ABSTRACT
The article discusses the issues related to the formation of an environmentally safe habitat in Underground Facilities (UF) where people stay for a long time. It is proposed to take into account the aerodynamic regime in the area of the facility and the level of air pollution when designing underground structures. It is shown that for the quantitative assessment of the air parameters of underground structures, it is advisable to use mathematical modeling based on well-known software tools such as ANSYS, STAR-CCM+ or specially developed programs. The proposed approach is illustrated by the example of designing natural ventilation for an underground facility where people are located. A method of integrated analysis of the choice of design solutions is proposed, based on mathematical modeling of the aerodynamic mode of the built-up area, taking into account air pollution from low sources of emissions within the built-up area and choosing the method of air exchange for the underground facility.
