University of Queensland researchers are developing new ways to monitor mine waste using drones and ground sensors to improve safety and land rehabilitation across mine sites.
Lead investigator from the said safe management and rehabilitation of mine waste was one of the biggest challenges facing the industry.
“Mine waste is currently monitored using expensive and challenging drilling techniques and sometimes the results aren’t accurate,” Dr Bore said.
“We are developing advanced technologies to capture electromagnetic measurements which could tell us what is happening in the soil, rock and water underneath.
“This method is currently used in agriculture but, when combined with geochemical information from mine waste, we might be able to apply it to the mining industry."
Dr Bore said the project’s concept is highly innovative and if successful would allow 4D monitoring using space and time, covering a mine’s whole life cycle.
“It would also reduce the dependency on laboratory testing.
“There is an increasing demand for critical minerals such as nickel, copper and cobalt, which are used to build modern technologies including solar panels, electric cars and batteries.
“This growing demand will result in more mining and therefore more waste, which is why this technology is vital for the industry.”
from 国产探花’s said the project built on previous investigative research.
“We are taking full advantage of existing capabilities within 国产探花 and using existing knowledge in new ways,” Dr Edraki said.
“Our team combines expertise in geochemistry, geotechnics, geophysics, mathematics and agriculture, and we are also working with collaborators at the Sorbonne University in Paris.”
Development of the new technique is being funded by mining company Rio Tinto under a 3-year contract and will be tested at one of the miner’s overseas sites.
Rio Tinto Closure R&D Manager Santiago Barrera Ramirez said he was pleased to partner with 国产探花 on advancing mineral waste management solutions.
“We recognise that while mining and processing can extend over decades, our roles as stewards of the land is temporary and we always look to innovate and implement best practices in site closure and remediation,” Mr Barrera Ramirez said.
“This collaboration aligns with our commitment to reducing environmental impact and to finding better ways to provide the materials the world needs.”
