Improving the procedure for group expert assessment in the analysis of professional risks in fuel and energy companies
The lack of a unified approach to the assessment of professional risks in fuel and energy companies (FEC) in the national regulatory environment and a high degree of subjectivity of the results of hazard identification and risk assessment makes mathematically sound recruitment of an expert group urgent and necessary. The article presents the results of a comprehensive study on hazard identification and risk assessment at 6,105 workplaces in 24 branches of a FEC company based on the application of the expert assessment method and a scientifically sound qualitative and quantitative selection of experts. The priority vectors of factors are determined, global priorities are calculated, the size of the expert group (15 persons) is determined and mathematically substantiated for carrying out hazard identification and risk assessment at workplaces with sufficient reliability of results. For the first time, a set of factors characterizing the FEC companies that influence the determination of professional competence of experts is proposed. The formed expert group presented more precise, objective and consistent results of risk assessment. Standards for free distribution of personal protective equipment (PPE) and wash-off agents to 7,234 company employees for implementation and trial use were developed. A fragment of the results obtained for a driller's workplace is presented. This approach allows a significant increase in objectivity and efficiency of the professional risk management system and provision of the PPE to employees in the concept of a risk-oriented approach helping to prevent industrial injuries and improve the level of occupational safety culture in fuel and energy companies taking into account global practice.

Modern mining of mineral resources to be the industry accepted by the society must meet the criteria for sustainable development. Work safety is its important element, which is a particular sphere in underground coal mines in the view of natural hazards occurring numerously, including the catastrophic failures. Among them are gas hazard, fires and rock burst hazard. The selected methodological solutions in terms of their recognition and technologies applicable for the actively combat of these threats, which are featured by high efficiency, have been pointed out.
