and since working conditions will be extremely hazardous, maybe we would send convicts and otherwise "unwanted" citizens to the mines.
we would of course need to send some form of authority, like a warden, just to keep the convicts (loonies!) under control.
it would also be necessary to set them up with an advanced computer system to handle all colony operations, from telephone switching to ballistics calculations for the throws.
all and all, i don't see how this could go wrong.
