Dear Roger,
I agree with you. At the underground slate quarries I used to own quarrymen
was the term used - & historically so as well - this also applies to the
Welsh slate quarries. However, coal, copper & of course quite a few other
minerals are open cast worked, so are they mines or quarries???!!!! I am sure
this subject will go on(!), I have seen this matter raised many times!
Regards, Bernard
