矿井火灾初期自动风流控制系统的研究及应用

Research and Application of Auto Air Flow Control System at Initial Mine Fire Accident

矿井火灾是矿井重大灾害之一 ,火灾时期的风流状态控制是处理火灾最重要的任务之一 ,利用定性和定量综合分析法结合火灾特性区间法可为井下工人的安全撤退及火灾处理提供了合适的控风方案 ;文章还介绍了自动防火风门和自动喷淋系统。

During a period of a mine fire, a joint function of a fire and wind pressure occurred at a mine fire accident and mechanical air pressure of the main fan will damage an original balance between a ventilation power and resistance under a normal ventilation condition. Therefore this will make a disturbance of the air flow which could cause a reverse air flow in some mine roadways. The reverse air flow will bring poison gas into the incoming air area, thus the influenced area of the mine fire accident will be increased. Base on such situation, with a comprehensive qualitative and quantitative analysis method and a fire characteristics regional method, the authors have provided asuitable air control plan for underground miners safety running out and mine fire control. The authors have developed an applied remote controlled auto anti-fire door and auto water spraying system. Therefore a ventilation plan and a fire put off method at a fire initial stage were provided for practices. This system is safe and reliable and suitable, and is easy to install and maintained.
