为探讨地质勘探行业呼吸性粉尘浓度与总粉尘浓度的关系 ,为利用历史总粉尘测定资料进行呼吸性粉尘浓度的估算提供参考依据 ,本文用 3种采样器对地质勘探行业 9个省 (自治区 )地质勘查局地勘接尘作业的呼吸性粉尘浓度与总粉尘浓度进行了测定分析。结果表明 ,我国地质勘探行业接尘作业呼吸性粉尘浓度与总粉尘浓度的比值为 1∶4 6～ 4 8
In order to explore the relationship between the concentration of respirable dust and the concentration of total dust in geological prospecting industry, this paper provides a reference for estimating the concentration of respirable dust with the data of historical total dust. In this paper, Geological Exploration Bureau of dust exploration operations dust concentration of respiratory dust and total dust concentration were analyzed. The result shows that the ratio of respirable dust concentration to total dust concentration in dust collection operation in China’s geological exploration industry is 1: 46 ~ 48
