The Courrières mine disaster, Europe's worst mining accident, caused the death of 1,099 miners in Northern France on 10 March 1906. This disaster was surpassed only by the Benxihu Colliery accident in China on 26 April 1942, which killed 1,549 miners. A coaldust explosion, the cause of which is not known with certainty, devastated a coal mine operated by the "Compagnie des mines de houille de Courrières". Victims lived nearby in the villages of Méricourt (404 people killed), Sallaumines (304 killed), Billy-Montigny (114 people killed), and Noyelles-sous-Lens (102 people killed). The mine was 2 km (1 mi) to the east of Lens, in the Pas-de-Calais département" (about 220 km, or 140 miles, north of Paris).
