摘　　要：对某地下卸矿站的湿润剂喷雾防尘技术与系统设计进行了研究。通过对矿尘的化学成分、粒径分布分析,以及用毛细管正向渗透试验研究了几种常见湿润剂湿润性能,从而确定湿润剂的配方。试验结果表明,湿润性能和矿尘的粒径分布、湿润剂类型、湿润剂质量分数和试验时间有关。以地下卸矿站为研究对象,根据卸矿站的作业特点与粉尘的产生特点,运用喷雾防尘的方法有效地抑制粉尘的产生,使卸矿站的环境得以明显的改善。其防尘效率受到供水水压、喷嘴类型等影响。The technology and system design of wetting agent spraying for dust control for an underground ore unloading station were studied. The chemical composition and size distribution of mine dust were investigated, and the wetting ability of several wetting agents was studied by the down-ward capillary seep experiment for determining the wetting agent composition. The experimental results show that the wetting agent performance was affected by dust size distribution and the type and mass fraction of wetting agents as well as the test time. According to the features of the operation and the dust forming in the underground unloading station, an effective spraying system for dust control was used to depress the dust, evi- dently improving the environment of the ore unloading station. The dust control efficiency was influenced by water supply pressure and nozzle type.
