It's actually the mining tree, from Twilight Forest. True, you need to obtain the sapling through exploration, but it is fairly powerful.
It will gradually transpose any and all ore veins around itself upwards, making them swap places with the blocks directly above them, over and over until they reach the surface. You can quite literally plop this thing down somewhere and go away, only to return to a massive mound of ore that keeps growing out of the ground in front of your very eyes as you mine it.
The result is a completely undisturbed underground, no hollows and branch tunnels like the IC2 miner creates. You might have to fill in some dirt at the top in order to counteract the fact that you are removing ore blocks, but that's it. It easily pulls an entire inventory's worth of ore up.
