Dig deeper with our mining equipment forecasts

As ore mines ramp up and come on stream, the total number of active surface machines (including trucks, excavators, shovels, loaders, graders and dozers) is forecast to rise from 141,470 in 2020 to 167,367 by 2025. This will be a CAGR of 3.4% from 2020 to 2025. The largest contributor to this growth is expected to be trucks, particularly smaller-sized trucks with shorter lifespans, used extensively in parts of Asia Pacific. Underground mining equipment is similarly expected to see a CAGR of 2.3% in this same time frame, with the number of mining trucks and loaders/LHDs in active underground mines expected to rise to 19,853 by 2025. GlobalData’s extensive mine-site research and equipment models have been used to build a complete view of mobile mining equipment populations globally for trucks, loaders, graders, dozers, excavators and shovels.

Currently, inspection of the mining complex is being conducted with the local emergency services as well as Utah’s Department of Transportation.

Rio Tinto Copper & Diamonds chief executive Arnaud Soirat said: “The safety of our employees and wider community is our first priority and having ensured that all our employees are safe and the operations are shut, we are now working with the local emergency services and regulators to ensure the asset is safe before resuming any operations.”

In December last year, Rio Tinto said that it is set to continue Kennecott copper mine production with an investment of $1.5bn over a period of six years.

Earlier this week, measures put in place by Mongolian authorities to contain the spread of the Covid-19 outbreak have restricted operations at Rio Tinto’s Oyu Tolgoi mine, causing a slowdown in production.

Last month, Rio Tinto said it was facing a slowdown in copper concentrate shipments from Oyu Tolgoi copper and gold mine as efforts to contain the Covid-19 outbreak affected the company’s product flows to China.
