摘　　要：KJ90煤矿监控系统在松藻煤矿现场使用过程中,由于监控设备、传输线路以及人为等因素,造成煤矿井下被监控地点的实际瓦斯数值没有达到超限报警值,但却发生了瓦斯误报警的现象。根据历史瓦斯监测曲线,从不同角度进行分析造成监控过程中出现瓦斯误报警现象的原因,同时提出有针对性的对策措施,为煤矿现场的安全生产提供了有力的保障。In the application of K J90 type coal mine monitoring system in the Songzao Coal Mine, due to the factors of monitoring equipments, transmission lines and artificial destruction, the phenomenon of gas false - alarming is found when the actual gas emission at underground monitoring site does not reach the off - gauge alarm numerical values. According to the historical gas monitoring curve, the reasons lead to the gas false - alarming phenomenon are analyzed from different angles, at the same time, some targeted countermeasures are put forward, which provides a strong guarantee for safety production in coal mine.
