highlight=null, articleAbstract=In order to reveal the deposition law of pyrrhotite dust in human respiratory tract at construction site,and propose effective occupational disease protection measures,we took the pyrrhotite sample in the sampling roadway of a metal mine in Anhui as research object and establish a three-dimensional model of human respiratory tract.Then,under different concentrations of pyrrhotite dust and different work areas,we simulated the particle deposition in human respiratory tract during the transportation and shoveling processes.The results showed that the pyrrhotite under different respiration intensities,processes,and particle sizes is mainly deposited in the throat and trachea of the human body.When the particle size is greater than 5.456 μm,that is,the operator is close to the tuyere in the tunnel,all the mineral dust will be deposited in the respiratory tract of the human body.The total particle deposition rate of the respiratory tract will first decrease with the increase of particle concentration and then fluctuate steadily.And the total particle deposition rate will increase with the increase of particle size and respiratory intensity.The farther the distance from tuyere in the tunnel,the smaller the total particle deposition rate.Based on the deposition law of pyrrhotite dust on the respiratory tract of the human body and actual working conditions,corresponding protective measures are proposed., authors=LIAO Huimin, ZHU Yilong, SU Hong, LI Ming, authorsList=LIAO Huimin, ZHU Yilong, SU Hong, LI Ming,

articleAbstract=为揭示磁黄铁矿尘在施工现场人体呼吸道的沉积规律，以安徽某金属矿采样巷道磁黄铁矿矿样为研究对象，运用Fluent等软件，建立人体呼吸道三维模型，对不同作业区域运输和铲装2种不同工艺流程下、不同质量浓度的磁黄铁矿尘在人体呼吸道的颗粒沉积进行模拟。结果表明，不同呼吸强度、不同工艺、不同粒径下的磁黄铁矿主要沉积在人体的咽喉以及气管部分，当矿尘粒径大于5.456 μm时，即作业人员在巷道中距离风口较近的作业区域作业时，矿尘将全部沉积在人体呼吸道中。人体呼吸道的总颗粒沉积率随颗粒质量浓度的上升出现先下降而后波动稳定的规律，随颗粒粒径与呼吸强度的增加而增加，距运输巷道风口越远总沉积率越小。基于磁黄铁矿尘在人体呼吸道沉积规律及实际工况，提出了相应的防护措施。, authors=廖慧敏, 朱逸龙, 苏红, 李明, authorsList=廖慧敏, 朱逸龙, 苏红,
