Return air corner carbon monoxide concentration determination method, device, medium and equipment

The invention relates to the field of coal mine production safety, in particular to a return air corner carbon monoxide concentration determination method and device, a medium and equipment. The method comprises the steps that coal body parameters and mine parameters of broken coal bodies in a preset area of a current coal seam are obtained, and the preset area comprises a goaf and an area between a rear scraper conveyor and a support rear stand column; the carbon monoxide generation rate of a laboratory coal sample at the preset temperature is obtained, and the laboratory coal sample is a processed crushed coal body from a preset area; according to the coal body parameters, the mine parameters and the carbon monoxide generation rate, the carbon monoxide generation amount corresponding to the multiple preset sources in unit time is determined; and determining the carbon monoxide concentration in the air return corner area according to the carbon monoxide generation amounts corresponding to the multiple preset
