Inert Technology Application for Fire Treatment in Dead End Referred to High Gassy Mine
The fire accident of the return airway for 7th mining area in TaoYi occurred in the middle section of the dead-end roadway referred to high gassy mine, which is difficult to handle and the technology request is high. Based on analysis of accident characteristics, a technology solution related to inerting and asphyxia was put forward, which combined the methods of underground injecting the inert gases into the fire area with the method of overground injecting the nitrous. After the injecting, the concentration of oxygen in the fire area reduced and the gas was asphyxial, which eliminated the danger of gas explosion and avoided expanding the accident. The successful application of this technology can provide references for the treatment of other similar fire accidents.
