| 摘 要： | 分析了半导体激光吸收光谱技术监测气体浓度的基本原理,根据采空区煤自然发火的特征,采用气体分析法设计了一种基于激光气体分析的矿井火灾预警系统。依据煤自燃过程中各阶段释放标志性气体不同的特点,以及采空区三带静态分布的理论,给出了定性和定量判断采空区煤自然发火状况的判定方法,为矿井安全奠定了基础。

| Abstract: | The principle of gas concentration monitoring with diode laser absorption spectroscopy is given.According to the characteristics of spontaneous combustion of coal mine gob,mine fire alarm system based on a laser gas analysis is achieved by the use of gas detection.Based on the characteristics of different symbolic gases produced in different periods of spontaneous combustion of coal,and the theory of static distribution of three zones,theories are given to make the qualitative and quantitative determine to spontaneous combustion of coal mine gob,laid the foundation for mine safety. |
