Abstract: Combined with coal seam occurrence and mining technical conditions in Shendong Mining Area, influence factors of carbon monoxide emission are analyzed and the prevention and control technology is proposed to solve the carbon monoxide emission at the working face. The results show that, multiple methods, such as the residual coal control at working faces, the reasonable air distribution, and the prevention of coal seam spontaneous combustion, they are used to control carbon monoxide emission, which ensures the safe production at working faces.
