• Holes per Shift (H_shift): Completed holes in a 12-hour shift (holes/shift) • Monthly Production (P_month): Total completed holes per month (holes/month) Stage escalation required reduced variability and sustained stability of time-based KPIs relative to manual baseline performance across consecutive drilling grids. In addition to operational indicators, safety and organizational readiness were incorporated as structured validation dimensions. Safety validation focused on documented reduction of direct operator exposure through physical separation enabled by tele-operation and verification of predefined fail-safe responses under degraded communication scenarios. Organizational validation considered supervisory adaptation, stabilization of manual intervention frequency, and completion of structured training checkpoints prior to progression to higher autonomy levels. 3. Execution Strategy The execution of the proposed methodology was managed as an integrated operational deployment rather than a purely technical rollout. The execution strategy translated the conceptual framework of autonomy levels, technical architecture, and safety-by-design principles into concrete field actions, procedures, and organizational practices. Execution activities were structured to ensure that each autonomy level and architectural capability introduced during implementation was validated under real operating conditions before progressing to more advanced stages. 3.1. Integrated Operational Deployment Operational deployment was executed under active production conditions through coordinated integration of technical infrastructure, digital supervisory environments, and validated communication architecture. A mobile control station enabled remote supervision and operational control while ensuring physical separation between the operator and the drilling equipment. The control environment integrated multi-camera visualization, fleet management interfaces, real-time condition monitoring dashboards, and digital drilling pattern loading tools, providing comprehensive situational awareness for supervisory decision-making. Interconnection between onboard drill control systems and remote interfaces was supported by a validated communication architecture ensuring stable data exchange and predefined fail-safe responses under degraded scenarios. Deployment progressed incrementally in alignment with controlled production schedules. System functionality was validated at each stage to confirm stable drilling execution, reliable supervisory response, and integration with site-level operational systems. This structured deployment approach enabled controlled escalation toward higher autonomy levels while maintaining production stability.
