The diffusion area simulation of gases released by coal fire
Abstract：Wuda coal fire area,where the coal fire is serious,was chosen as the study area,the diffusion of gases in atmosphere,such as CO,CO2,CH4 and SO2,were studied with the Gaussian plume Model on the ArcGIS platform.The study indicates that the gases diffuses along the downwind,and theirs concentrations takes on Gaussian distribution where is in the prevailing westerly winds Wuda,and the urban area of Wuda city is in a higher concentration and the gases have a severely impaction on the residents.
