Holme Bank chert mine was worked from c.1800 up to 1960. There are extensive workings, notable for the large packwalls used to support the roof after the chert beds had been removed. The last company to operate the mine (Smiths Runners) also manufactured davie blocks for building, and continued to do so on site up to about 1995. Much of the surface plant is still on site.
The mine itself is like a maze with passages forking off every few hundred yards.

no idea why lightroom decided to add a sig to this pic
