摘要
为彻底根治山西大同忻州窑矿东三盘区火灾隐患,在该矿8516下工作面回采期间发生CO浓度超限后,根据现场情况分析了CO浓度超限的具体原因。针对回采期间对CO超限进行治理后,依然有CO涌入工作面的情况,提出对工作面进行封闭的措施,并对设备回撤期间及封闭后的防灭火措施进行了详细分析,通过采取注氮、黄泥灌浆、地面裂缝充填等一系列防火技术措施进行治理,CO气体浓度为1×10^(-6),防灭火效果显著。
In order to eradicate fire hazard of Shanxi Tongxinyao Mine, based on CO concentration overrun in 8516_下working face recovering mining, with CO overrun after control, the working face was blocked, fire preventing and extinguishing measures were analyzed, Nitrogen injection, yellow mud grouting and surface fracture filling were adopted, CO gas concentration declined to 1 mmp after control, with obvious fire-fighting effect.
