| 摘 要： | 用光散射数字尘计对施工隧道装运碴时颗粒物浓度进行了测定。纵向分布呈现掘进面至送风口浓度的曲线由高渐低，风管铺设段呈水平分布，提示风管铺设段隧道内污染物排出顺利。运碴车辆往返运动时，可消除或减少送风口远离掘进面通风阻碍污染物向外移动的不利影响，使掘进面污染物被带至风管铺设段，顺风流方向移向洞外。

| Abstract: | The concentration of the suspended particles at transporting dregs was determined with a light scat cring dust meter constructing tunnel.Dust concentration from driving aspect to blowing holeis from high to low and presents vertical distribution. Pellet in laying blowpipe section presents horizontal distribution. This prompts that pollutants in laying blow pipe section are easily discharged.When transporting dreg vehicle goes there and back,it will promote the pollutants in driving aspect moving to laying blowpipe section and going out of bole by wind. |
