Oyu Tolgoi is jointly owned by the Government of Mongolia (34 per cent) and Turquoise Hill Resources (66 per cent, of which Rio Tinto owns a controlling interest of 50.8 per cent). Rio Tinto has been the manager of the Oyu Tolgoi project since 2010. The open-pit mine was completed in less than 24 months and production started in 2013.
A traditional block caving mine considers the development of an undercut level that allows blocky or veined rock masses to fracture, fail, and unravel when the undercut area is large enough. Once caving initiates, the rock mass progressively fails when induced stresses overcome the rock mass strength and when fractured rock …

The mining rock mass rating (MRMR) of Lift 1 is 40–45, and has a predicted critical hydraulic radius of 20–23 m. There are ...
Following a new long-term agreement between Rio Tinto, Turquoise Hill Resources (TRQ) and the Government of Mongolia, underground production has formally started at Oyu Tolgoi. In a major step forward, and after excavation of over 90 km of tunnels over 11 years, the first undercut rings were recently fired at the Oyu Tolgoi …
Turquoise Hill is developing a stage one open-pit mine on the near-surface Southern Oyu deposits and a stage two underground block-caving mine at the Hugo Dummett North and South deposits. The initial development programme for the Hugo North underground block cave mine is currently underway with a 1,385m shaft completed …

It is a complex greenfield project comprising an underground block cave mine and copper concentrator as well as an open pit mine which has been successfully operating for almost ten ...
Oyu Tolgoi is one of the most exciting developments in copper and gold mining in the last several decades. ... Average tunnel height and width. ... Deepest reaching 1.3KM. See how we use block caving to transport the ore body at Oyu Tolgoi Growth. Global demand for copper is set to grow, driven by urbanisation, industrialisation and increasing ...
Before explosives in the form of gunpowder were introduced to mining in the 1600s, miners carved rudimentary small-scale stopes by hand.. Gunpowder was replaced by dynamite in the mid-1900s, and power tools and machinery followed shortly after. As technology progressed, so did the mine design process.

The development stage of block caving infrastructure needs 3-5 years until ready for continuous production. The existing block caving projects have a life of mine for production, ranging from 12 to 35 years. Thus, we propose a long-term concession, about 15 until 40 years, covering development and operational production stages.
