摘要:

分析了气体光谱吸收基本原理,研究了一套光纤传感瓦斯系统,应用于某超化煤矿试验,并取得良好效果。指出基于光谱吸收的煤矿瓦斯光纤传感器,可用于对煤矿瓦斯气体进行大范围监测,也可在线连续监测井下瓦斯气体,其具有广阔的应用前景。

关键词: 光谱吸收, 煤矿瓦斯, 光纤传感气体

Abstract:

The basic principles of gas absorption is analyzed.An optical fiber sensing gas system is studied,which has been used in a super test of mine with good results achieved.It is proposed that the coal mine gas optical fiber sensor based on spectrum absorption can be used both for large-scale monitoring of coal mine gas and for continuous online monitoring of underground gas and therefore has broad application prospects.

Key words: spectrum absorption;coal mine gas;optical fiber sensing gas
