“…From the results of the study shown in figure 7, a further increase in the concentration of these surfactant solutions does not lead to a significant decrease in surface tension. The described phenomenon means: at the indicated TEAS concentrations, the adsorption layers of molecules are almost completely saturated with this surfactant at the liquid-gas interface [28,29]. Processing of bulk materials with surfactant solutions can be carried out both by irrigation of a source of dust formation, or bulk materials, and by processing with an air flow generated by special equipment.…”

The negative impact of the open method development of mining and processing enterprises of the Kursk magnetic anomaly on the environment is considered. The volume of unorganized emissions of dust and harmful gases into the atmosphere during blasting operations at the Lebedinsky GOK quarry is calculated. When processing the results of the experiment, the article used the “STATISTIKA” software package. Calculations of concentrations of harmful substances at the time of blasting showed that the concentration of carbon monoxide, nitrogen oxides and dust in the atmosphere of the quarry exceed the maximum permissible concentrations. Industrial general technical preventive measures aimed at reducing the emission of dust particles during serial explosions of iron-containing rocks at the facility are recommended. An engineering and technical solution has been developed to reduce dust and gas emissions during mass explosions at the quarry of a mining and processing plant. The method of controlling the wetting and sticking of dust particles is applied. Aqueous solutions with an anion active substance based on triethanolamine salts are recommended. The concentration of the surfactant is selected according to the value of the surface tension of the solution.

Engineering and technical solutions to ensure fire safety of the building and protection of people by deterministic factors have been installed. The object of research is a building of public social purpose. Constructive and planning solutions for preventing the spread of fire in the building of an object of class K0 for fire danger are diagnosed. The enclosing structures of the room must have a fire resistance index of at least REI 150. Technical solutions for evacuation routes and passageways, equipment that guarantees reliable protection from fires, communication in the building, ensuring procedures that implement the effective functioning of the fire Department to eliminate the source of fire have been formulated. Technical solutions for fire protection and communication systems of the building are justified in detail. Compensating measures are recommended for public buildings with an excess of the standard height and in the presence of six underground floors. It is specifically recommended to increase the fire resistance limits of load-bearing structures, stiffness cores – stair and elevator nodes and fire barriers to R/REI 180 and to provide the building with a type 5 warning system.
