The article discusses the problem of monitoring landslide processes in urban landfills of municipal waste, the consequences of which can be salvo emissions of toxic substances into the atmosphere, pollution of water bodies and the occurrence of biological and social emergencies. The results of studies of the territory of the existing waste landfill using aerial photography materials, photogrammetric image processing, construction of a digital terrain model and visual representation of dangerous areas where the body of a landslide is formed are presented.

Flash point and ignition are among the main indicators of the fire hazard of substances, as they characterize the fire and explosion hazard of vapor-air mixtures above the surface of liquids. The paper experimentally investigated the change in the flash point and ignition of flammable liquids (diesel fuel and industrial oil) with the addition of inert additives − perlite, activated carbon, silica gel, oilcorb and vermiculite. Oil-sorb and vermiculite showed the greatest efficiency. When adding the oil filler to diesel fuel, the flash point in the open crucible increased by 7.8 ° C and approached the ignition temperature.

The article considers the problem of atmospheric pollution forecasting spread taking into account the surrounding landscape and development based on mesh models of computational fluid dynamics. A functional model for solving this problem is presented. The feasibility of automating the stages of the investigated area geometric model and the computational mesh constructing, determining the initial conditions, as well as processing the obtained results to reduce the labor intensity of their implementation is justified. Usage example of software developed in the framework of the study, to which this article is devoted, for an automated solution to the problem of atmospheric pollution spread forecasting is given. A comparative analysis of automated operations using the presented software and without it was carried out.
