Imaging Legacy Mine Wastes: Geoelectrical Characterisation of Tailings and Waste Rocks in the Philippines and the UK

Cris Reven Gibaga, Russell Swift, Gawen Jenkin, Jonathan Chambers et autres

Legacy mine wastes have accumulated over centuries in regions such as Benguet, Philippines, and Cornwall, United Kingdom. Inefficient historical processing left valuable metals in these materials, supporting their potential role in a circular economy through secondary resource recovery. However, elevated concentrations of …

Just how wet is it? Defining resistivity / moisture content relationships in African Alfisols

Russell Swift, Jonathan Chambers, I. Sandram, T. Mtangadura et autres

A key parameter influencing crop growth is the availability of water and its spatial distribution within agricultural soils. The strong electrical response associated with variations in water content means that electrical geophysical methods such as Electrical Resistivity Tomography ( ERT ) are …

High-resolution geophysical monitoring of moisture accumulation preceding slope movement—a path to improved early warning

Arnaud Watlet, Paul Wilkinson, Jim Whiteley, Adrian White et autres

Abstract Slope failures are an ongoing global threat leading to significant numbers of fatalities and infrastructure damage. Landslide impact on communities can be reduced using efficient early warning systems to plan mitigation measures and protect elements at risk. This manuscript presents an …

Sustainable mining in tropical, biodiverse landscapes: Environmental challenges and opportunities in the archipelagic Philippines

Justine Perry T. Domingo, Gawen R. T. Jenkin, Laura Quick, Richard Williams et autres

The rising demand for critical metals presents a major economic opportunity for mineral-rich countries. For a sustainable transition to a low-carbon future, it is essential to minimise impacts of mineral resource development to the environment, ecosystems, and societies of these nations. Although …

Assessment of railway infrastructure slope failure by automated time-lapse ERT monitoring

Zeynab Maleki, Paul Wilkinson, Russell Swift, Philip Meldrum et autres

This study underscores the need for subsurface imaging and monitoring techniques to offer timely information on railway embankment condition and to contribute to the decision-making processes needed to minimise the risks of catastrophic slope failure. We investigate electrical resistivity tomography (ERT) as …

Long-term geophysical monitoring of safety critical geotechnical infrastructure slopes

Jonathan Chambers, Paul Wilkinson, P.I. Meldrum, O. Kuras et autres

Robust and timely assessment of the condition of geotechnical infrastructure assets (e.g. cuttings, embankments, dams) is essential for cost effective maintenance and engineering interventions to prevent failure events. Infrastructure slopes (in transportation, utilities and water management) are experiencing increasingly high levels of …

Integrated geophysical-geodetic-geotechnical systems for slope-scale landslide monitoring

Jonathan Chambers, James Boyd, Paul Wilkinson, Philip Meldrum et autres

Moisture induced landslides in clay slopes are generally driven by heterogeneity in both saturation levels and material properties and their arising complex and dynamic interactions in the subsurface. The use of time-lapse geophysical imaging can illuminate four-dimensional subsurface moisture dynamics and geotechnical …

Recent developments in the science and technology of in situ solvent leaching of tailings for reprocessing, rehabilitation and closure

Gawen Jenkin, Carlo A. Arcilla, Andrew P. Abbott, Luke Bateson et autres

Tailings storage facilities pose environmental hazards and their failure can cause contaminated materials to be released, affecting people and ecosystems. Conversely, tailings are significant resources of unrecovered metals, especially in older facilities produced using less efficient mineral processing. The already finely ground …

Assessing the risk of slope failure to highway infrastructure using automated time-lapse electrical resistivity tomography monitoring

Jim Whiteley, C. Inauen, Paul Wilkinson, Philip Meldrum et autres

Electrical resistivity tomography (ERT) monitoring provides time-lapse images of the subsurface. These images can be used to assess spatiotemporal variation in moisture content, which is a key driver of slope failure, making ERT monitoring an effective tool to evaluate precursory conditions of …
