In terms of the game's story-arch unfolding, discussion of the mine itself doesn't really come up again, so in that regard there's no lasting consequence (that I'm aware of).

There are a few logical RP reasons to consider leaving it accessible, though. Primarily, it's now the only known working mine on the Sword Coast, as Nashkel has been rendered useless for however many years to come. Theoretically, Gorion's ward will tell the ruling elite of Baldur's Gate about it, who will send the Flaming Fist to guard it, who will free the slaves, and eventually a road will be cut; either through Cloakwood from the Friendly Arm Inn, or across the river from the southern shore of Baldur's Gate.

...but then, this will all take time, and flooding the mine is a quick fix; free's the slaves and stops all future shipments for the Iron Throne. Besides, (again theoretically) if the region needs the mine badly enough, it can likely be un-flooded again.
