350 is good enough. Ramp is a big saving. 2 mill is dort cheap. I have one I could get going for about the same. Dratted POG.

Wood is always good in a mine. It won't rot underwater. Steel won't rust appreciably either in massive quantities but nails disappear. You have to rebuild all ladders. If you don't sell the stuff it what will you do with it? Most defunct operations never get going again, even with reserves. Hollinger, Mleod.

Flame that won't burn could mean CO or NOX. Good idea to scram. Good idea never to light match. Carry a Davies lamp instead. Methane at 9% is very bang-bang stuff. Screen in lamp prevents combustion. You watch for flame that goes out or flame that burns coloured and brightly.(Methane) It comes from the decomposing wood that may be exposed in air pockets. If you turn your lamp off you can see the soft green light of phosphorescent rot. Best to blow air in advancing duct headings. Always turn fan on after you exit mine. Otherwise bad gas blows back at you and kills you. (Has happened) H2S is THE gas to avoid next to NOX (after blast gas). Very quick. Old Sulfide mines have lots.

Poor deoxygenated air is common in mines. In Cobalt the oxygen was down around 15 %. A match would not stay lit. They believe it was because the chute's water-head compressor absorbed oxygen from the air.
