The collection comprises photographic half plate black & white negative and 35mm colour transparency copies of plans of mine workings for haematite, gypsum, limestone, baryte and metalliferous minerals for Cumbria dating from 1872 onwards. The plans were originally deposited in compliance with the Coal and Metalliferous Mines Regulation acts. The original plans are currently held by Cumbria County Record Office on behalf of the Health & Safety Executive (HSE) and total about 1240 plans. No digital index is available but a paper catalogue is provided by the Health & Safety Executive. As the collection relates to plans of mines abandoned after the 1872 Act, the holdings are fairly complete after this date. Note however, that the Metalliferous Mines Act originally applied only to mines employing more than 12 men, (eg. some limestone mines). Coal Authority may hold non-coal mine plans not covered by Mine Abandonment Plan collection.
