Introduction. Industrial accidents are associated with various factors: human, social and economic problems, which we must strive to eliminate, thereby ensuring a safe working environment. Statistics on occupational injuries are necessary to assess the degree of hazard and potential risks associated with occupational factors to protect workers. Labor inspectorate statistics play an important role in developing national policies, systems, programs and strategies to improve safety and working conditions for miners in Zimbabwe. Labor Inspection in Zimbabwe is one of the main safety control mechanisms. Labor inspection statistics enable the government to monitor the mining industry and better analyze mining safety compliance issues.

Problem Statement. The article discusses the prediction of accidents in the mining industry of the Republic of Zimbabwe in order to reduce the incidence of injuries. Economic and social development in the mining industry requires reliable analysis of injury statistics. Statistics of injuries in various production processes are given.

Theoretical Part. In the process of data analysis, interpolation algorithms are used embedded in mathematical software. Statistical reports on occupational injuries provided by the Federal State Statistics Service were used as basic information.

Conclusion. Mathematical forecasting of industrial injuries in the mining industry in Zimbabwe allows us to determine the likely values of the predicted indicators.

Introduction. The article analyzes the most likely damage from fatal industrial accidents. The analysis revealed the main cause of industrial accidents — violation of safety requirements during the organization of various works and their implementation in practice. A special role in the prevention of accidents is played by the process of employee training, which requires careful preparation. That is why, in order to minimize accidents and erroneous actions of personnel, it is proposed to introduce a new business game "Guardians of labor" into the practice of training.

Problem Statement. The objectives of this research: creating a business game for learning and adapting security requirements at the enterprise; developing and comparing different options for evaluating security solutions; developing information analysis skills; developing the activity of game participants.

Theoretical Part. Training in the form of a business game gives you the opportunity to work out the skills of analyzing information, evaluating and comparing different approaches to solving a problem. The authors of this study created a business game "Guardians of labor". It helps you to strengthen knowledge of occupational safety and health, fire safety, first aid and accident investigation.

Conclusion. The proposed method helps improving the professional qualities of students, develops the ability to reasonably defend their opinions and analyze alternative approaches.

Introduction. The paper considers one of the ways to improve performance characteristics of products based on polymer composites with epoxy matrix by improving their thermal stability and durability by introducing modifiers.

Problem Statement. The objective of this study is to compare the heat resistance indicators of epoxy matrices of classical design with compositions improved by modification with carbon nanostructures.

Theoretical Part. For basic information, the selection of modifying materials, the selection of the optimal composition of the binder based on epoxy resin, low-molecular hardener, plasticizer and filler was carried out. The technology of introducing modifiers into the structure of the epoxy matrix was developed. Thermogravimetric and differential thermal studies were used to analyze changes in the temperature of the beginning and the end of the thermal effect, the temperature of the maximum thermal effect, the amplitude value and width of the peak effect, the index of its shape, and the mass loss of heated samples depending on their formulation.

Conclusion. The results of the study indicate the possibility of using epoxy resins filled with powdered carbon nanostructures in various areas of production due to the positive effect of additives on thermal stability indicators.

Introduction. The cargo frame is a load-bearing element of the car, since the body and chassis are installed on it. Therefore, high strength requirements are imposed on this node. For safe and reliable operation of the truck, the frame must be adjusted and balanced, since even minor changes in the geometry can negatively affect the overall condition and safe operation of the equipment. This article discusses methods for lengthening the load-bearing elements of trucks on the example of a light-duty car "GAZelle".

Problem Statement. Car frame extension is a high-tech process that requires high precision, knowledge, and the use of a wide range of equipment. The extended frame adds a number of advantages to the car, which in turn makes it possible to transport cargo with larger dimensions. The main goal of this work is to enable the car to transport bulky cargo. Also, in the process of extending the frame, it is checked for cracks, breaks and corrosion foci and, if necessary, repairs are made, which increases the reliability, safety and service life of the entire structure as a whole.

Theoretical Part. When extending the standard support, all attachments are removed from the car: fuel tanks, body, transmission, drive shaft. All that remains is the cab, the bridge, and the engine. Then the frame is cut in three places.

Two cuts are made at a distance of 80 cm in the direction from the cab to the rear bridge, and the last one is made at a distance of 40 cm from the rear bridge in the direction of the rear overhang. Then a longer channel is installed on the frame. It is secured with rivets, bolts, or lap welding. After that, the structure is assembled back. This takes into account the redistribution of loads and the need for high-quality performance of all types of work.

Conclusion. The frame is an integral part of not only trucks, but also an important component of passenger cars, as well as light-duty vehicles. Its technical condition is just as important as the condition of, for example, the braking system, as it also ensures the safety of both the driver and pedestrians. The lengthening of the frame in the conditions of repair and mechanical enterprises allows you to increase the load capacity of serial cars of the GAZelle series while ensuring their reliability and safety.
