Ventilation Map

This report documents a series of emergencies within the mine, including a significant fire affecting multiple entries, air quality concerns with high levels of carbon monoxide and nitrogen dioxide, and impassable conditions caused by caving. The situation includes a thorough review of airflow metrics, smoke levels, and combustion gases, as well as urgent safety measures undertaken, such as the deployment of fire suppression equipment and ventilation adjustments in various sections, including Entry 3 and the East Decline.
