摘　　要：瓦斯是在煤炭开采作业中的危险气体,对煤矿井下的瓦斯等易燃易爆气体实时监控报警是确保煤矿生产安全的重要工作。光学监测技术具有无损快速的特点,且可以结合光学通讯实现井下无源探测。本文以华阳集团新景矿15232工作面为研究对象,基于可调谐二极管激光吸收光谱技术,研发了一套针对甲烷等易燃易爆气体的远程监测系统,实现对煤矿井下2000 m外的气体环境进行精准、实时的监测。经过实践,该方法具有很好的准确性,相比传统束管系统,实现了气体监测的快速分析,监测采样频率更高,提高了新景矿井下有害气体的监测水平。Gas is a dangerous gas in coal mining operations.Real-time monitoring and alarming of flammable and explosive gases such as gas in coal mines is an important work to ensure the safety of coal mine production.Optical monitoring technology has the characteristics of non-destructive and fast,and can be combined with optical communication to achieve underground passive detection.In this paper,the 15232 working face of Xinjing Mine of Huayang Group is taken as the research object.Based on the tunable diode laser absorption spectroscopy technology,a set of remote monitoring system for flammable and explosive gases such as methane is developed to realize accurate and real-time monitoring of the gas environment 2000 m away from the coal mine.Through practice,this method has good accuracy.Compared with the traditional beam tube system,it realizes the rapid analysis of gas monitoring,and the monitoring sampling frequency is higher,which improves the monitoring level of harmful gas in Xinjing mine.
