World's biggest hole :
The world’s biggest hole Mirny Diamond Mine is located in Russia. The giant hole is actually a diamond mine in Eastern Siberia. It is 525 meters deep and 1.25 km in the diameter.
Chris Huhne plans to trump that with a hole 1000 meters deep, 26 km square and filled with high level nuclear wastes.
