This work was created during the final days of the Kellingley Colliery in Yorkshire, which closed in December 2015, marking the end of deep-pit coal mining in Britain. In an era of cheap imports and cleaner energy alternatives, the fuel of the industrial revolution was no longer required by the domestic market. Some of the last generation of men to know the hardships of the pit posed for portraits in the days before it closed. These images now form part of the archive at the The National Coal Mining Museum in Wakefield.
