摘要
痕迹示踪气体的精确检测是煤矿内因火灾监测预警的关键环节,目前没有1×10-9级别的示踪气体精确定量检测设备,提高检测装备的精度是提升煤矿内因火灾预警效能的有效途径,研究了腔增强吸收光谱检测技术,得到了煤矿六氟化硫示踪气体的精确在线检测方法,为煤矿内因火灾致灾因素的分析、预警提供了新思路、新方法。
The accurate detection of tracer gas is the key to the monitoring and early warning of coal mine internal fire,there is no precise quantitative tracer gas detection equipment with the level of 1 × 10-9,the accuracy improvement of detection equipment is an effective way to enhance the effectiveness of coal mine internal fire warning. The cavity enhanced absorption spectroscopy detection technology is studied,it is obtained that the precise online detection method for coal mine sulfur hexafluoride tracer gas,which provides new ideas and new methods for causal factors analysis and early warning of coal mine internal fire.
