Decize coal mine

The Decize coal mine was a major historic coal-mining operation in the Decize-La Machine coal basin in the Nièvre department of France. Although the mine is associated with the town of Decize, its principal workings and industrial infrastructure were concentrated at La Machine, north of Decize. Coal extraction in the area developed over many centuries, initially through shallow forest workings that supplied local forges and other users. The earliest documented commercial evidence dates to 1488, while the name La Machine recalls a horse-powered winding mechanism, or baritel, installed in 1689 by engineers and miners from Liège. Early exploitation was fragmented among local ecclesiastical and seigneurial landowners. Small surface pits, known locally as crots, were dug in woodland, and coal was moved by animal transport toward the Loire at Decize. Attempts to organize and mechanize the workings increased during the seventeenth and eighteenth centuries. New leases, imported mining expertise, pumps, winding equipment, and eventually steam power were introduced, but ownership changes, war, financial difficulties, and the political upheaval of the French Revolution repeatedly disrupted development. By the beginning of the nineteenth century, the operation had several shafts and was producing on an industrial scale. A more durable corporate phase began in 1816 with the creation of the Société anonyme des mines de houille de Decize. The company expanded underground workings, installed steam engines, improved transport, and connected the mine more closely with the Loire and regional industrial customers. Production reached approximately 40,000 tonnes in 1842, placing the mine among France’s larger coal operations at that time. La Machine became an industrial settlement with company housing, barracks, transport infrastructure, and a workforce whose economic influence extended well beyond the mine itself. In 1869, Schneider et Cie acquired the Decize concession as part of its effort to secure fuel for the Le Creusot iron and steel works. Under Schneider ownership, the mine benefited from substantial industrial and financial resources. Output rose above 150,000 tonnes per year, and much of the coal was consumed by the Schneider industrial complex. The company also shaped the surrounding town by building roads, schools, churches, workers’ estates, rail facilities, workshops, and other infrastructure. Mining communities including Sainte-Marie, Sainte-Eudoxie, Les Zagots, and Les Minimes reflected the company’s paternalistic approach to labor and housing. The operation’s history also included serious industrial hazards. On 18 February 1890, a coal-dust explosion at the Marguerite shaft spread through connected galleries and ventilation routes, killing 43 people. It remains the deadliest accident associated with the basin. During the Second World War, Schneider management maintained formal labor categories and working-time distinctions, illustrating the regimented conditions of wartime production. The mine was nationalized on 28 June 1946 as part of France’s postwar reorganization of the coal industry. It was transferred to Charbonnages de France and integrated with the Blanzy coal mines. Nationalization brought miners stronger social protections, healthcare, paid leave, and earlier retirement provisions, but the Decize operation lost the industrial connection to Le Creusot that had previously supported its output. Mechanization and infrastructure investment continued into the 1950s, yet competition from oil, natural gas, and nuclear power accelerated coal’s decline. Several pits closed in the early 1960s, and the final pit shut on 1 August 1974. Closure ended La Machine’s principal industry and caused a severe demographic and economic shock. Of approximately 800 workers, 507 retired, around 100 were transferred to Montceau-les-Mines, and others found employment elsewhere. The town lost more than half its population over the subsequent…

Coal extraction in the Decize-La Machine basin has a documented history extending back to the late fifteenth century. A 1488 contract records surface extraction, while earlier activity may have involved informal recovery of coal from woodland outcrops. The basin’s coal was initially used by local forges and transported over short distances. Landholding was divided among the Dukes of Nevers, religious institutions, and local seigneurial authorities, which allowed charcoal burners and other operators to work numerous small pits. In 1689, the settlement later known as La Machine acquired its distinctive name after the installation of a baritel, a horse-powered winding machine. The device was installed by workers from Liège associated with the engineering tradition behind the Machine de Marly at Versailles. The introduction of winding machinery, pumps, and more systematic shaft work marked an important step toward organized mining. During the seventeenth and eighteenth centuries, however, the enterprise remained unstable. Leases changed hands, entrepreneurs struggled to make the workings profitable, and war and political upheaval repeatedly interrupted production. A steam engine was installed in 1782, but the operation was abandoned after financial difficulties. The French Revolution led to the sequestration of the mine and a period of state control before it was returned to private management. By 1801, the mine had eight shafts reaching about 80 metres and was producing approximately 8,000 tonnes annually. The creation of the Société anonyme des mines de houille de Decize in 1816 brought a more formal corporate structure. Steam engines, mine lamps, rolling equipment, and improved transport enabled output to expand. Employment and settlement grew alongside production: in 1835 the company employed 56 people directly, while the wider dependent population was estimated at more than 1,700. Coal moved toward the Loire at Decize, from where it supplied French arsenals and local industrial users. La Machine also developed an unusual horse-drawn railway system using dry locks or wagon elevators. Counterweights allowed descending loaded wagons to raise empty wagons, reducing the need for external power. This system was replaced by steam locomotives and a conventional sloping railway in 1873. Industrial demand increased after 1860, especially from iron and steel production. In 1869, Schneider et Cie acquired the approximately 8,000-hectare concession. The company’s Le Creusot works required large quantities of coal for blast furnaces, making the Decize mine part of a vertically connected industrial system. Under Schneider control, output rose above 150,000 tonnes annually. The company modernized equipment and built an extensive industrial and social environment around the mine, including roads, rail yards, workshops, schools, religious buildings, locks, forges, and housing estates. The Sainte-Marie estate was built in 1856–1857, Sainte-Eudoxie in 1878, Les Zagots in 1917–1918, and Les Minimes between 1922 and 1938. The Schneider period was also marked by a major disaster. On 18 February 1890, two blasts at the Marguerite shaft were fired too close together. The first disturbed coal dust, and the second ignited it. Fire and combustion products moved rapidly through the galleries, while ventilation links carried poisonous gases toward the Zagots workings. Forty-three miners died, including men who initially survived the blast but later succumbed to burns or asphyxiation. The accident was the basin’s worst mining catastrophe. After the Second World War, the French government nationalized the coal industry. The Decize mines were transferred to Charbonnages de France on 28 June 1946 and incorporated into the Blanzy coal mines. Nationalization improved miners’ social provisions, including healthcare, paid leave, retirement arrangements, and broader employment protections. At the same time, the Decize operation became a smaller satellite of Blanzy and was no longer supported by the direct fuel relationship with Le Creusot. Mechanization and infrastructure investment continued until about 1957, but the national energy system was moving away from coal. The Henri-Paul and Zagots pits closed in the early 1960s, production declined to a small fraction of French output, and the final pit closed on 1 August 1974. The closure produced a profound local crisis. Of roughly 800 workers, 507 retired, about 100 moved to employment at Montceau-les-Mines, and the rest sought work elsewhere. La Machine lost its dominant employer and more than half of its population over time. Preservation began before closure: former miners founded the Association Machinoise pour la Conservation du Souvenir Minier on 3 May 1970. The association helped save the Glénons pit from demolition, preserve mining machinery and documents, and collect oral testimony. The preserved headframe, shaft station, winding-engine building, miners’ school, slag heaps, housing, rail infrastructure, and industrial ruins now form a dispersed mining landscape. The Museum of the Mine of La Machine, opened in 1983, keeps this history accessible to the public.
