Abstract: To explore the application of occupational health risk assessment model in occupational hazards assessment in coal mines, the 12 main processes of 5 main sections in a large coal mine were selected as research object. Risk in the processes was assessed by the Romanian risk assessment model (Romanian model) and the International Council for Mining and Metals Risk Assessment Model (ICMM) and the similarities and differences between the assessment results by the two models were compared. The results showed that for the assessment of occupational hazards of the three occupational hazards, such as noise, CO and other toxic gases and welding fumes, the risk assessed by ICMM matrix method is medium level, assessed by quantitative method is unacceptable risk level, and assessed by the Romanian model is a 4-level medium. For the hazard of dust causing pneumoconiosis, the risk assessed by ICMM matrix method is high-risk level,by quantitative method is unacceptable risk level, and by the Romanian model is a 5-level high-risk level. In a comprehensive comparison, the assessment results of the Romanian model provide a better guidance for the risk classification and prevention of occupational diseases in coal mining enterprises.
