一、前言 一九七九年研制了煤矿井下用定电位电解式一氧化碳浓度检测仪,在日本国内迅速的采用了这种仪器,到目前为止已有200多台定电位电解式一氧化碳检测仪投入使用。煤矿井下用的定电位电解式一氧化碳检测仪与过去的非分散式红外线一氧化碳检测仪比较,重量轻、易操作、价格便宜、精度高、安全性也好,可在测定现场移动,特别适用于在广范围的井下使用,因此,今后将会不断增加使用台数。 在煤矿根据一氧化碳的信息反应,可检测造成重大火灾的自然起火,井下火灾,并把其一氧化碳浓度信息传送到井上,再由监视人员观察其记录图表并判断其安全性。但是在煤矿把以一氧化碳为主的甲烷等的安全信息和有关生产信息集中在监视室,来增加 I. Preface In 1979, a fixed-potential electrolytic carbon monoxide detector for underground coal mine was developed and rapidly adopted in Japan. So far more than 200 fixed-potential electrolytic carbon monoxide detectors have been put into use . Compared with the past non-dispersive infrared carbon monoxide detector, the constant potential electrolytic carbon monoxide detector used in underground coal mines is light weight, easy to operate, cheap, high precision and safety, and can be moved on the measurement site, A wide range of underground use, therefore, will continue to increase the number of units in the future. At coal mines, which respond to carbon monoxide information, spontaneous fires and downhole fires that caused major fires can be detected and their carbon monoxide concentration information can be transmitted to the well where they can be observed and recorded by surveillance personnel to determine their safety. However, in coal mines, safety information and relevant production information such as methane, which is predominantly carbon monoxide, are concentrated in monitoring rooms to increase
