Utterly Fantastic! The world's biggest hole is in Russia. The giant hole is actually a diamond mine in Eastern Siberia near the town Mirna. It is 525 m deep , and 1.25 km in the diameter. 525 m= 326 of a mile or 1722.42 ft 1.25 km = .777 (little over 3/4) of a mile or 4101 ft. This loader is one of the biggest in the world: length--13.36m, width--7.78m, height--6.65m. 13.36 m = 43.83 ft. long 7.78 m = 25.52 wide 6.65 m = 21.82 ft. high The giant machine appears just a small point in the next image. The giant machine is to the right about 1/2 way down. The suction above the hole resulted in several helicopter crashes, so all flight above the hole is prohibited. A view from a satellite
