Purpose. Establishing regularities of change in the injury probability and development of a methodology for determining the injury probability of coal mine workers to improve the occupational health and safety (OSH) management system efficiency. Methods. Methods of mathematical statistics and mathematical analysis were used in the data processing of coal mine workers’ injuries; probability theory and risk theory were applied for setting equations to determine the injury probability; correlation and regression analysis were used to determine the density and nature of the dependences reflecting changes in the injury probability. Findings. A calculator has been developed to compute the injury probability of an employee. This instrument distributes the probability into three “zones”: high probability – “red zone”, medium probability – “yellow zone”, and low probability – “green zone”. The injury probability for all employees of the mine administration was calculated. It was found that the clo-sest relationship between the number of injuries and the calculated probability is observed for mining sites (medium probability) and for tunneling sites (high probability). For employees with a calculated high injury probability, in most cases, the causes of injury were objective and less dependent on employees themselves. For employees with a medium probability, the causes independent of and dependent on employees were approximately equally correlated. In the case of employees with a low probability, the main reasons were subjective – dependent on the employees themselves. For employees in the main operational sites (mining and tunneling), the cause of injury is directly related to the specifics of the production operations performed: the presence of loose space. Originality. For the first time, relationships were determined between the injury probability and the profession. We also established relationships between experience at the enterprise, age, marital status of an employee and the injury causes, as well as between the actual number of injuries and the calculated injury probability. Practical implications. A method for determining the injury probability of coal mine workers has been developed and implemented. The ways of improving the methods for calculating the injury probability are determined.

In terms of occupational safety and health (OSH) management system functioning at the enterprises of the Coal Business Unit of DTEK ENERGO LLC, a number of procedures and techniques have been developed and implemented for improving the OSH management system. However, rate of injuries and accidents is still fairly high at these enterprises. It is proposed to describe effectiveness of the OSH management system as a catastrophe of the “assembly” type. It is further proposed to describe effectiveness of the OSH functioning in mine by a potential function. To this end, probability of an accident (injury) is considered as a coordinate of the disaster, level of development of the coal mining technology means an external parameter, and the internal parameter is presented by the level of readiness of miners to perform processes and operations. With increase of internal control parameter characterizing level of the miners’ readiness to perform basic and auxiliary processes and operations, probability of accident and injury generally decreases; however, this curve is bifurcated by its nature. With increase of external control parameter – i.e. level of technology development - the curve narrows, while width of the catastrophe band decreases. At sufficiently high level of technology development, the system exists only in one state of equilibrium; but when passing a certain critical value, splitting and two alternative stable states appear. The area of the curve, which is limited by critical values of the level of miners’ readiness to perform technological processes and operations, determines an undesirable effect or a value reciprocal to the OSH effectiveness in the mine. At insufficiently high level of technology, a catastrophe (high probability of an accident) can happen both at insignificant and sufficiently high level of the miners’ readiness. In practice, in each mine, these parameters should be normalized and set according to the results of expert evaluation; and quantitative indicators of the level of miner’s readiness to perform processes and operations can be obtained during the psychophysical testing.
