Occupational hazards analysis and control on underground construction of hydropower engineering

Underground construction activities of hydropower engineering are characterized by long period, complicated work and involvement of a big variety of professionals; compounded by the poor underground working conditions, it is of great significance to improve the occupational health protection. By probing into the specific construction activities, machinery and equipment and make-up of the involving professionals, and in the light of the charac- teristics of each construction stage, this article makes an analysis of the types and features of occupational hazards resulting from different stages of construction activities. Based on the analysis, this article proposes preventive and controlling measures accordingly so as to prevent and control the hazards for the professionals concerned.
