Coal spontaneous combustion of coalfield outcrop made coalfield outcrop subsided. In order to reasonably manage the coalfield outcrop fire zone,the important parameters affecting coalfield outcrop fire area were studied and the macroscopic numerical modeling was made for dif-ferent buried depth of coal seam,porosity and permeability by Fluent simulation software. The variation law of velocity field and temperature field of porous medium of coalfield outcrop was ob-tained,and the treatment scheme was put forward according to the effect of the porosity and per-meability on the temperature distribution in the fire area.
