摘要

The occupational hazards prevention and control in coal mine currently lacks of pre-evaluation on prevention and post-evaluation on control effects. The risk assessment model for the occupational hazards in coal mine is built up based on the hazard theory, then the risk evaluation on coal face No. 1 to 3 is performed respectively by means of fuzzy comprehensive evaluation method. The reliable evaluation results testify the rationality and practicability of the model. Implementing the research in this field is significant to enrich the theory and improve work quality of the occupational hazards prevention and control.
