IAMA Electrician at the deepest nickel mine in Canada. AMA
I work at Creighton Mine in Sudbury, Ontario. I have done an AMA about 8 months ago, but there has been interest for me to do another. So AMA!
jftduncan pointed out a couple cool facts about Creighton in another thread,m thought I'd share them here:
Some other things that are fairly unique about kyriose's mine: *has continuously operated since roughly 1910s. *it is seismically active, it experiences seismic events of about 2.0 on a fairly regular basis. *It is a thermal mine. The ambient temperature can be >30C in some parts of the mine or hotter if there is equipment operating in the area. *To deal with the heat, it has a natural heat exchange system where fresh air for the mine is drawn through old workings. This has the effect of heating the air during the winter months and cooling the air in the summer. *is host to an underground scientific laboratory. Due to it's depth at 6800' below surface, it is the cleanest lab with respect to cosmic radiation. allowing them to do experiments studying nutrinos and the search for dark matter.
Edit 1: I am trying to answer everyones questions, I didn't think that this would be so big! I have to leave for work now but I will try to answer as many as I can when I can.
Edit 2: Sorry guys I got lined up with a lot of work tonight, I will be going down to an older part of the mine so I'll take a ton of pictures.
Edit 3: jeezus84 did a coop in the SNO lab, and since everyone seems to be interested in that here are some pictures he linked me.
Edit 4: I went down 3-shaft tonight which is the shallowest of the shafts here at Creighton. I took some pictures so you could get a decent idea of what it looks like down there, as well as a couple videos. Not sure if you can share video on imgur but I will try as I don't have access to YouTube at work. The furthest I went down today is 1900, but I got to go to some creepy old areas and get the best pictures I could in near complete darkness. My work computer's internet access kind of REALLY sucks so I'll have to upload them when I get home tonight.
