Coal mining

Vermelles was the second extraction site used by the Compagnie des mines de Béthune. Excavation of Mine 3 in Vermelles began in January 1857, reaching a rugged, steeply inclined deposit of coal at 147 m. Extraction started in July 1860. Air compressors were installed in Mine 3 1877. This proved the company's most productive mine, with a total of 1,525,000 tons. Excavation of Mine 4 at Vermelles started in October 1865 and reached coal at 149 m. Extraction started in 1867. Mine 4 was abandoned in 1876 because the very irregular deposit at 250 m seemed unusable. There was a lot of firedamp compared to other mines. Mine 4 was reopened and extraction resumed at 387 m in 1911. The main shaft reached 389 m. During World War I (1914–18) the Germans were stopped just to the east of Vermelles. Mine 4 was recovered in December 1914. Barricades were built as early as 1916 along the main axes of the mine complex so it could be defended while allowing ventilation and the passage of men. Mines 3 and 4 in Vermelles were isolated from the rest of the mines by watertight doors. After the war, Shaft 4bis was opened to the north of Shaft 4 in 1925 for ventilation, 301 m deep. Mine 4 was closed in 1965, and Mine 3 was closed in 1977.
