Stockholm, Sweden, February 24, 2010: Atlas Copco has been selected by Rio Tinto to develop one of two rapid tunneling concepts for underground block cave projects. The new machine will enable fast and cost-effective construction of mines which are safe, productive and have a minimal impact on the environment.
Rio Tinto’s development of projects such as Resolution Copper in Arizona and Oyu Tolgoi in Mongolia will use an underground block cave mining method. This method requires construction of significant underground infrastructure prior to the production of ore. In anticipation of this need, Rio Tinto Technology and Innovation began investigating alternative construction methods to further improve both safety and speed of constructing underground block cave infrastructure such as shafts and tunnels.
The Atlas Copco Modular Mining Machine (MMM) is a new tunneling machine that utilizes the learnings of the Atlas Copco Robbins Mobile Miner. This mechanical rock excavation system is anticipated to be able to achieve more than twice the performance of normal tunneling methods in the expected ground conditions. The cooperation between Rio Tinto and Atlas Copco on the development of this machine has been underway for some time and is approaching reality. The Rio Tinto and Atlas Copco team have agreed to share further information on this mining breakthrough with the mining community at the upcoming SME conference in Phoenix Arizona, March 1-3, 2010.
“We are excited to have this opportunity to work with a leading mining and mining development company, such as Rio Tinto, whose vision and solid knowledge will be vital in developing this machine,” said Björn Rosengren, Business Area President of Atlas Copco Construction and Mining Technique. “Many of our best products result from close collaboration with customers like Rio Tinto who, as we, are always looking for continuous improvement. Developing the Modular Mining Machine demonstrates that we have the technical knowhow to provide sustainable productivity under nearly any circumstances, and we are devoted to its successful realization.”
John McGagh, Rio Tinto Head of Innovation, said: “We are very pleased that the Atlas Copco team, with many years of experience in different novel rock excavation techniques, has committed to work with Rio Tinto on this challenging opportunity. The proposed machine is a very promising new concept based on a combination of well proven methods and components. This innovative combination is a key reason for selecting Atlas Copco as one of the two suppliers to work with on new tunneling methods for our future block cave operations.”
