“…The selection of this peak is determined by the design requirements. At the same time, use the HITRAN2016 (High resolution transmission molecular absorption database) data tool [6][7] , input the key parameters of infrared wave band and gas type, and obtain the cross of characteristic absorption peaks of the two gases through analysis, as shown in Figure 2 and Figure 3. It can be seen from Figure 2 that CH 4 gas crosses with C 2 H 4 gas in the characteristic band of 3.33um, and does not cross with C 2 H 2 .…”

With the progress of science and technology and the vigorous promotion of the coal mine industry, more and more gas sensing devices are used in coal mines. However, due to the special environmental conditions such as high temperature, high humidity, high dust, and many kinds of toxic and harmful gases in coal mines, gas sensing devices are generally affected by cross interference. This paper combines the current actual application of gas sensing devices in coal mines, starting with the measurement objects, use forms, and number of measurement parameters, The method of combining theory with experimental verification is adopted to study and put forward the measurement principle, cross interference influence mechanism, cross interference blacklist, cross interference inspection method and qualification determination method of gas sensing equipment with three advanced sensing principles of infrared, laser and electrochemistry in coal mine environment. The results show that the cross interference influence of gas sensing equipment is widespread, and different working principles have different cross interference effects, If necessary, carry out cross interference test verification. Finally, in combination with the underground application of coal mine, it is recommended to attach great importance to the impact of cross interference on coal mine safety production, and strictly follow the requirements of anti cross interference.
