摘　　要：近年来受到国民经济快速发展的推动,煤矿的开采量和消费量呈现快速增长的势头,同时很多煤矿企业存在着安全监测不完善等煤矿安全问题,严重影响了煤矿的开采和人员的安全,其中瓦斯监控是煤矿安全中的重要组成部分。介绍了一种基于非分光红外原理的瓦斯传感器的工作原理,同时阐述了压力补偿的必要性,然后基于最新的单光源双通道甲烷传感器进行分析,介绍了一种压力补偿方法,基本克服了压力的漂移问题,提高了测量的准确性。In recent years , the rapid development of national economy improves the production and consumption of coal mine . At the same time , there are lots of security issues which seriously affected the coal mining and personnel safety . In the safety monitor-ing , methane measurement is the most important . This paper describes the principle of methane transducer based on non-dispersive infrared and the necessity about pressure compensation . Using methane sensor which based on dual-channel and single source , de-scribe the method of it , basically overcome the problem of temperature pressure drift , increase the measurement accuracy .
