It's a bit of a puzzle as to why there's CO rather than CO2 in the mine - at the moment, the suggestion doing the rounds is that blasting fumes from Hope quarry or one of the Bradwell Moor spar workings are seeping through joints in the limestone. It's still a nasty shock to know that it's lurking in one of the mines out there, especially as I'm going into Moorfurlong mine next week.....
I can imagine. There was a case in a Mexico mine of a miner dying of CO poisoning after blasting but that is not a good analogy really in this case. Although it's the only source that appears credible. As CD once said; How often have I said to you that when you have eliminated the impossible, whatever remains, however improbable, must be the truth?
I wonder. It appears from what I know ( which is very little) that this is the only source of CO in the area. There are in fact very few others. Indeed a bit of a dangerous mystery.
The past is a foreign country: they do things differently there.
