876 to 1908. Maximum production in the coalfield was 12,000 tons a year, and total production amounted to 225,000 tons. At the beginning of the 21st century, a few ruins remain in the vegetation, as well as a few “corons”.
