How far did the collieries go, about this far!
There were approx 35 shafts altogether.
The shaft locations detailed below are fairly accurate, but I cannot vouch for their accuracy, I've simply done my best with the maps available.
I'm writing a short history of the underground workings.
These maps (photos) show some of the early original maps from Mr. AAS Photoshopped onto Google Earth using the known locations of the shafts to obtain the scale of the workings and the direction of the workings. RAF Aerial photos (1940's) from the NMR were also used to obtain more accurate shaft locations.
Little Neston Collieries (closed around 1855, one reopened in the 1920's for a very short period)
Wirral / Neston Colieries (closed around 1928 (?)). Shows various seams, and an underground inclined plane.
This map shows only the limits of the underground workings. The curvy red line is the approx limit of the coal measures.
Note that it crosses the coastline approx near the stream from Neston sewerage works.
If you look in the bottom of the brook, under the footbridge, you can often pick out lumps of Neston coal.
