Map References

The date of the Ordnance Survey edition used for Official puposes is given, in brackets, against the number of each map, e.g. DUR 23.NE (1923) refers to the 1923 edition of Sheet 23 (North East Quarter) for County Durham.

The method of indicating the extent of the workings shown on each plan is that the Six Inch Scale Quarter Sheets of the Ordnance Survey (County Series) have been divided into 1½ inch (¼ mile) squares, lettered vertically A-H and numbered horizontally 1-12, the approximate position of the workings being indicated by the reference squares quoted, thus :—

D12; E11,12; F8,9,10,11,12; G8,9,10,11,12; H9,10,11,12

The plans of abandoned mines are held by the Coal Authority ( https://www.gov.uk/government/organisations/the-coal-authority) at the following address: The Coal Authority, 200 Lichfield Lane, Mansfield, Nottinghamshire, NG18 4RG
