Contains digitised mine plan contours, spot heights and worked ground outlines on key coal seams from the Midland Valley in ASCII or ArcView format. Incomplete, only some seams and some areas digitised. All contours digitised on key seams, worked ground outlines simplified, spot heights digitised where no contours exist.

This layer of the map based index (GeoIndex) shows the locations of known mines, mineral showings and localities, including sites where minerals of economic interest have been identified in panned concentrates. The information for the index is taken from the Mineral Occurrence Database. The Mineral Occurrence Database holds information on mineral occurrences in the UK including locations of known mines, deposits, prospects and mineral showings, including sites where minerals of potential economic interest have been identified in panned concentrates. Data is normally taken from published sources or from internal BGS records, such as field sheets, rock and stream sediment collection cards. Data compilation started ca. 1994 and the database currently holds about 13 000 records, but details of many more old workings and occurrences remain to be added.

Index to various collections of Aerial Photographs purchased or obtained by BGS and its precursors as part of its surveying activities. The index was set up in 2000 and mainly covers Great Britain. The level of spatial detail depends on the flight plans provided, but most are referenced at least to OS quarter sheet level.

Dataset of mineral occurrences in the UK including locations of known mines, mineral showings and localities, including sites where minerals of economic interest have been identified in panned concentrates. Data is normally taken from published sources or from internal BGS records, such as field sheets, rock and stream sediment collection cards. Data compilation started ca. 1994.

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.

Index, set up in 1998, to the archive collection of reports, notebooks interpretations, plans and other geological or related data received from external organisations that are not part of other collections. These cover a wide variety of different types and ages of information mainly from Great Britain but some related to BGS projects overseas.

Primary Geological Data resulting from Open Cast Coal exploration. Collection of data includes reports, interpretations and records of research in British coalfield areas deposited by British Coal. Data for past and current collieries and for future prospects. The majority of the collection was deposited with the National Geological Records Centre by the Coal Authority in July 2001. The collection includes borehole site plans, borehole logs , analyses and geophysical data etc. BGS holdings of opencast data are to be integrated with these collections. New data from coal companies will be added as it is received.

High level index to the contents of the boxes of Primary Geological Data resulting from deep underground coal exploration and exploitation in Great Britain donated by the Coal Authority in July 2001. Data for past and current collieries and for future prospects including borehole site plans, borehole logs , analyses and geophysical data etc. This index will diminish in importance as these data are merged with existing collections.

Scanned images of primary Geological Data resulting from deep underground coal exploration and exploitation. Collection of data includes reports, interpretations and records of research in British coalfield areas deposited by the Coal Authority. Data for past and current collieries and for future prospects. The majority of the collection was deposited with the National Geological Records Centre by the Coal Authority in July 2001. The collection includes borehole site plans, borehole logs , analyses and geophysical data etc. A large percentage of this data will eventually be linked to existing collections.

Prime Geological Data resulting from deep underground coal exploration and exploitation produced by the British Coal Board and/or its precursors. The collection dates back to the 18th century and covers all the British coal mining areas and includes borehole site plans, borehole logs, analyses and geophysical data etc. Apart from primary data relating to past and current collieries and for future prospects the information includes reports, interpretations and records of research. The majority of the collection was deposited with the National Geological Records Centre by the Coal Authority in July 2001.
