Study of the Fire Behavior of Multilayer Cables in a Mine Tunnel

Fires caused by cables occur frequently in mines, which endanger the safety of workers. To explore characteristics a multilayer cable fire mine tunnel, simulations were carried out using Fire Dynamics Simulator (FDS). The influence tray spacing, ignition position, and tunnel ventilation speed on studied. results showed that these factors change amount contact between air, heat accumulation, transfer flame interaction cables. It was also noted increasing spacing or wind both made peak release rate (PHRR) initially increase then decrease. burnout upstream downstream sides source not consistent, had sensitive effect burn side source. higher position was, longer arrival time PHRR slower developed. There velocity close to ceiling. hooks obstructed fire. This study provides theoretical basis for prevention control tunnels.
