pipe is a diamond deposit in the Daldyn-Alakit kimberlite field in
Sakha Republic, Russia. It is an open-pit mine, and is located just
outside the Arctic circle. Udachnaya was discovered on June 15, 1955,
just two days after the discovery of the diamond pipe Mir by Soviet
geologist Vladimir Shchukin and his team. It is more than 600 metres
(1980 ft) deep.
As of 2004, Udachnaya pipe is controlled by Russian diamond company Alrosa, which plans to halt open-pit mining in favor of underground mining in 2010.
