2205 of risk, despite the overall decrease in total incidents, reinforces the need to strengthen ground support controls and supervision based on the identification of zones with high geological complexity. At Compañía Minera Poderosa, where safety is established as a core corporate value, microseismic monitoring systems are already implemented as part of the geomechanical control framework. These systems provide valuable information on rock mass behavior and seismic activity associated with mining-induced stress redistribution. However, the current operational practice relies primarily on daily reports, which limits the capacity for immediate response to rapidly evolving geomechanical conditions. As a result, the potential of microseismic monitoring as a realtime preventive safety tool remains underutilized. An industry-wide survey conducted as part of this initiative confirmed that, despite the widespread use of microseismic monitoring, no operational systems currently provide real-time alerts directly accessible to underground personnel. This identified gap motivated the development of the Microseismic Traffic Light System, a pioneering solution designed to integrate continuous microseismic event data with the existing SCADA (Supervisory Control and Data Acquisition) platform, hereafter referred to as SCADA throughout this paper. The system visually represents geomechanical risk levels through an intuitive traffic light scheme (green, yellow, and red), displayed directly within operational work areas. This approach enables personnel to identify increasing risk levels before the occurrence of major instability events, supporting rapid decision-making and proactive safety actions, thereby supporting preventive risk management practices by enabling timely operational responses to changing geomechanical conditions. The proposed system represents a paradigm shift in geomechanical risk prevention, transforming microseismic data into actionable information and establishing a new benchmark for preventive safety management in underground mining. 2. OBJECTIVES 2.1. GENERAL OBJECTIVE To demonstrate the impact and effectiveness of a real-time visual and audible alert system as a key tool for proactive and safe geomechanical risk management in underground mining operations. 2.2. SPECIFIC OBJECTIVES • To verify continuous and stable real-time integration between the SQL-based microseismic database and the existing SCADA system (Supervisory Control and Data Acquisition). • To evaluate the performance of the implemented traffic light–style visual interface by analyzing its effectiveness in communicating microseismic risk levels based on event location and magnitude. • To supervise the operational status of visual and audible alert devices installed at strategic underground locations, ensuring their contribution to preventive personnel response. • To analyze the results of the pilot implementation, incorporating workforce feedback to validate system effectiveness and to define guidelines for optimization and potential scaling.
