Abstract: The landfills of waste rock formed in the mining and metallurgical industry are sources of powerful harmful dust impact on the atmospheric air, which negatively affects the safety of the surrounding territories and the population living there. When predicting the mutual placement of several landfills, it is advisable to carry out an assessment of the aerodynamic structure of the wind flow, which is formed when it flows around them. The work uses the method of discrete vortices for numerical modeling of the process of the flow around the landfills, which realistically reflects the process of unsteady flow. The method of numerical calculation of the vortex wake structure, which is formed during the flow around the landfills, has been developed. On the basis of the methodology, the software implementation was carried out. Computational experiments were carried out for different variants of the geometric parameters of the landfills and different distances between them. The change in the structure of the vortex wake over time and its geometric dimensions was studied. The results of the study can be used in the design of landfills and assessment of the impact of dust generation zones on the environment.
