Underground mine fires are a significant hazard that can threaten the safety and continuity of mining operations. This study aims to determine the impact of ventilation systems and ventilation doors on fire scenarios in an underground gold mine. The fire locations considered are the haulage route, caused by a diesel engine Light Vehicle (LV), and DD04, caused by a 110 kWh electric drill. The fire simulations lasted for one hour and were not conducted simultaneously at both locations. The HRR generated by the diesel engine vehicle and the electric drill were 1454.33 kW and 4554.61 kW. Simulation results using Ventsim Design 6.0 software indicate that scenarios involving deactivating the ventilation system and closing ventilation doors during a fire can result in significant increases in temperature and carbon monoxide gas levels at the fire location. The maximum temperatures in the haulage route and DD04 when the ventilation system was turned off were 288.38°C with an HRR of 1352 kW and 318.32°C with an HRR of 4395.45 kW. In these simulations, the HRR produced was lower because the air supply to the vicinity of the fire scenario was more limited without sufficient ventilation. The forcing ventilation system increased the heat release rate to 4944.11 kW and resulted in lower temperatures. Based on the simulation results, factors influencing the temperature in fire scenarios is quantity of fuel. HRR is influenced by the amount of oxygen provided by the existing ventilation system.
