Is it really true that at -150m depth that the air pressure would be 20 atmospheres? It doesn't seem like it is likely, the air pressure at +150m is scarcely different from sea level.
- beardyw 4y agoHa, just made the same point below.
- jacknews 4y agoThis is more like the pressure under 150m of water. 150 deep in a mine is about 1.02 atm. You'd need to go about 30km down to get 20 atm.

- saalweachter 4y agoRandom googling says -5km in a mine is like +0.6 atmospheres.
