Mirna Diamond mine
THE HELICOPTER SUCKING DIAMOND PIT- Mir/Mirny Diamond Mine, Eastern Siberia, Russia The now inactive diamond pit is the second largest man made hole in the world after Bingham Canyon Mine, Utah, US. Closed since 2004, this pit is 525 m deep and has a diameter of 1.2 km. Its construction stated in 1957 after the Soviet geologists Yuri Khabardin, Ekaterina Elagina and Viktor Avdeeno, in 1957, claimed that there were good chances of discovering diamonds here. The downward airflow of this pit - which was operational for roughly 47 years and produced 2,000 kilos of diamonds per year - pulled aircraft that flew over it. Also, the harsh Siberian cold would flatten tyres and freeze the machinery in the mine. The downward air flow into this mine had sucked in a few helicopters flying over it till ti was declared a no-fly zone. Though a few companies continued to mine here post the fall of the USSR, in the 1990s, curtains were called on the mine 2004.
