Geotechnical risk management for critical mining infrastructure, tailings dams, and slopes in general requires monitoring systems capable of detecting instability precursors with continuous spatial coverage and sufficient operational lead time. Conventional methods (inclinometers, piezometers, extensometers, and GNSS) provide only point-based coverage, involve high field maintenance costs, and are subject to access limitations in steep terrain. The failures at Brumadinho (Brazil, 2019; 270 fatalities), Samarco (Brazil, 2015; 19 fatalities), and Mount Polley (Canada, 2014) highlight the catastrophic consequences of deficiencies in early warning systems.
