连续自动监测矿井巷道空气中 CO 含量是早期发现煤自燃而使用的最普遍的方法。为此,现在一般都使用 CO 气体分析仪。这种仪器的作用原理是根据多数气体都能够选择性的吸收红外线辐射带的能量。СИГМА—CO—B 型微浓度 CO 自动气体分析仪就是这种同类用途的仪器,它是由煤炭生产过程自动化设计院和全苏矿山救护科研院第聂伯彼得罗夫斯克分院共同研制的。该仪器在1988年已由科诺托
Continuous and automatic monitoring of CO in the air of coal mine roadway is the most common method used to detect coal spontaneous combustion in the early stage. For this reason, CO gas analyzers are now generally used. The principle of this instrument is based on the majority of gases are able to selectively absorb the energy of the infrared radiation band. The СИГМА-CO-B Micro Concentration CO Automated Gas Analyzer is the same instrument of its kind developed by the Coal Production Process Automation Design Institute and the Dnepropetrovsk Branch of the All-Russian Mine Ambulance Research Institute. The instrument was supplied by Konotto in 1988
