Title

Fire-Extinguishing and Explosion-Suppression Technology for a Super-Large and Shallow Working Underground Fire Zone

Abstract

The Baijigou Mine fire in Ningxia Province, which broke out on October 24, 2003, affected more than 10 Mm3 of the mine and was probably the largest underground fire in China in recent years. In addition to its size, the fire was also characterized by excessive air leakage and potential for violent methane explosions. A series of new measures were employed to fight the fire, including sealing intake tunnels with water, injecting three-phase foam through boreholes, and flushing with a large volume of nitrogen. The fire was successfully extinguished and production resumed soon afterwards; not one single methane explosion occurred during fire-fighting and afterwards. © 2006 Taylor & Francis Group.
