Canadians have been underground farming in mines for nearly two decades now, in order to grow cannabis for the government of all things. Couldn't find any coal mines being used for this, they seem to mostly be copper. - https://webcache.googleusercontent.com/search?q=cache:_ddjRs...

That's funny.
..and ok sure, I concede exceptions. In that case, I think (1) the tradition is of hiding from the law has produced quirky horticultural practices (piping in air and exhaust for plants is normal) (2) they don't really care about unit costs and (3) they're growing a plant that costs $10k per kg! They need security like a jewelry shop.
First, despite all the kickstarters for urban, vertical, undeground or underwater lettuce farms... Lettuce farms are fine where they are. If you want LED grown lettuce, they can grow that there too. Grow outside the city and drive produce to the city in a car. If you want to go green, use an electric car.
There's no need for the farm to be underground... on earth, at this point in time.
This besides the (insightful) about how hard it is to make mines safe to access, barley safe, assuming a very active safety system.
