Whilst I am sure this is true, at earlier times home-grown hardwood
was of course used. In the Wyre Forest there are frequent accounts of
sales of pit timber in the 18th and 19th Century; coppiced oak, I would
imagine. Indeed, a forestry worker recalled this type of timber still
being marketed until at least the 1920s. I have been told a lot of
English hardwood was also used in the 2nd World War.
None of this of course helps with the original query about Spanish
Chestnut, but I would assume it would be used for timbering of the
workings.
I have seen analyses if timber recovered from open-cast workings but I
don't have those to hand at the moment.
