User guide : BGS Mining Hazard (not including coal) GB version 9

The BGS Mining Hazard (not including coal) GB dataset summarises the location and extent with an indication of the level of hazard associated with former and present underground mine workings.
The dataset covers Great Britain and is published at 1:50 000 scale. The content is derived from a range of data sources including, but not limited to the bedrock geology, extensive literature reviews of both published and unpublished documents, abandonment and mine plans, combined with a wealth of expert knowledge and experience.
The release of Mining Hazard (not including coal) version 9 builds on the content of previously published versions. The coverage has been expanded with the inclusion of newly identified areas and drawing on data from the BGS published BGS BritPits and other resources.
The data have been compiled and presented in an easy-to-use format to provide a national overview of the country’s mining legacy. Given the long and complex mining history of Great Britain, this dataset represents the best information available at the present time (October 2025). Work continues to develop this product, which will result in the release of ad hoc updates in the future.
The information provided in this User Guide is intended to provide a quick start guide to using and understanding this BGS data product.
