A Safety-Constrained Multi-Objective Optimization Framework for Autonomous Mining Systems
This paper presents a scalable, hierarchical autonomous mining architecture, integrating sensor fusion, edge intelligence, fleet coordination, and digital twin-based decision support. It is specifically designed for challenging environments like GNSS-denied conditions and extreme Nordic climates. The framework formalizes vehicle dynamics, drilling mechanics, and multi-agent fleet coordination into a safety-constrained multi-objective optimization problem.
Validated through Monte Carlo simulation, the results show significant improvements over typical baselines: productivity increased by 24.3% ± 3.2%, energy consumption decreased by 12.8% ± 2.5%, and safety risk reduced by 48.6% ± 4.1%. Key performance drivers identified include localization accuracy, communication delay, and optimization weighting. This framework offers a reproducible and transferable reference model for next-generation intelligent mining systems.

Nordic Mining Context: Real-World Resilience
The framework is specifically designed for Nordic mining environments, addressing unique challenges such as GNSS-denied conditions, sub-zero temperatures (down to -30 °C), poor visibility, and stringent regulatory compliance. Autonomous LHD systems achieve ±10–20 cm navigation precision in confined spaces, reducing cycle times by 12–18%. Real-time geotechnical monitoring reduces ground instability risks by about 30%, and emergency response time is cut from 5–10 minutes to 1–3 minutes. This robust design ensures operational continuity and safety in extreme conditions, aligning with the practices of leading Swedish mining companies like LKAB and Boliden.
