Efficient Earth Observation System for Acid Mine Drainage
Original language description
Acid Mine Drainage (AMD),a significant water pollutant from sulfide mineral oxidation in mining areas, generates sulfuric acid and harmful substances. Effective AMD management involves careful material handling, treatment, and water management. Imaging spectroscopy provides a practical alternative to traditional chemical analysis, identifying pyrite oxidation "hot spots" and sulfate mineral formation. This research develops robust AMD monitoring systems using machine learning techniques on optical multi- and hyperspectral data. We use hyperspectral (PIKA L camera, UAV) and multispectral (Sentinel-2, orbital) datasets at the Litov post-mine dump (Sokolov lignite basin, Czech Republic). Validated against XRD mineralogy and Google Earth-identified hotspots, Radial Basis Function Support Vector Machine (RBF SVM) outperforms other ML methods in identifying AMD hot spots and class separation. RBF SVM effectively detects AMD discharge and distinguishes mineral mixtures (oxy-hydroxides and oxides) using both Pika L and Sentinel-2 data.
