A number of coal mines have been dug in this general area. These would have been sunk to supply the local farms and villages with fuel. It is unknown exactly when the three shafts were dug here; they are not shown on the first edition of the Ordnance Survey map of the area in 1866. The second edition Ordnance Survey map of the area notes them as "Old" so it might be presumed that they were then inactive.
