The 1km Hex Mining Hazard (Not Including Coal) v7 dataset shows areas of known underground mining (Not Including Coal), identified with an indication of the level of hazard associated for each site. The presence of former underground workings, particularly where shallow, may collapse and cause surface settlement which is used to identify potential hazard at each site. The rating is based on a Low (limited mining known to have occurred) to High (underground mining is known to have occurred) scale. The dataset covers areas of known underground working in Great Britain. The coverage is not comprehensive as areas with no evidence of underground working are unclassified. Underground extraction of minerals and rocks has taken place in Great Britain for more than 5000 years. This dataset draws together a range of diverse information; the geology, the primary constraint on distribution; additional information sourced from published literature and knowledge from BGS experts. Derived from the original MiningHazardNotIncludingCoalGB_v7 dataset, this layer generalises these data into a Hex grid format, with an effective hexagonal grid resolution of 2.6km coverage area (side length of 1km). The dataset was created to provide a comprehensive overview of Great Britain's long and complicated mining legacy. It provides essential information for planners and developers working in areas where former underground mine workings may have occurred. Also for anyone involved in the ownership or management of property, including developers, householders and local government.

**No longer exists**The dataset comprises the published annual reports of approximately 180 companies involved in mining or mining-related activities. The great majority are in English or are bilingual with English. A 5-year collection is maintained on a rolling basis, i.e. only the most recent 5 years' reports are retained. The dataset comprises the reports companies deemed to be the most important in minerals production world-wide. The collection is incomplete as many companies now distribute their annual reports via their web sites rather than send printed copies.

There are three Mining licences as follows: Mining licences This layer shows the spatial distribution of mining licences currently held by companies in Northern Ireland. Each individual licence is shown in outline. January 2010 Mineral Prospecting Licences This layer shows the spatial distribution of mineral exploration licences held by companies in Northern Ireland. Each individual licence is shown in outline Historic Licence Areas This layer shows the spatial distribution of historic mineral licence boundaries in Northern Ireland. The areas where the boundaries of the licences layers appear to overlap reflect temporally different licence periods for the same area. Further information on this data set is available from GSNI (Contact Mark Patton, e-mail: mark.patton@detini.gov.uk).

The data shows the extent of mining within Great Britain it was captured in 1990 by OVE ARUP on behalf of the Department of Environment as a series of paper maps and no updates have been carried out. The data has been converted to a digital format (ESRI Shapefile) by BGS in 1995. The original scale of the data was 1km square. The dataset has limited attribution indicating type i.e. metalliferous, rock, coal, deneholes (chalk), evaporites or ironstone, and whether definitive evidence was found. Although every effort has been made to attribute the digital data to the original maps some inconstancies may have arisen due to data conversion process.

Old card index of quarries in England, Wales and Scotland dating mostly from 1939 to 1963: about 7000 cards, each referring to one quarry. England & Wales cards are arranged by BGS 1-inch (now 50k scale) geological sheet, Scottish cards by county. At best, cards indicate county, geol-sheet, rock type, name, grid reference, locality, owner, date of record and cross references to BGS samples.

Underground extraction of minerals and rocks has taken place in Great Britain for more than 5000 years. The dataset draws together a range of diverse information; the geology, the primary constraint on distribution; additional information sourced from published literature and knowledge from BGS experts. Areas of known underground mining are identified with an indication of the level of hazard associated for each site. The presence of former underground workings, particularly where shallow, may collapse, causing surface settlement or subsidence. The type of material mined, age and extent of working (where known) is used to assess and classify the hazard at each site. The value is based on an A (mining is not known to have occurred) to E (evidence of extensive underground mining is known) scale. Mining Hazard (not including coal) covers areas of known underground working in Great Britain. The coverage is not comprehensive as areas with no evidence of underground working are not included in the data. The dataset was created to provide a comprehensive overview of Great Britain's long and complicated mining legacy. It provides essential information for planners and developers working in areas where former underground mine workings may have occurred. Also for anyone involved in the ownership or management of property, including developers, householders and local government.

Data relating to project specific sites of investigation into fluid processes in landfills and mine sites.

The dataset uses the outline of the mining hazard not including coal in Great Britain data but has been re-attributed to reflect the potential affect of underground drainage. It excludes areas of Coal mining as these are covered by the Coal Authority and therefore are not included in this dataset. It has been reattributed from the A-E rating scale indicating the increasing likelihood of an underground mining hazard to a 1-4 scale identifying the likelihood of susceptibility to infiltration. The data was created using expert knowledge to reattribute the original mining area polygons.

[This metadata record has been superseded, see http://data.bgs.ac.uk/id/dataHolding/13606289] Scanned images of 78 maps covering 13 National Grid 1:10,560 map areas in the area of the Lothian oil-shale field. Each map shows the extent of a single oil shale seam. They were published between 1977 and 1982 by the Institute of Geological Sciences in Edinburgh. The original maps were scanned in 2014.

A collection of seventy-eight maps covering thirteen National Grid 1:10 560 map sheets in the area of the Lothian oil shale field published between 1977 and 1982. Each map shows the extent of a single oil shale seam. An oil shale seam refers to a layer or deposit of sedimentary rock rich in organic material known as kerogen, which has the potential to yield hydrocarbons such as oil and gas through a process called pyrolysis. Oil shale is different from conventional oil and gas reservoirs in that the hydrocarbons are not present in a liquid or gaseous form but are trapped within the solid structure of the shale rock. The maps were published by the Institute of the Geological Sciences in Edinburgh (previous name for the British Geological Survey). This entry relates to hardcopy maps stored in the National Geological Data Centre (NGDC) and digital files produced by scanning them, as well as any derivative files. These maps are hard-copy paper records stored in the National Geoscience Data Centre (NGDC).
