The depletion of shallow ore deposits is pushing the mining industry toward deeper underground operations, where efficient rock breakage remains a critical challenge. This thesis develops a mainly geotechnical, data-driven blast design framework for sublevel stoping in Boliden’s Kankberg mine in northern Sweden. By combining established empirical methods with innovative computational approaches such as fuzzy logic, which handles uncertainty and variability much better and is ideal for subjective variables such as rock mass properties. This study enhances Lilly’s Blastability Index and integrates Measurement While Drilling (MWD) data as a real-time proxy for in situ rock behaviour to complement and indirectly validate traditional blastability assessments. Site-specific geological and geotechnical data, together with laboratory tests, inform the development and calibration of this blasting framework. The results demonstrate the potential of the proposed Fuzzy Blastability Index (FBI) and the MWD rock factor to guide theoretical opening slot adjustments, with the intention of optimising slot raise design and reducing overall
drilling costs. The methodology proposes a robust feedback loop between design and operations, contributing to a more scientific approach to underground drilling and blasting. Ultimately, this research offers a transferable approach for a next-generation blast design support tool in underground stope blasting. Although large-scale field validation is still required, the framework establishes a foundation for smarter, real-time design practices for the Kankberg mine. ... Read more

This multidisciplinary report explores the transition potential of the Phalaborwa region, South Africa, from a mining-focused economy to one that integrates sustainable water, energy, and food (WEF) systems in a post extractive setting. Set within a semi-arid climate with significant resource challenges, the study assesses WEF capacities to propose strategic, sustainable development solutions. Analysing critical issues like water scarcity, renewable energy potential, and soil management, the study presents frameworks for sustainable agriculture, water management, and energy solutions to support post-mining economic resilience. Through a multidisciplinary methodology that integrates engineering assessments and urban planning, the report addresses critical biophysical resource issues. The findings emphasize the region’s unique resource inter dependencies, outlining frameworks for post-mining development that strengthen resilience to climate pressures and resource limitations. Ultimately, this study provides actionable insights for creating a balanced, sustain able future for Phalaborwa and the surrounding area. Although the study proposes frameworks that could inform similar transitions in other semi-arid, resource-constrained regions, it also emphasizes the importance of addressing the unique complexities of each area to ensure that solutions are appropriately tailored. ...
