2208 • Transmission Network: The corporate network infrastructure ensures uninterrupted, realtime data transmission and processing without the need for manual intervention. This integrated architecture provides operational personnel with clear, actionable alerts, significantly strengthening preventive capacity and improving safety performance in underground mining environments. 4. PRESENTATION AND DISCUSSION OF RESULTS The implementation of the real-time microseismic traffic light system provides a practical framework to address limitations associated with delayed interpretation of seismic data in underground mining operations. By integrating continuous microseismic monitoring into operational workflows, the system enables direct and immediate communication of geomechanical risk at the working face. This approach represents a transition from a reactive, report-based model toward a preventive and operationally accessible system, where risk information is translated into actionable alerts for underground personnel. The integration of automated processing and real-time visualization allows for improved situational awareness under dynamic geomechanical conditions, particularly in zones characterized by elevated microseismic activity. 4.1. System Operation and Deployment The system was deployed in underground sectors characterized by elevated microseismic activity, operating continuously under real-time conditions. The architecture described in Section 3.5 enabled the integration of sensing, data processing, and alert communication within daily mining operations. During operation, microseismic events exceeding predefined thresholds triggered immediate visual and audible alerts at the working face, allowing personnel to identify risk levels without requiring specialized interpretation. The traffic light logic (green–yellow–red) facilitated rapid situational awareness under dynamic geomechanical conditions. The system maintained stable performance throughout the monitoring period, ensuring uninterrupted data transmission and consistent alert activation. Operational personnel were able to interact with the interface to monitor event evolution and support real-time decision-making. This deployment demonstrated the capability of the system to function as an operational tool, bridging the gap between microseismic monitoring and immediate risk response in underground mining environments. Figure 5 illustrates the installation of the traffic light control infrastructure along the monitored underground section, enabling real-time transmission and activation of visual alerts. Figure 7 shows the visual and audible beacons installed underground, which provide immediate traffic light alerts to operational personnel under dynamic geomechanical conditions. 4.2. Pilot Implementation and Performance Evaluation The system was deployed in underground zones characterized by historically high microseismic activity to validate its performance under operational conditions. The pilot implementation was conducted over a continuous monitoring period of 30 days and included full hardware installation, system integration, and real-time operation. Performance evaluation was based on predefined criteria, including: • Detection speed, measured as the time between event occurrence and alert activation; • Alert accuracy, defined as the correct activation of alarms for events exceeding established thresholds; • System stability, evaluated through continuous operation without interruptions; and • User response time, assessed based on the reaction of personnel to visual and audible alerts. Alert thresholds were defined using cumulative energy analysis and Gutenberg–Richter statistical parameters, ensuring consistency with observed microseismic behavior in the monitored zones. As shown in Figure 2, the initial distribution of recorded microseismic events includes a
