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.

Verification of the Construction and Architectural Component of the Design of the Fire Protection Regulations

Sysoev

2022

A systematic study of compliance with the planning standards of the construction and architectural component of the design of fire protection regulation according to the basic indicators that ensure fire resistance and fire safety of the building has been carried out. Detailed audit was conducted to verify evacuation routes and passages at the facility to the fire protection regulations. A detailed audit on the verification of protective barriers against smoke to the fire protection regulations has been implemented. Verification studies are implemented on a specific object. The required degree of fire resistance of the objects of various functionality has been fixed. The survey of compliance of building structures, evacuation routes and passageways, smoke barriers with regulations and guarantees of fire protection have been presented. It is established that the required degree of fire resistance of a multifunctional shopping and office center depends on the height of the building and the maximum floor area of all its parts of various functional fire hazards. During the compliance check of the multifunctional shopping and office center, violations of the requirements of norms and rules on fire safety were revealed.

“…Analysis of the compliance of the architectural and construction part of the design with fire protection and the development of engineering and technical solutions to ensure safety at social facilities in the service sector, is regulated by normative documents [1][2][3][4][5][6][7][8][9][10][11]. It should be noted that during the inspection, inventory of objects of the social, technical sphere of vital activity, the strategic component during their implementation, regulatory documents are recorded, for example SNiPs, GOSTs, standards, and so on, regardless of the object profile [12,13,14,15].…”

Engineering and Technical Solutions for Ensuring Security at Social Facilities

Zaitsev

2022

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.
