摘　　要：为研究表面活性剂沉降机理,减小煤矿喷雾降尘水的表面张力,增强水与煤尘的结合能力,采用对比分析的方法,通过沉降实验研究了5种表面活性剂在不同浓度及复配条件下、添加增效剂Na2Si O3条件下对煤尘的湿润能力。In order to study settlement mechanism of surfactants, reduce the surface tension of the water for spray and aspirating in coal mine, enhance the capacity of the combination of water and coal dust,adopts the method of comparative analysis, five kinds of surfactants are studied by using sedimentation experiment under the condition of different concentration and distribution, add synergistic agent under the condition of sodium silicate wetting ability of coal dust.
