I like the staircase in this mine, its quite an unusual feature for a mine. Other bits look quite dangerous with what must have been false floors rotted away.
Glad you like them, I helped repair them moons ago on a working bee weekend!

Looks like you took about the same route we did, that walk up there nearly killed me, but well worth it and that staircase going down felt more than a little worrying

The slate mines must have the largest caverns of any mine type in Britain from the look of them. It seems that slates usefulness as a roofing material is due to it having very low water absorption thus being very resistant to freeze damage and being easy to cleave into thin sheets. It tends to produce high levels of waste material though with sometimes only about 10% of mined rock ending up as actual roof slates.
