摘要: 针对矿井现有瓦斯传感器布置主要为瓦斯爆炸、瓦斯积聚等灾害监测而布置，而非为监测工作面瓦斯涌出特征而布置的情况，探讨了一种工作面瓦斯传感器的位置布置方案。试验结果表明，将传感器布置在距离工作面5 m左右的距离，其监控数据较为符合工作面真实的瓦斯涌出情况，满足监测工作面瓦斯涌出特征的需要；矿井现有的掘进工作面迎头瓦斯传感器布置方式能满足监测工作面瓦斯涌出特征的需要。

Abstract: For situation that existing mine gas sensor is mainly used for monitoring disasters of gas explosion and gas accumulation, and not for monitoring gas emission characteristics of working face, the paper discussed a kind of layout scheme of gas sensor. The test results show that the sensors lay out 5 m distance far from the working face, the monitoring data conform to the real gas emission monitoring of working face, and meet needs of monitoring gas emission characteristics. Current arrangement of gas sensor on head-on of heading face can meet needs of monitoring gas emission characteristics.
