RE: RE: GXSThat's the Diavik diamond mine. I thought it was in the caption somewhere. There is certainly a cost-benefit ratio thingy there.
Wet is better than dry, though. It is easier to get rid of water than to find it and bring it in. Anyways, water will have to be removed regardless. Once a big hole is made, water naturally will want to accumulate.
A good mine is the reverse of a boat (a hole in the water you pour money into).
