【 摘 要 】

Through the occupational hazard control effect of Nan yu mine in Taiyuan, the investigation, inspection and examination methods of occupational health scene were confirmed for qualitative and quantitative evaluation. The total layout of the mine, personal protective facilities, emergency rescue, health auxiliary room, occupational health management are in line with national standards, the existing occupational risk factors in the production process to determine are dust, free silica, noise, hand-vibration, carbon monoxide, carbon dioxide, nitrogen dioxide, sulfur dioxide, ammonia, hydrogen sulfide, manganese and its compounds, microclimate, power frequency electric field, but parts of the dust and noise concentration (or intensity) have exceeded. The mine occupational hazards control measures are feasible and effective, but some post still need to strengthen governance.
