and reduce cable lengths. In addition, a detailed field scan was conducted to obtain the exact dimensions of the mobile substations, confirming a footprint of approximately 19 × 6 m. This information supported the redesign of specific benches to safely accommodate the substations and to position them closer to lower benches. 3.3.10 Cable Length Estimation Approximate trailing cable requirements were calculated for each alternative as a comparative variable between scenarios. 3.3.11 Scenario Development and Interdisciplinary Review 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.
