Although blasting consumes only ~2% of total mine energy, comminution accounts for 37–53%, making optimised blast design the highest-return energy lever across the entire production chain. The Mine-to-Mill (M2M) approach, supported by fragmentation models (Kuz-Ram) and comminution energy models (Bond Work Index), quantitatively demonstrates that well-designed blasting, controlling powder factor, burden, spacing, and explosive type, can reduce specific energy consumption in comminution by up to 29%, increase mill throughput by 20%, and generate operational savings of tens of millions of dollars per year. Latin America, holding ~40% of global copper and ~35% of lithium production, and where energy represents ~33% of mine operating costs, faces an urgent and strategic need for this transformation. However, its implementation demands professionals trained with a systemic pit-to-plant vision, a perspective that traditional curricula consistently fail to provide. This paper argues that Innovative Education in rock blasting, structured on Education 4.0 principles, active learning, PBL/CBL methodologies, digital technologies, and industry–academia partnerships, is the essential catalyst for this transformation. A competency matrix, five pedagogical dimensions, and an applied framework are proposed for training the mining engineer of the future, capable of integrating technical blasting expertise, artificial intelligence, energy management, and sustainability into cohesive operational decisions.
