Over the past 10 years, the mining industry of Russia has seen a greater than three-fold decrease in injury rates, thanks to the successful implementation of innovative labor safety technologies. Despite this, injury levels remain unacceptably high compared to the leading mining countries, which results in increased mining costs. For the mining areas of the Arctic Zone—unlike other regions located in areas with a more favorable climate—the injury rates are influenced not only by the underground labor conditions, but also by the adverse environmental factors. For the Russian Arctic zone, the overall injury risk is proposed to be calculated as the combined impact of occupational and background risk. In this article, we have performed correlation analysis of the overall injury risks in regions of the Arctic zone and regions with favorable climate conditions. Using the Kirov branch of “Apatit”, Joint-stock company (JSC) as an example, we have calculated the risks related specifically to occupational injury rates. We have constructed the relative injury risks and their changes over time and have developed a “basic injury rate matrix” that makes it possible to visualize the results of the comparative analysis of the injury rates on the company’s production sites and to determine priority avenues for improving the occupational safety and lowering the injury rates.

Analysis of the risk structure of injuries and occupational diseases in the mining industry of the Far North of the Russian Federation

Purpose. To reduce the risks of accidents and injuries on the basis of vocational selection of the stuff for work in the mining industry, as well as training and maintaining their skills of safe work. Methodology. To solve the problems considered in the article, the following were used: analysis of information from scientific and technical sources on the influence of psychophysiological factors on occupational injuries; correlation-regression analysis of statistical data on occupational injuries; experimental research on efficiency of miners work in laboratory and mine conditions at various physical activities. Findings. The article substantiates the role and necessity of conducting professional psychophysiological selection procedures for mining workers, monitoring their functional state. The methodology of professional psychophysiological selection procedures, innovative training and behavioral audit is proposed in order to increase the injury protection of workers. Innovative ways of training and maintaining the safe working skills of miners are explored. The role of modern gadgets with installed applications for assessing the severity of physical work in terms of heart rate is investigated. Originality. The novelty of this study is to substantiate a comprehensive approach to the preventive precautions against occupational injuries in the mining industry at the stages of personnel selection, training and further control of the consequences of production activities. Practical value. Principles are developed for selecting, training, and maintaining skills for the safe work of personnel for the mining industry.

Based on the analysis of the mining and geological conditions for developing coal deposits in Vietnam, the existing mining safety regulations, the application of methods for calculating the air supply of working and development faces using the methane factor and modem methods of mathematical modeling of the ventilation of mines threr was developed the procedure for analyzing the efficiency of air distribution management considering the proposed indicator - energy efficiency coefficient for ventilation systems, determined by the efficiency of air use and energy consumption. Relations have been obtained that determine the relationship between the aerodynamic resistance of negative regulators, the number of simultaneously developed working and development faces, the performance of main ventilation fans and the consumed electric power.
