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.

“…The number of risk factors depends heavily upon enterprise's management team competence, its ability to form adequately strategic goals and manage their achievement as well as upon skills to develop and implement innovative projects, manage both human and financial resources, and capabilities to run effective operational management of productive processes (Volkov & Horoshkova, 2018;Domínguez, Martínez, Piñón Peña, & Rodríguez Ochoa, 2019). Risk level can also be decreased significantly through skillful and economical use of material resources, equipment, and capital stock of the enterprise (Domingues, Baptista, & Diogo, 2017).…”

Purpose. The main purpose is to identify underground coal mining risks as well as approaches for their reasonable and efficient management taking into consideration internal production reserves in order to improve technological processes' efficiency and operational efficiency. Methods.In order to achieve a target goal, the paper highlights and analyzes production processes involving the highest risk level. Methods of analogous risk characteristics, systematic approach towards developing a system of coal mining risk management as well as methods of distributed control have been applied to develop risk management innovative methods.Findings. The reasons stipulating coal mining risks based upon geologic, technologic, and economic aspects of mining practice as well as imperfection of human psychology, have been defined. Attention is drawn to the necessity to involve efficient counterweights relying upon additional bonuses for detecting violations, innovative trainings, and training of personnel to prevent safety inhibitions. A matrix structure has been demonstrated as the optimum structure for risk management, which should implement the idea of distributed control. Combination of effective operative information support with a system of open communication helps to develop conditions to change attitude of participants of underground coal mining towards risks to ensure safety. Originality.For the first time, the reasonability of combining matrix structure with distributed risk management has been demonstrated as well as substitution of unifactor discrete cumulative characteristic of explosion probability or methane ignition for analogous characteristic, dependent on several factors. Practical implications.Performance assessment throughout coal mines' operations improves reliability and safety of production processes and mining practices as well as provides for proactive risk management.

“…The results showed that there were low accident frequency rates and overall security improvements after the technology development in the 1980s and beyond. Dominguez et al (2019), in their study, aimed to draw attention to the relationship between the working conditions of underground mining and occupational accidents worldwide, in the State of Mexico and the State of Guanajuato. In order to improve working conditions, they applied the decision matrix risk-assessment (DMRA) technique, which is classified according to the severity and likelihood of accidents in order to assess risks and to identify activities that should continue.…”

Developments of countries are interpreted through many parameters. One of the most important parameters according to the order of importance is perhaps the occupational accidents. Especially in recent years, work related (or occupational) accidents occurred at different sectors did not decrease; they even increased despite the developments in the technology and emphasis made on the regulations. This situation can be interpreted as an open debate in which the employees still do not internalize the work they do. Often, enterprises do not choose the right personnel for the job or the personnel chosen are not oriented to the work with the through proper methods. When the mining sector is taken into account, this problem becomes even clearer. Among the many reasons for this problem, it can firstly be mentioned about the difficulty of employing qualified and well-educated personnel. Since the enterprises do not have many options in the solution of this problem, their approach to work accidents should be institutionally a highest priority. During this process they must also use proactive approaches. For example, all accidents and occupational diseases should be recorded, possible causes of them should be put forth, and statistical analysis should be conducted to guide the future of the institution. In this study, the work accidents took place in both underground and surface facilities at Western Lignite Corporation (WLC) which is one of the most important lignite producers in Turkey between the years 2014 and 2018 were analyzed by Data Envelopment Analysis (DEA). The types of accidents were also examined and interpreted using the information obtained from the calculation of accident frequency, accident weight and accident probability rates. With the sensitivity analysis realized, it was tried to draw attention to the occupational safety measures to be made in the future.
