| Abstract: Objective To identify the occupational hazards existing in a underground mine enterprise and their critical control points, to research on occupational disease hazard prevention and control countermeasures. Methods In 2022, the current situation of occupational disease hazards was investigated by an on-site occupational health survey and occupational disease hazard detection methods for a underground mine enterprise in Heilongjiang Province. Results The mine enterprise exist coal dust, silica dust, noise and other occupational hazards, of which 1 coal dust concentration exceeds the standard, 2 silica dust concentration exceeds the standard, 2 noise intensity exceeds the standard. The dust excess rate was 18.75%, and the noise exceeded rate was 11.76%, other test results are in line with the occupational exposure limits. The enterprise occupational disease prevention facilities, personal protective equipment, and occupational health management conform the requirements, and occupational health surveillance needs to be strengthened. Conclusion The mine should enhance the maintenance of protective facilities such as dust prevention, vibration and noise reduction, formulate a reasonable labor and rest system, improve the occupational health surveillance items, regularly carry out occupational health education, training and publicity, to further protect the occupational health of workers. |
