Description	The paper deals with formulation of CFD simulation, which describes fluid flow in atmospheric boundary layer in coal stockpile surround. The paper presents preliminary phases of global project, which aim to spontaneous ignition of coal matter in coal stockpile and coal dump. First part of the global task is focused on generation of Earth's surface topology on the basis of GIS data. Second task is focused on simplification of simulation domain and reduction of mesh size by substitution of mine building by porous subdomain. Simulations of flow in boundary layer include only eight dominant directions of wind which are specified by means of wind rose. The FFT analysis is applied to wind direction, intensity and temperature too. Spectrum of velocity and temperature were used to transient CFD simulation with real time 1 month.
