Abstract: In order to ensure the health of the occupational health practitioners in mining enterpris⁃ es，the occupational health field survey method，occupational health detection method and occupational health checklist analysis method were used to investigate and evaluate the current situation of occupational disease hazards in an underground iron mine in Anhui Province. The results showed that the management system of occupational health in the iron mine was complete，and the main occupational hazard factors were dust and noise. The qualification rates of dust and noise were 100% and 76.7% respectively，and the maximum noise intensity was 101.0 dB（A）. In the occupational health examination in 2021，one person has occupational contraindication of noise，one person has occupational contraindication of dust，and there is no suspected occupational disease. The occupational disease prevention work of this underground iron mine basically conforms to the requirements of relevant national laws and regulations，but due to the limita⁃ tions of industrial processes and equipment，it is impossible to effectively control the noise hazard from the source. The company should strengthen the intelligence and automation of process equipment and second⁃ ary prevention of occupational health，continue to improve the occupational health management system， and ensure the occupational health of operators.
