Using driverless trucks in underground mines is the next focus for the Queensland mining industry.
As the sector looks for greater productivity and efficiency, a major research project to develop automation technologies for underground mining vehicles will soon get underway.
Work is about to begin on developing technologies to automate underground mining vehicles, after the State Government announced more than $400,000 in funding for the project.
It is possible that within the next five years, the sound of key in ignition may no longer exist in Queensland’s underground mining industry.
Dr Thierry Peynot will be involved in the project.
While driverless mine trucks are not a rarity, particularly in Western Australian mines, they operate above ground with GPS.
Dr Peynot said one of the big issues researchers faced in developing driverless underground mine vehicles was the harsh environment, while also navigating the machinery through a maze of dark tunnels.
He said the team would focus on developing camera-based positioning systems for locating and tracking underground mining vehicles, as well as multi-sensor systems for accurate positioning.
“The vision technology is going to be the core of that project [and] it is looking at recognizing places that it [the vehicle] has been before,” Dr Peynot said.
“Usually we have complex maps of the mines available, and it is about knowing where that vehicle is in that map.
“What we can do is navigate one vehicle with one camera around the mine first, once, and then we can recognize where we have been once we come back to the same place.
“There will be some changes in the mine obviously, but we can accommodate for that by recognizing all the things that did not change from the first passage.”
What is the benefit of driverless trucks?
Those steps will eventually lead to driverless vehicles working underground.
Dr Peynot believed autonomous machinery would save the underground sector time and money.
Mine safety may also be enhanced.
“If you can localise precisely the vehicles in the mine, then you can improve safety, and once they are automated, you can remove people from the dangerous areas and have them monitor from the outside,” Dr Peynot said.
“In terms of productivity, if you can localise those vehicles precisely, then you can do two things — you can analyse the process better, and how to best use them from what they are doing at the moment.
“Later down the track you can really optimise the spaces between the vehicles and when one vehicle should do what.”
The project is expected to run for two years in partnership with international mining equipment manufacturer Caterpillar.
