Adventure Idea: Goblin infested mine

I have been playing around with an abandoned mine in a forest as a plot for the campaign I DM. Probably going to set it up so that goblins have taken over and the mine owner would like the party to clear it out. Obviously, there will need to be a mine map to accompany this exterior map.

What improvements do you think would need to happen to include this map in one of our published adventures?
