Abstract: In order to reduce the accidents in the heading face of coal tunnels, the study based on the visual management theory and accident cause "2-4" model finds that the visual communication could cut the relation between the direct reasons and accident causation chain to achieve the purpose of preventing the accidents. Taking the coal tunnels as the object, we carry out field research and collect the data about equipment, personnel allocation, illegal behaviors and latent dangers and design 6 kinds of safety signs for the tunnels. The signs could prevent the accidents which may occur in the tunnels and maximize the effect on protecting people's life safety.
