The map shows the location of borehole records containing digital geophysical logs acquired by the former National Coal Board and British Coal during their exploration for coal in the United Kingdom.

Following the privatisation of the UK coal industry, ownership of UK coal exploration data was transferred to The Coal Authority (CA), who appointed the BGS as custodian of this important national geological data archive. In general, the data is publicly available, however, access to data within active mining licences requires the consent of the mining licensee.

The CA data archive includes digital data for some of the geophysical borehole logging. The original tapes have been transcribed and the data are available as tape image files (TIF) or, in some cases, as digital log ASCII standard (LAS) files.

We can provide information on data availability for named boreholes or those within a specified area, together with cost estimates and options for supply. To find the names of boreholes please use the GeoIndex, click on ‘Map layers’, select ‘Map Theme: GeoPhysics’ and tick on ‘British Coal Geophysical Logs’
