Researchers at the University of Queensland (UQ) are developing innovative methods to observe and monitor mine waste using advanced drones and ground sensors. This project aims to not only enhance safety but also improve land rehabilitation efforts across mining sites, addressing a critical need in the face of growing environmental concerns.

Current mine waste monitoring methods, which rely on expensive and often inaccurate drilling techniques, present significant challenges for mining operations. These methods can lead to inconsistent data, making it difficult to assess environmental risks accurately. The new technology under development at UQ promises to offer a more efficient, precise, and scalable alternative that can significantly reduce costs and improve monitoring accuracy.
The Need for Innovation
The safe management and rehabilitation of mine waste have become critical issues in the mining industry, particularly as the demand for essential minerals like nickel, copper, and cobalt continues to rise. These minerals are vital for modern technologies, including solar panels, electric vehicles, and batteries. However, with increased mining activity comes greater volumes of waste, and traditional monitoring techniques have proven inadequate for reliable, large-scale waste management. There is an urgent need for more cost-effective, real-time solutions that provide a comprehensive understanding of waste dynamics.
The Current Study
Led by Dr. Thierry Bore from UQ's School of Civil Engineering, the research aims to leverage electromagnetic measurements for monitoring the conditions of soil, rock, and water beneath mine sites. This technique, traditionally used in agriculture, is being adapted for the mining industry by integrating geochemical data from mine waste. The project's goal is to develop a 4D monitoring system that tracks temporal and spatial changes throughout a mine's life cycle, minimizing the reliance on laboratory testing.
Results and Discussion
The project builds on existing research and expertise within UQ, utilizing knowledge in fields such as geochemistry, geophysics, geotechnics, and mathematics. The team is collaborating with Sorbonne University in Paris and has secured funding from Rio Tinto for a three-year contract to test the new technology at one of the company’s overseas mining sites. The collaboration with Rio Tinto underscores the mining industry’s commitment to improving waste management practices and reducing environmental impacts.
Conclusion
The development of this advanced mine waste monitoring technology has the potential to revolutionize the way mining sites are managed and rehabilitated. If successful, the project will offer a more accurate, cost-effective, and comprehensive solution for monitoring mine waste, ultimately contributing to better environmental stewardship in the mining sector.
