I have a gold mine with workers but it isn't producing. Is there a secret to turning it on?

Alternatively is it possible to vacate it and blow it up?

I emptied all my gold mines and I now have a negative number of gold miners and am losing gold.

Without a manual, it makes it tough to understand whether things are bugs or by design.

Gold mines are bugged in this game. Sometimes you are constantly loosing workers even if they are inside.
Hope they will fix it someday... Very annoying...
