The Udachnaya pipe (Russian: тру́бка Уда́чная, literally lucky 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 at 66°26′N 112°19′E.
The Udachnaya pipe
Location in Russia
Udachnaya was discovered on 15 June 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 (1,970 ft) deep, making it the third deepest open-pit mine in the world (after Bingham Canyon Mine and Chuquicamata).
The nearby settlement of Udachny is named for the deposit.
As of 2010, Udachnaya pipe is controlled by Russian diamond company Alrosa, which planned to halt open-pit mining in favor of underground mining in 2010.
The mine has estimated reserves of 225.8 million carats (45.16 t) of diamonds and an annual production capacity of 10.4 million carats (2.08 t).
