2050 Two primary scenarios were developed: optimizing the location of mobile substations within the existing mine design and implementing localized adjustments to waste bench geometry to position electrical infrastructure closer to active operational phases. Both scenarios were collaboratively reviewed with the electrical maintenance, geotechnical, mine operations, and planning teams to ensure technical feasibility, operational safety, and alignment with long‑ and short‑term planning objectives. 3.3.12 Strategy Selection and Implementation The final strategy was defined through interdisciplinary collaboration and subsequently integrated into weekly, quarterly, and medium-term planning cycles for continuous monitoring and implementation. This is not a one‑time exercise, but an iterative process that evolves as mine plans are updated. Each revision of key planning horizons requires alignment with how electrical infrastructure will adapt to these changes. It is recommended that this approach be integrated into the mine planning cycles: quarterly, annually, and at least up the five year horizon. Accordingly, topographic data, infrastructure locations, and supporting inputs must be periodically updated. However, beyond this regular update cycle, which is already part of standard mine planning practice, no significant additional effort is required. In essence, the process involves routinely requesting updated information, integrating it, identifying viable solutions, validating them with the relevant stakeholders, and incorporating the outcomes into the updated mine plans. 4. KEY RESULTS, OUTCOMES, OR INSIGHTS The early incorporation of constraints such as maximum catenary spacing, blasting impact radii, and geotechnical requirements enabled power supply to be integrated into the planning process, reducing future conflicts between phase advancement and the positioning of critical infrastructure. The five‑year horizon analysis allowed major electrical system reconfigurations to be anticipated, while the evaluation of long‑term period maps demonstrated that changes in ramp orientation and phase sequencing can invalidate initial pole and substation locations if not considered early, highlighting the need to embed electrical criteria within strategic mine planning. Optimization of mobile substation positioning improved overall operational efficiency. Relocating substations closer to active mining areas, while respecting safety and spatial constraints, reduced supply distances, improved power quality, and enhanced the operational continuity of electric rope shovels. In addition, prioritizing straight and accessible alignments facilitated maintenance, minimized interference with mine traffic, and simplified future system expansions. The interdisciplinary collaborative process was a key enabler in selecting the final scenario, as joint reviews with electrical maintenance, geotechnical, mine operations, and planning teams ensured that solutions were validated not only from a technical perspective but also from operational and constructability standpoints. 5. CONCLUSIONS AND IMPLICATIONS FOR INDUSTRY This study demonstrates that electrical infrastructure should be treated as a core design variable rather than an afterthought in open pit mine planning. Integrating medium-voltage reticulation (13.8 kV / 7.2 kV) into mine design and sequencing, rather than managing it as a reactive support system, reduces unplanned relocations, trailing-cable runs, and post-blast re-energization delays, while improving shovel utilization and overall planning reliability. A structured five-year planning horizon supported by period maps enables early identification of ramp reorientations, phase interactions, and potential conflicts between blasting activities and electrical infrastructure, including poles, overhead lines, and mobile substations.
