At present, in Russia, as in many countries, the issues of reducing industrial injuries, as well as increasing the effectiveness of measures taken by employers in the field of industrial safety and introducing a culture of safe work, are widely discussed. The relevance of the topic is due to the fact that Russia is a participant in the Vision Zero campaign, founded by the International Social Security Association (ISSA) and the Institution of Occupational Safety and Health (IOSH). The article discusses the history of the emergence and development of the Vision Zero strategy from the corporate to the international level, provides the goals and objectives of the concept of “zero injuries”, studies the indicators of its implementation, and analyzes injuries at coal enterprises of the Russian Federation. As a result, a methodology for solving the tasks in the form of a list of necessary measures and target indicators of their achievement was proposed based on the example of one of the largest coal companies—JSC “SUEK-Kuzbass”. Based on the results of studies, the main conclusion has been formulated—the “Vision Zero” concept is an effective tool to promote an effective occupational safety management system.

The results of the analysis of statistical data on accidents at Russian mines caused by explosions in the workings space have shown that explosions of methane-dust-air mixtures at underground coal mines are the most severe accidents in terms of consequences. A detailed analysis of literature sources showed that in the total number of explosions prevails total share of hybrid mixtures, i.e. with the simultaneous participation of gas (methane) and coal dust, as well as explosions with the possible or partial involvement of coal dust. The main causes contributing to the occurrence and development of dust-air mixture explosions, including irregular monitoring of by mine engineers and technicians of the schedule of dust explosion protective measures; unreliable assessment of the dust situation, etc., are given.  The main problem in this case was the difficulty of determining the location and volume of dust deposition zones in not extinguished and difficult to access for instrumental control workings. Determination of the class-shape of coal dust particles is a necessary condition for constructing a model of the dust situation reflecting the aerosol distribution in the workings space. The morphological composition of coal mine dust fractions with dispersion less than 0.1 has been studied. Particle studies conducted using an LEICA DM 4000 optical microscope and IMAGE SCOPE M software made it possible to establish the different class-shapes of dust particles found in operating mines. It was found that the coal dust particles presented in the samples correspond to the parallelepiped shape to the greatest extent. The mathematical model based on the specialized ANSYS FLUENT complex, in which this class-form is incorporated, is used for predicting the distribution of explosive and combustible coal dust in the workings space. The use of the obtained model in production conditions will allow to determine the possible places of dust deposition and to develop measures to prevent the transition of coal dust from the aerogel state to the aerosol state and thereby prevent the formation of an explosive dust-air mixture.
