The collection contains records generated and received by the Wearmouth Coal Company Ltd solely in connection with deputations made by the Monkwearmouth Lodge of the Durham Miners' Association. They describe in detail complaints and grievances made by members of the lodge. Although the records do not provide details about the constitutional history, financial position or production methods of the company, they illustrate labour relations in the coal industry and the operational procedures undertaken by miners at the time. The records in the collection cover a period containing the depression years of the late 1920s and early 1930s, the second world war and the run up to nationalisation of the industry in 1947.
The collection consists of volumes of deputations made by the Monkwearmouth Lodge of the Durham Miners' Association and minutes of meetings where representatives of the company and the lodge were present, describing in detail complaints and grievances made by members of the lodge, November 1925-December 1946.
