Udachnaya pipe

From Wikipedia, the free encyclopedia

Udachnaya pipe (Russian: тру́бка Уда́чная, lit. successful pipe or lucky pipe) is a diamond deposit in the Daldyn-Alakit kimberlite field in Sakha Republic, Russia.^[1] It is an open pit mine,^[2] and is located just outside the Arctic circle at 66°26′N, 112°19′E.^[3]. Udachnaya was discovered on June 15, 1955, just two days after the discovery of the Soviet diamond pipe Mir by Soviet geologist Vladimir Shchukin and his team. ^[4] It is more than 600 m deep.^[4]

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.^[2]
