Abstract: As result of the work, simulation of optoelectronic sensor (OES) of optical radiation of flame and smoldering was performed. OES is part of a multi-criteria optoelectronic control device for emergency and pre-emergency situations in coal mines. Analytical dependencies were formulated for the computer simulation of EOS was developed. A check of the adequacy of the computer simulation was performed. Simulation of the radiation flux arriving at the entrance pupil of the EOS during the smoldering of coal dust and the flame burning of methane-air mixture was carried out taking into account the influence of the intermediate medium. The spectral ranges from 2.45 to 3.2 μm and from 4.3 to 4.6 μm are used to control the radiation of the flame. The spectral range from 3.5 to 4.2 μm is used to control the of smoldering radiation. The elemental base for the EOS has been selected taking into account the data on the spectral transmittance of the intermediate medium.
