Project Description

Oyu Tolgoi is one of the largest undeveloped copper reserves worldwide. Since 2012, ore has been mined from the Oyu Tolgoi open pit and exported to international markets.

After being extracted from the open pit, the ore is treated by a series of complex processes in the Oyu Tolgoi concentrator to create a fine copper concentrate powder.

Longer term, Oyu Tolgoi LLC is looking to develop the underground phase of the mine, to access the best minerals from deep below the surface where approximately 80 per cent of the value of the Oyu Tolgoi mine is found.

Scope of Work

The installation, termination, testing and construction verification of electrical, instrumentation, controls and telecommunication equipment and cabling for the existing Shaft Farm and new Shaft 2 Surface facilities. The works were split into the separable portions; Shaft 2 Surface Works, Shaft 2 Underground Works, Shaft 2 Production, Services & Auxiliary Hoists Works, Specialist Services Works and Power Factor Correction Works.

Varying works associated with each portion included all works associated with switchrooms, reticulation, underground works below EL -24.0m, all works directly associated with the production, service and auxiliary hoists. In addition, specialised works in all associated facilities as well as works associated with the installation and construction verification of the 35 kV and 10.5 kV power factor correction units were completed.
