Lots of/most mines naturally flood. Active mines typically run pumps to remove water that seeps in.

I believe by flooding the mines would cause more trouble than than it would be worth. The are area in the mine would have to be sealed to prevent a leak. A more simple solution would to be run piping into the mines and bury them. The water running through the pipes would still be heated, and there would be less of a chance of leakage.
