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 significant number of low-magnitude events, which may affect statistical consistency and hazard interpretation within the monitored zone. Figure 3 presents the Gutenberg–Richter frequency–magnitude analysis used to estimate the b-value after applying the magnitude of completeness criteria, enabling a more representative characterization of the seismic response of the rock mass. Figures 5 to 7 present the field deployment of the traffic light system, including the installation of control panels and visual/audible beacons used for real-time communication of geomechanical risk underground. 4.3. Discussion The results demonstrate the effectiveness of transforming microseismic data into real-time actionable alerts; however, several considerations remain for broader implementation. From an operational perspective, scalability depends on the availability of a sufficiently dense 64
