Abandoned mining town (different to villages)

So how about this for an idea... Small mining shacks lets say 3x4 so enough for a bed and storage but slowly decaying (missing roof & blocks). Then a main mining centre where you obviously go down this mine (this would work perfectly with C&C Pt 2) then a small area where everything gets refined (chests would sometimes contain pickaxes (depending what the mine is rich on or has potential to drop). If this is taken into consideration then the spawn rate for such structure should be 15-20% giving players an opportunity of finding and exploring the derelict town plus whatever the mine holds below. Also, TNT should be placed (maybe as a rigged trap or maybe not) could spice it up and make it more of a challenge getting back out. Who knows what may or may not happen but Minecraft definitely holds so much potential!
