Compared to most of the worlds current working tunnels dug by the other 6 billion, or all tunnels 70+ year ago it's a mansion in the tunnel world. In the first world corporate mining industry I'm sure it'd give a safety person a heart attack. Going 10 meters down an artisan mine [1] (most of the worlds miners work in these) is scary. Straight down a narrow hole, then sideways into soft dirt with a few tree trunks holding up dirt doesn't fill you with confidence. Then I got stuck trying to climb out because my longer western legs couldn't step up. The fact this blogger uses welded supports on an outer layer shows he's on probably top of it for the hobby world. [1] https://imgur.com/a/hUgEblt https://imgur.com/a/hUgEblt
