Swalwell Colliery is shown on Ordnance Survey second edition map. Closed August 1940. There were two pits, Edith Pit and Henry Pit. Owners were George R. Ramsay and later Dunston Garesfield Colleries Ltd.

NEHL - The Henry Pit was opened around the 1880s at the south of the village on Miller's Lane. It was a fairly small working, utilising a few sidings from a branch leading from the Newcastle & Carlisle Railway on the riverside. It featured a drift to the south east of the site, as well as a shaft with the headgear dominating the townscape. There was no pit village of sorts, with workers utilising the pre-existing cottages with Swalwell already dominated by the paper mill and metal works on the large mill race through the settlement.

The pit had persistent issues with industrial relations. In 1909, batches of miners were imprisoned for defaulting payments having absented themselves from work, many in sympathy for the original pitmen who were sent to Durham Gaol and refused to work. The first lot totalled 124 who were all imprisoned for 7 days, and were supported in the hundreds by the local villagers.

The site is now an industrial zone, and there is no trace today.
