A Diamond Mine in Siberia
A Diamond Mine in Siberia - Amazing PowerPoint Slide Show
Stuck away on the island that is Great Britain, Will and Guy have no idea what goes on in outer Siberia. John Franklin has given a glimpse into the dark, cold, unknown mine workings. What amazed us most about the slides was the sheer scale of the mine operation.
Siberian Diamond Mine - Perspective
Siberian Diamond Mine
Will and Guy think that these holes are not only remarkable, but some of them are terrifying; the sheer scale of them reminds us of our own size on this planet. We have researched these with the help of a regular contributor, John Reeves, and they complement well the PPT Presentation of the Mirny mine in Siberia.
1. Kimberley Big Hole - South Africa
Apparently the largest ever hand-dug excavation in the world, this 1097 meter deep mine yielded over 3 tons of diamonds before being closed in 1914. Some of the diamonds found at Kimberley are over 80 carats.
2. Glory Hole - Monticello Dam, California
A glory hole is used when a dam is at full capacity and water needs to be drained from the reservoir
This is the 'Glory Hole' at Monticello dam, and it's the largest in the world of this type of spillway, its size enabling it to consume 14,400 cubic feet of water every second.
At first sight this, and other glory holes, looks like a fake, but we assure that this is a real if man-made phenomenon.
3. Bingham Canyon Mine, Utah
Bingham Canyon is supposedly the largest man-made excavation on earth. Extraction began in 1863 and still continues today, the pit increasing in size constantly. In its current state the hole is � miles deep and 2.5 miles wide.
To the east is Salt Lake City, to the west the Utah Salt Flats.
4. Great Blue Hole, Belize
This incredible geographical phenomenon known as a blue hole is situated 60 miles off the mainland of Belize. If you go to the very south-east of Mexico, Belize is a tiny Central American country facing towards Cuba.
There are numerous blue holes around the world, but Will and Guy think there is none as stunning as this one.
5. Diavik Mine, Canada
This mine is so huge and the area so remote that it has its own airport with a runway large enough to accommodate a Boeing 737. It looks equally pretty when the surrounding water is frozen.
