摘　　要：为了解释煤矿井下在进行瓦斯测定时,光波干涉瓦检仪和热催化瓦检仪检测结果不同,使得工程技术人员对井下瓦斯浓度不能准确把握,从而产生安全隐患。通过在新柳煤矿井下测点分别使用光干涉瓦检仪和热催化瓦检仪对瓦斯含量进行测定,并采集对应测点气体对其进行色谱成分分析,从而确定两种仪器的误差。再根据分析不同气体对光波的折射率,找出光干涉瓦检仪的误差产生原因并提出相应修正方法,最终得出影响新柳煤矿瓦斯检测结果不准的原因并提出相应措施。When detecting the gas in mine, there is difference between the result of optical interference gas detector and that of thermo catalysis gas detector. Technicians can not get the exact gas density, which may cause potential safety hazard. Through detecting content of gas by optical interference gas detector and thermo catalysis gas detector respectively in Xinliu mine, and analysing the collected gas by colour spectrum, the error can be decided. Then, according to the refractive index of different gases to light wave, the reason for the error of optical interference gas detector is found. Finally, the reason for the inaccuracy of gas detection in Xinliu mine is found and some countermeasures are put forward.
