Introduction. Failure to comply with the requirements for the technological microclimate can lead to the development of occupational diseases and accidents. Therefore, in the general system of measures that ensure normal working conditions, one of the most important tasks is to reduce heat emissions.

Problem Statement. The paper studies the thermoradiation mode of workplaces. For this purpose, a scientific method based on the construction of radiation diagrams is used. The irradiation field of an object is based on the radiation diagrams of various sources that affect the working space.

Theoretical Part. Diagrams are used to express the quantitative parameters and boundaries of the distribution of radiant flows in the total field of irradiation of the workplace. Diagrams are built for different operating modes and operations based on theoretical calculations or real measurements. The method of diagrams is considered on the example of the cementation section of the foundry. The result of replanning, i.e. changing the location of the furnaces installed in the room, is shown.

Conclusion. The study of the intensity of thermal irradiation of the workplace by the method of diagrams showed that changing the layout of production equipment, as well as protection by distance, helps to reduce heat radiation and thus ensure compliance with sanitary and hygienic standards adopted for production facilities.

Introduction. The paper considers traffic in Kombaynostroiteley square in Rostov-on-Don. The necessity and possibility of organizational improvement of the situation on this road network section is noted. Taking into account the active development of the city in particular and the Rostov agglomeration in general, the results of the study will be relevant in the development of the control system and the street network.

Problem Statement. It is necessary to record and evaluate the main parameters of road and pedestrian traffic on the considered section of the road network in order to further improve the organization of traffic.

Theoretical Part. Conflict points and conflict situations on a given section of the road network are analyzed. For three days, traffic and pedestrians density during rush hours was recorded. The corresponding average-per-day indicator is calculated. Traffic flow composition from the point of view of types of transport is described. The data is visualized as charts and cartograms.

Conclusion. Traffic density and composition determines its speed, so they are taken into account in the design of traffic control systems, the development of the street network and the development of the general plan of the city. For the section under consideration, the rush hours are 10 a.m. and 5 p.m. The intensity increases up to 10 a.m., changes slightly from 11 a.m. to 7 p.m., and then decreases.

Introduction. Currently, there are increasing threats of wildfires that destroy landscapes, economic objects and human lives.

Problem Statement. The purpose of this study was to compare some innovative technologies for extinguishing wildfires and study the prospects for research in this direction.

Theoretical Part. Technologies for extinguishing wildfires are being developed in several empirical directions. We use aerosols of metal-containing compounds and dispersed liquids with gas, as well as unmanned remotely controlled aircraft for extinguishing forest fires. For crown forest fires, a fire barrier is used. To extinguish peat fires in hard-toreach places, a helicopter equipped with fire-fighting missiles is used. Peat fires are also extinguished by creating a vertical curtain using fast-hardening foam based on a solution of carbamide-formaldehyde resin. According to the concept of patentology, technology is considered as a set of functionally related technical objects and methods protected by patents, based on their innovative significance. System-forming elements in this case are concepts based on the characteristics of both technical objects and technologies, and patent objects.

Conclusion. It is advisable to build long-term plans for creating patent objects in the field of extinguishing natural fires. It is necessary to consider the scope of the patent results and outcomes of patentological analysis in accordance with the basic criteria of achieving a technical result of design technology, degree of innovation and empirical orientation.

Introduction. For a long time, the issues of improving the reliability of machines using the integral indicator have remained relevant. The operation of hydromechanical excavator elements is considered from the standpoint of structural safety.

Problem Statement. The paper shows the method and algorithm used to calculate the stretching of the excavator implement.

Theoretical Part. The study has identified the ways to improve reliability using the integral reliability indicator. The authors have obtained the equations: for the steel fatigue strength; for the stress concentration factor; for the effective stress in the dangerous section and the stretch life. The distribution of methods for managing the integral reliability indicator by the stages of the machine's life cycle is presented. It is noted that in order to obtain an optimal strategy for improving the excavator reliability, it is necessary to minimize the value of the integrated reliability indicator. The method of complex analysis of input factors is developed, and for serial and mass production — a general set of recommendations for increasing the component life. The distribution of disadvantages by structural, technological and operational factors for shafts, axles, gears, metal structures, chains, and special parts is obtained. The methodology for creating virtually trouble-free machines, including principles, a comprehensive program and a reliability management system, is described.

Conclusion. The use of the proposed system makes it possible to develop and manufacture high-reliability machines and to ensure a systematic reduction in the integral reliability indicator. The functioning of the machine reliability management system guarantees their creation with the same level of reliability, which will ensure the competitiveness of the equipment and the absence of consumer complaints.

Introduction: This article is devoted to improving the safety of elevators — the most popular hoisting-and-transport devices. The paper presents the results of an indirect assessment of load of load-bearing elements of elevators for residential buildings based on the results of regular monitoring by service organizations.

Problem Statement. Processing of the monitoring results was carried out on the basis of the idea of random nature of influencing factors and performance indicators. The data of observations of 15 elevator units of various load capacities installed in residential buildings with different number of storeys and passengers were processed.

Theoretical Part. The following indicators are accepted as the main ones, which characterize the load of the main elevator drive: machine time coefficient and specific number of starts per minute of pure machine time. For each of the indicators, distribution functions and probability densities are constructed.

Conclusion. Indicators of loading of the elevators vary within wide limits; no stable correlation between the indicators was established; each elevator is characterized by a pair of values of the machine time coefficient and the number of inclusions. The main purpose of the results is the possibility of using them to assess the adequacy of the formation of loading modes in the simulation of passenger elevators in comparison with real indicators.

Introduction. The article considers the dynamics of air pollution by stationary sources in the Russian Federation from 1998 to 2016. Harmful emissions into the atmosphere cause great harm to all living organisms. As a result, the life expectancy of the population is significantly reduced. Therefore, the assessment of pollution volumes and subsequent measures for the protection of atmospheric air are priority tasks of our time.

Problem statement. The objectives of the study are to analyze the dynamics of pollution, build a mathematical model of this process, and implement a forecast for a five-year period.

Theoretical part. Data for the work is taken from the official statistical book. Microsoft Excel and StatSoft Statistica computer technologies are used for calculations.

Conclusion. Based on the analysis, an adequate mathematical model is constructed, which may be of interest for predicting the anthropogenic impact on the environment.
