Blue hole belize

The holes that periodically open in different places of the globe can certainly be attributed to the number of amazing natural phenomena.

The kimberlite pipe “Mir” is a quarry located in the town of Mirny, Yakutia. The open pit has a depth of 525 m and a diameter of 1.2 km, and is one of the largest open-pit mines in the world. The mining of diamondiferous kimberlite ore was discontinued in June 2001. At the present time, an underground mine of the same name is being built on board the quarry, for mining the remaining underground reserves, the excavation of which by the open method is unprofitable.

The world’s largest diamond mining quarry is amazing.

The big hole is a huge inactive diamond mine in the city of Kimberley (South Africa). It is believed that this is the largest career, developed by people without the use of technology. It is currently the main attraction of the city of Kimberley.

From 1866 to 1914, about 50 thousand miners dug a mine with the help of picks and shovels, developing 2,722 tons of diamonds (14.5 million carats). During the development of the quarry 22.5 million tons were extracted

At the site of the mine before (about 70 – 130 million years ago) there was a mouth

3. Kennecott Bingham Canyon Mine Quarry, Utah.

The world’s largest active quarry – the development of copper began in 1863 and is still in progress. About a kilometer deep and three and a half kilometers wide.

It is the world’s largest anthropogenic formation (dug out by man). It is a mine the development of which is conducted by the open method.

It has dimensions as of 2008: 0.75 miles (1.2 km) deep, 2.5 miles (4 km) wide, and covers an area of ​​1900 acres (7.7

Ore was first discovered in 1850, from 1863 began the development of a career that continues to this day.

Currently, 1400 people are employed in the quarry, who daily extract 450,000 tons (408 thousand tons) of the breed. The ore is loaded into 64 large dump trucks that are capable of carrying 231 tons of ore, these trucks cost about $ 3 million each.

4. Career "Devil" (Diavik), Canada. Diamonds are mined.

The Canadian “Diavik” quarry is perhaps one of the youngest (in terms of development) diamond kimberlite pipes. It was first investigated only in 1992, the infrastructure was created by 2001, and diamond mining began in January 2003. Supposedly the mine will last from 16 to 22 years. The place of its exit to the surface of the earth is unique in itself. Firstly, this is not one, but three pipes at once, formed on the island of Las de Gras, approximately 220 km south of the Arctic Circle, off the coast of Canada. Because the hole is huge, and the island in the middle of the Pacific is small, only 20 km²

and for a short time, the Diavik diamond mine has become one of the most important components of the Canadian economy. Up to 8 million carats (1600 kg) of diamonds per year are extracted from this deposit. An airfield was built on one of its neighboring islands, capable of receiving even huge Boeings. In June 2007, a consortium of seven mining companies announced their intention to sponsor environmental research and start building a large port on the northern coast of Canada to receive cargo ships of up to 25,000 tons, and 211 km of access road that connects the port with consortium plants . And this means that the hole in the ocean will grow and deepen.

5. Great Blue Hole, Belize

The world-famous Great Blue Hole (“Great Blue Hole”) is the main attraction of the picturesque, environmentally clean Belize (formerly British Honduras) – the state in Central America, on the Yucatan peninsula. No, this time it is not a kimberlite pipe. From it, not diamonds are mined, but tourists – diving enthusiasts from around the world, thanks to which it feeds the country no worse than a diamond pipe. Probably, it would have been better to call it not the “Blue Hole”, but the “Blue Dream”, since this can only be seen in dreams or in dreams. This is a genuine masterpiece, a miracle of nature – a perfectly round, twilight-blue spot in the middle of the Caribbean Sea, surrounded by Lighthouse Reef’s lace front.

Width is 400 meters, depth is 145 – 160 meters.

As if sailing over the abyss …

6. The drain hole in the reservoir of the dam Monticello.

A large man-made hole located in Northern California, United States. But this is not just a pit. The opening of the drain in the reservoir of the dam Monticello – the largest spillway in the world! It was built about 55 years ago. This funnel outlet is simply indispensable here. It allows you to quickly dump excess water from the tank when its level exceeds the allowable rate. A sort of protective valve.

Visually, the funnel looks like a giant concrete pipe. It is able to pass through itself per second as much as 1370 cubic meters. m of water! The depth of such a hole is about 21 m. From top to bottom it has the shape of a cone, the diameter of which at the top reaches almost 22 m, and narrows down to 9 m and goes out from the other side of the dam, removing excess water when the reservoir is full. The distance from the pipe to the exit point, which is located slightly to the south, is approximately 700 feet (about 200 m).

7. Karst failure in Guatemala.

Blue hole belize

Giant funnel depth of 150, and a diameter of 20 meters. Caused by groundwater and rain. During the formation of the failure, several people died and a dozen houses were destroyed. According to local residents, around the beginning of February, in the area of ​​the future tragedy, there were movements of the soil, and a muffled hum was heard from the ground.
