| 摘 要： | 矿山采场路面喷洒YCH抑尘剂后,逐日测定了路面粉尘含湿量、路面粉尘粒径分布、汽车行驶后瞬时扬尘浓度.路面喷洒抑尘剂10d后,瞬时扬尘浓度仅为4.9mg.m-3,降尘效率可达98.4%.与矿山路面每天喷洒4次水相比,路面喷洒YCH抑尘剂时节水率98%,降尘成本降低31%.

| Abstract: | After the road in the test mine was sprayed with dust suppressant,the instantaneous road dust raising concentration behind the running truck,the particle-size distribution,and water content of the road surface dust were measured every day.On the tenth day,the instantaneous road dust raising concentration was 4.9 mg/m3,and the dedusting efficiency was 98.4%.Compared with the measure of spraying water,the measure of spraying dust suppressant on the road not only saved 98% water but also reduced the 31% cost of dedusting. |
