So I was out walking today, and I came across a nice steep embankment which I thought to myself would be excellent to dig a tunnel into if I only knew how to properly do so without it collapsing on me and killing me. After a brief period of research, I've come to recognize that the internet seems to be largely devoid of any well put together articles on how to dig your own tunnel in such a way as to not get yourself killed in the process. You folks wouldn't by any chance happen to know a thing or two about such things or be able to point me toward such information, would you? Stuff like how to construct proper supports, how frequently to put them in, what kind of lumber I should use, how wide and tall such a tunnel could safely be, and the like.
That probably sounds strange, and I'm probably the weird one here, but whatever.
