>Yeah but I find the aesthetic of cliffside slums too cool so I'm going with it
You can have cliffside slums attached to a mine without tossing people in a pit nobody would ever build in while a mine is in operation since it would be in the way or after a mine has been stripped since it would be a godforsaken hole in the ground. Plenty of non-strip mines are in mountainsides and they'll end up with camps and then towns built around them that can then go bust when the mine runs out. Wouldn't be that weird for one to turn into a slum.

Literally just ditch the strip mine part and your idea is completely fine.
