hi bob, you may be right in saying that it was a non commercial drift as i have spent the last 2 days on the internet trying to find out any info about the mine with very little success. All i can find is a link on google books that talks about some problems with the reservoirs embankments partly due to subsidence of the mines below. Apparantly from what i read in that link mining was carried out under both reservoirs. The reason i ask is that i beleive i may have found an entry to this mine. A year ago myself and a friend found an over grown entrance, we followed the very tight tunnel which after a while branched off in 2 different directions, they seemed to be heading under each of the reservoirs, we didnt go all the way through though. It was only a couple of days ago that i stumbled across the link that informed me that there was a coal mine on the site.
