Among the amaz­ing nat­ur­al phe­nom­e­na, one can cer­tain­ly include holes peri­od­i­cal­ly open­ing up in dif­fer­ent places on the globe.

biggest holes in the earth

1. Kim­ber­lite pipe “Mir” (Mir dia­mond pipe), Yaku­tia.

1Kika-mir-4

The Mir kim­ber­lite pipe is a quar­ry locat­ed in the city of Mirny, Yaku­tia. The quar­ry has a depth of 525 m and a diam­e­ter of 1.2 km and is one of the largest quar­ries in the world. Min­ing of dia­mon­dif­er­ous kim­ber­lite ore was stopped in June 2001. Cur­rent­ly, an under­ground mine of the same name is being built on board the quar­ry to devel­op the remain­ing under-quar­ry reserves, the extrac­tion of which by open pit is unprof­itable.

2.Kimberlite pipe “Big hole” South Africa.

Big Hole — a huge inac­tive dia­mond mine in the city of Kim­ber­ley (South Africa). It is believed that this is the largest quar­ry devel­oped by peo­ple with­out the use of tech­nol­o­gy. It is cur­rent­ly the main attrac­tion of the city of Kim­ber­ley.

Between 1866 and 1914, about 50,000 min­ers dug the shaft with picks and shov­els, pro­duc­ing 2,722 tons of dia­monds (14.5 mil­lion carats) in the process. Dur­ing the devel­op­ment of the quar­ry, 22.5 mil­lion tons of soil were extract­ed. It was here that such famous dia­monds as “De Beers” (428.5 carats), bluish-white “Porter Rhodes” (150 carats), orange-yel­low ” Tiffany” (128.5 carats). At present, this dia­mond deposit has been exhaust­ed. The area of ​​the “Big Hole” is 17 hectares. Its diam­e­ter is 1.6 km.[1] The hole was dug to a depth of 240 meters, but then was filled with waste rock to a depth of 215 meters, cur­rent­ly the bot­tom of the hole is filled with water, its depth is 40 meters.

At the site of the mine ear­li­er (about 70 — 130 mil­lion years ago) there was a vol­cano mouth. Almost a hun­dred years ago — in 1914, the devel­op­ment in the “Big Hole” was stopped, but the gap­ing mouth of the pipe remains to this day and now serves only as a bait for tourists, act­ing as a muse­um. And…begins to cre­ate prob­lems. In par­tic­u­lar, there was a seri­ous dan­ger of col­lapse not only of its edges, but also of the roads laid in its imme­di­ate vicin­i­ty. The South African road author­i­ties have long banned the pas­sage of heavy goods vehi­cles in these places, and now they strong­ly rec­om­mend that all oth­er dri­vers avoid dri­ving along Bult­fontein Road in the Big Hole area. The author­i­ties are going to com­plete­ly block the dan­ger­ous sec­tion of the road. And the largest dia­mond com­pa­ny in the world, De Beers, which has owned this mine since 1888, did not find any­thing bet­ter than to get rid of it by putting it up for sale.

The largest active quar­ry in the world — the devel­op­ment of cop­per began in 1863 and is still going on. 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 an open pit mine.

As of 2008, it mea­sures 0.75 miles (1.2 km) deep, 2.5 miles (4 km) wide and cov­ers an area of ​​1,900 acres (7.7 sq km).

The ore was first dis­cov­ered in 1850, and quar­ry­ing began in 1863, which con­tin­ues to this day.

The quar­ry cur­rent­ly employs 1,400 peo­ple who extract 450,000 tons (408 thou­sand tons) of rock dai­ly. The ore is loaded onto 64 large dump trucks capa­ble of haul­ing 231 tons of ore, these trucks cost about US$3 mil­lion each.

4. Quar­ry “Dyavik” (Diavik), Cana­da. Dia­monds are mined.

1350592376_c340ff289b

The Cana­di­an quar­ry “Diavik” is per­haps one of the youngest (by devel­op­ment) dia­mond kim­ber­lite pipes. It was first explored only in 1992, the infra­struc­ture was cre­at­ed by 2001, and dia­mond min­ing began in Jan­u­ary 2003. Pre­sum­ably, 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, about 220 km south of the Arc­tic Cir­cle, off the coast of Cana­da. Since the hole is huge, and the island in the mid­dle of the Pacif­ic Ocean is small, only 20 km²

and in a short time the Diavik dia­mond mine became one of the most impor­tant com­po­nents of the Cana­di­an econ­o­my. Up to 8 mil­lion carats (1600 kg) of dia­monds are mined from this deposit annu­al­ly. An air­field has been 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 stud­ies and begin con­struc­tion on Canada’s North Shore of a major port to receive car­go ships up to 25,000 tons, as well as a 211 km access road that would con­nect the port to the con­sor­tium’s plants. . And this means that the hole in the ocean will grow and deep­en.

5. Great Blue HoleBelize.

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

6. Drainage hole in the reser­voir of the Mon­ti­cel­lo dam.

A large man-made hole is locat­ed in North­ern Cal­i­for­nia, USA. But it’s not just a hole. The drain hole in the reser­voir of the Mon­ti­cel­lo Dam is the largest spill­way in the world! It was built about 55 years ago. This fun­nel-shaped exit is sim­ply indis­pens­able here. It allows you to quick­ly dump excess water from the tank when its lev­el exceeds the allow­able rate. A kind of safe­ty valve.

Visu­al­ly, the fun­nel looks like a giant con­crete pipe. It is capa­ble of pass­ing through itself in a 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 exits from the oth­er side of the dam, remov­ing excess water when the reser­voir over­flows. The dis­tance from the pipe to the exit point, which is locat­ed slight­ly to the south, is approx­i­mate­ly 700 feet (about 200 m).

A giant fun­nel 150 meters deep and 20 meters in diam­e­ter. Caused by ground­wa­ter and rain. Dur­ing the for­ma­tion of the fail­ure, sev­er­al peo­ple died and about a dozen hous­es were destroyed. Accord­ing to local res­i­dents, from about the begin­ning of Feb­ru­ary, ground move­ments were felt in the area of ​​u200bu200bthe future tragedy, and a muf­fled rum­ble was heard from under the ground.
