Based on the theory of optical analysis method of gas concentration Lambert Beer law and spectral gas detection technology development ,this system has realized the advance warning of fire and gas disaster in coal mine ,real-time mon-itoring of toxic or harmful gases and coal mine gas explosion hazard identification ,significant to the coal mine disaster pre-vention and control ,put an end to secondary disaster relief process ,ensure the safety of the lives of coal miners and rescue team and to promote coal mine safety in production .%本系统基于气体浓度光学分析方法理论朗伯-比尔(Lambert-Beer )定律、光谱气体检测技术开发 ,实现了对煤矿火灾与瓦斯灾害超前预警、灾害产生的有毒有害气体实时监测和煤矿环境气体爆炸危险性辨识 ,对于煤矿灾害防治、救灾过程中杜绝次生灾害 ,保障煤矿工人及救护队员的生命安全 ,促进煤矿安全生产具有重要意义.
