Amazing photo.

Odd that flight is restricted above the hole, yet in the last two photos, there's an airport right next to the hole - the runway almost makes you take off into the hole's path!

I agree Brady. That is odd. But I guess it maybe hard to judge the true distance of the runway from the hole due to the size of the hole. I did receive this piece of spam as a power point presentation and looked to see if the document had any author info. It looks like it was written by Ing. Milan Lánský, Ph.D. from some company called VAKKV. It looks to be legit as far as I can tell.

Well, this changes my whole perspective on things. I rather believe now that diamonds are indeed as special as the television and magazine people say they are. Because,... well, because they come from such special places like this very large hole. It's indeed special for a woman to have and cherish something that comes from a hole this large. And next time my wife gets me riled or in a steamed way, I'm going to remind her of the depths at which mankind will dig for her to have such shiny objects to be adored by all.

If it weren't for the industrial applications diamonds can be used for I'd like to see them banned so this kind of destruction of the environment ceases. I realized years ago that DeBeers created an artificial market for diamonds using advertising that "girl women" are still falling for almost a hundred years later. Sad commentary on our consumer society that girls still fall for "you need a rock worth two months salary in order to prove he loves you."

Unfortunately that is not the world's biggest hole. The Big Hole (the Kimberley Mine) is the world's largest man-made hole, with a depth of 800m/.5mi, a diameter of 470m/1,542ft and a circumference of 1.5km/.9mi. Between 1871 and 1914 22.6 million tons of earth and rock were excavated from the mine for a yield of 2,722kg/6,000lb of diamonds.

Visitors can look down from a viewing platform into the mine, now filled with water to 150m/500ft below ground level, and picture what it was like when thousands of men were working in the hole and hauling the rock up to the surface with cables.

By 1889, when the workings had reached a depth of 400m/.25mi, opencast mining was no longer possible. Later the work was increasingly mechanized, the first winding tower being installed in 1892.

What is more interesting is the fact that this was done without modern technology or machinery, but by hand digging.

Find it at 28°46'7.40"S 24°49'42.87"E on local.live.com or on Google Earth

i thought the biggest hole was in antarctica? maybe im mistaken though. but theres no tellin what the government knows and we dont. im pretty sure there are deeper holes that we arent privy to.

Uh, 24 S by 24 E puts you in South Africa.

Try 62 N by 113 E

In Google Earth town name is Minyy.
Location 62 31 36 N 113 59 36 E.

I thought Colin Powell was the biggest in America.

Believe me, Colin's a good guy compared to the rest.

Diamonds are quite the thing, slavery, unfair trade- you know the deal. And its all for essentially the same thing as graphite: carbon chains
I do find mining as a practice fascinating though, the holes and trucks are just mind boggling at the size they reach, and standing beside one just blows ones mind.
My Question is, where is the world's biggest man made dirtpile? The contaminants from this must be outstanding!

I am not a math expert but I believe that the Kennecott Copper mine in Utah is much larger than this hole, check it out. http://www.kennecott.com/about_facts.html

After comparing the 3 sites, Mirny, Siberia; Kimberly S Africa; and Bingham canyon, utah without a doubt, the hole in Utah is WAY larger than either of the first 2. Kimberly appears to have a smaller diameter than Siberia but with it full of water it's too hard to tell if it is a deeper hole. As for shear volume, Bingham Canyon dwarfs both of these holes combined!

but still, they are all impressive.

I know some people don't like dimond because they fund some bad things. I wish you could find out where diamonds were mined. I was looking at the Rolex GMT Master II and the Mens Rolex Daytona, but they don't have any diamonds. I should probably just stick with either magnetic jewelry or wholesale jewelry instead of the a nice 1 carat diamond.

fantastic site.worth viewing often

thanks rajagopal! Hope you come back.

Correct Kimberley Big Hole is at 28°44'16.74"S, 24°45'32.18"E

That is not a loader...its a truck!

i agree with paul it's a dumptruck not a loader. All the dirt and rock that came out of it would have made a small mountain. But true very interesting site nice work.

I'm sorry but I always thought that the world's largest manmade hole is Bigham Canyon's ( Utah, USA ) Copper Mine. It's more than a mile deep
and 2,5 miles across!

fyi the biggest MANMADE hole in the world is the "The big hole" in Kimberly South Africa

http://www.southafrica-travel.net/kalahari/e6ofs08.htm

No way the "big hole" in South Africa is the largest. The underground Kimberly Mine was mined to a depth of 1097m but the hole itseld is only 215m deep. The Kennecott's Bingham Canyon Mine is 3/4 mile (1207m) deep.

I am very much agreed that this is the biggest man made hole in this universe.

I compared 4 holes here's what I got:
Hole Above:525m Deep
1,25km in Diameter
Kennecott, Utah: 2 1/2 miles across
3/4 a mile deep
Kimbery, Africa: 215 m Deep

Jagersfontein: 700 feet deep

The Jagersfontein is the deepest manmade hole in the world. Kimberly Diamond mine in South Africa is second.

Thanks Y'all
Peace Out Bitches

Somebody obviously doesn't know the difference between miles, meters, yards and feet.

Otherwise they wouldn't have made the glaring mistake of stating the Jagersfontein to be the deepest.

Next time, put them in all the same unit of measurement before deciding which is deepest.

hehe, "Person" sounds like a troller making rediculously stupid and easily/obviously counter-argued false claims just to stir something up.

That or he's a complete moron as Galeon 7 noted and needs to learn the difference in units of measurement... The world may never know. Perhaps the deepest manmade hole in existence is located somewhere in this fellows head?

No way the largest hole of the world is in the kharkala near maloogan (kenya).
its depth is more than 1500 meter its diameter is 300 meter,

but i dont know why media and every one ignoring it..
if you want to see the picture of this whole please visit.

im not sure about the largest (total area) hole on earth, but the deepest hole ever created by man is the Kola well on Russia's Kola Peninsula, near the Norwegian border. It was started in 1970 to explore the earth's crust and has reached over 40,000 ft. (12,192m) in depth. I found it interesting that temps reached 180ºc and water was found in the rock. I'm supprised no one has mentioned it here considering the information is pretty accesible.

Well, thanks for all the info. Each of these holes is unique in its own way. I think people are arguing depth from surface, and altitude, wich are two different things. Way cool though.

Folks,

Scanning through this interesting discussion, I am struck by the fact that what led me to here was a minesite's claim to the 3rd Largest Manmade Hole.

It intrigued me, because I used to work at the 2nd largest, Morenci's in SE Arizona. Before we started backfilling it, it was several thousand feet deep and miles in diameter, and that was BEFORE the extensions got added on to it, which stretch for miles. At the time, we were second behind only Chile's Chuquicamata.

It has always bugged me that Kennecott's Bingham Canyon (UT) publicity machine had them on recond and on Nova claiming they were the biggest.

So, so false by many metrics! You could talk total tons moved, volume displaced, and then compare/contrast the varied three dimensions, but there is no way that the massive copper mines are not the biggest.

Then there's rate. The largest producing mine is Escondida, Chile. But the world mining rate record is over 1.3 million tons in one day, done at Morenci in the late 90's, besting the previous record (Chuqui's) by ~300,000 tons.

It would be interesting to compare all the open pit copper mines. I mean Butte, Montana's nearly swallowed the town. And Anaconda was huge, too. Two near Silver City, New Mexico... Also in Arizona besides Morenci: Bisbee, Globe, Ajo, Bagdad. And others in Chile and Montana.

hello
I LINKED YOU WEB IN MY WEBLOG.

HI
I LINKED YOUR SITE IN MY WEBLOG

Can anybody upload a wikimapia or google-earth link for the same please?? would be really cool to c it for yourself!
