Tried Buckley History Society?The y have a web page,and hold meetings (once a month I think).You could try Buckley library: They sell CD rom full of hundreds of archive photos of all aspects of Buckley such as local clay/coal industry.Takes a lot of sifting through if looking for something specific,but still worth a look.
I know of at least three locally capped mine heads in that area (the `know(le) hill).and there are many tales of houses being unknowingly built over mining areas and collapsing overnight!`Strong possibility`of tunnels under my house apparently,according to the estate agents survey (mine caps about 2 minute walk away).
