Bully was so destitute that the victorious French proved unable to levy a tax on its inhabitants. In 1648, the village billeted troops involved in the Battle of Lens. From 1709 to 1712, Bully was buffeted by the advances and retreats of armies fighting in the War of the Spanish Succession, a situation aggravated by an epidemic that killed 24 villagers. In 1796, a fire destroyed half the village, an event commemorated by the present-day "Chemin brûlé." Coal mining In 1852 the first site explored by the Compagnie des mines de Béthune was near the village of Bully. The land was poorly wooded, so the company had to bring timber and workers from Cambrai. On 17 February 1852 the drill hole reached coal at . Sinking of Mine 1 at Bully began on 26 March 1852, and the mine came into operation in 1853. In 1853 7,000 tons of coal were extracted. This rose to 21,000 tons the next year.

Decrees of 29 August 1863 and 8 March 1865 authorized the Mines de Béthune to extend their railway network to Béthune and Lille. A limited company named the Compagnie du Chemin de fer de Lille à Béthune et à Bully-Grenay was formed on 11 May 1865 to operate the railway. In 1865 a more modern engine was installed in Mine 1 with two horizontal cylinders. In 1868 the Davaine ventilator in Mine 2 was no longer adequate and had to be replaced. By 1880 Mine 2 had produced 720,000 tons in total and was deep. In November 1869 eighteen workers were asphyxiated by fumes from a fire. Mine 1 was completely renovated in 1876, with a new engine installed. By 1880 Mine 1 had produced a total of 1,280,000 tons of coal, and had reached a depth of .
