Maptek and IT Experts LLC have delivered an I-Site 8200 3D laser scanning system to Thiess for the Oyu Tolgoi (OT) copper-gold underground project in Mongolia’s South Gobi Desert. Thiess will also use I-Site Studio software with conformance reporting.
Thiess, in joint venture with local contractor Khishig Arvin, is delivering the boxcut and decline project for the major OT underground project.
The boxcut will provide a safe and secure entrance for the underground tunnels and conveyors expanding over 10km and depths of up to 1300 metres. The twin declines will provide up to 395 metres of vertical lift with a maximum gradient of 18%.
The conveyor to surface declines will consist of 16.6km of tunnels and 35,000 cubic metres of large excavations to house the required conveyor transfer and drive stations.
Oyu Tolgoi is jointly owned by the Government of Mongolia with 34% and Turquoise Resources with 66%, of which Rio Tinto owns 51%. Rio Tinto has managed the Oyu Tolgoi project since 2010.
Maptek says its I-Site laser scanners are safe, portable and versatile. The I-Site 8200 system is suited to underground drive mapping and above ground survey applications.
