Abstract:
Mine closure demands multidomain, temporally resolved data, yet conventional workflows leave these datasets fragmented and underused when decisions must be made. The Bio+Mine Digital Twin project, based on work carried out at the Sto. Niño legacy mine site in the Philippines, will address this by integrating data from 4 domains into an interrogable data cube from which artificial intelligence (AI) and machine-learning tools can identify cross-domain relationships and model site trajectories through time. A central aim is to establish where cheaper proxies can substitute for intensive sampling. Because the method and learned relationships will be recalibrated to each new site, the outcome will be a modular, transferable workflow template that supports consistent, evidence-based closure practice.
