The article is devoted to solving the topical problem of creating a system for occupational risk management in mining enterprises that would be able to function under the conditions of a limitation in the organization's economic and information resources.The study aims to develop an approach of occupational risk management at a mining enterprise based on an improved and fundamentally new matrix method of assessing occupational risks, which allows increasing the efficiency of managerial decision-making.The suggested method is based on a set of methodological approaches aimed at minimizing the drawbacks inherent to standard risk assessment matrices that were identified and studied by the authors in the process of system analysis.In particular, the regression analysis of the experts' evaluations has provided the basis for calculation models of occupational risk assessment, which allow increasing the level of detail in evaluation results.Alongside that, the fact that the suggested method uses intuitively comprehensible continuous variables of probability/damage, on the one hand, reduces the uncertainty in expert assessment, and on the other hand, preserves the visibility and convenience of using the classical matrix method for occupational risk assessment.To optimize the use of the assessment groups' resources, the authors have developed an algorithm for an occupational risk management procedure based on a comprehensive qualitative study of scenarios of the negative impact of hazards on mining enterprise workers.The paper provides recommendations for systematization and inventory of occupational risk analysis results to determine and plan protective measures.We have described the results of the testing of the proposed methodreceived in the course of analysis of the miners' working conditions in the operating coal mines -which indicate an increase in the level of detail of the output data and the possibility of applying a unified approach to the analysis of heterogeneous occupational risks.In addition to that, the paper shows the positive effect achieved by the use of the suggested method compared to the standard matrix assessment of occupational risks.
