介绍了矿井内的煤尘和湿度分布状况,利用自建的煤尘和湿度实验系统对红外瓦斯传感器进行了煤尘和湿度的影响实验,得出了煤尘对红外瓦斯传感器的影响呈线性的规律和湿度在一定时间内对红外瓦斯传感器的影响也呈线性规律的重要结论,初步建立了煤尘和湿度对红外传感器的实验模型。 This paper introduces the distribution of coal dust and humidity in the mine. Experiments on the effects of coal dust and humidity on the infrared gas sensors are carried out by using the self-built coal dust and humidity experimental system. The results show that the influence of coal dust on the infrared gas sensors is linear The law and humidity in a certain period of time on the impact of infrared gas sensor is also an important conclusion of the linear law, the initial establishment of an experimental model of coal dust and humidity on the infrared sensor.
