This layer of the map based index (GeoIndex) shows the location and name of active mineral workings in the UK and is derived from the BGS BritPits (British Pits) database. The BritPits database of onshore mineral workings in the UK is based on the records of the BGS, the Coal Authority, industry sources and the Valuation Office Agency (Minerals) and is maintained by the BGS Onshore Minerals and Energy Resources Programme. The database describes individual workings, both currently active and formerly worked, in terms of name, location (including Mineral Planning Authority), ownership, basic geology, commodity produced and end-uses. Contact details including the operator name, address, postcode and telephone and fax numbers are held where known. The location of over 6000 workings are held, with about 2000 currently being worked. The data can be produced digitally, under licence, in formats to meet customer requirements, such as locations of workings or operator addresses, and is suitable for use in GIS applications using the British National Grid. Although the GeoIndex is updated at regular intervals more information may be available than is shown at any one time.

The map shows the location and names of boreholes with digital geophysical logs acquired by the former National Coal Board and British Coal during their exploration for coal in the UK. Ownership of UK coal exploration data was transferred to the Coal Authority (Coal Authority) following privatisation of the UK coal industry. The Coal Authority have appointed the British Geological Survey as custodian of this important national geological data archive. These data are in general publicly available; however, access to data within active mining licences is restricted in that it requires the consent of the mining licensee. The Coal Authority data archive includes digital data for some of the geophysical borehole logging. These are mainly in the form of original field tapes; however, also available are some data transcribed onto more modern media during BGS projects. The BGS will be pleased to provide information on data availability for named boreholes or within specified geographic areas, together with cost estimates and options for supplying copies.
