摘　　要：为提高清水喷雾降尘效率及润湿剂的使用效率,基于对润湿剂降尘机理的分析,对初选的4种润湿剂单体进行了表面张力实验,及单体与复配溶液煤尘沉降实验,综合考虑多方面因素,确定了高效环保的煤尘用喷雾润湿剂的配方;同时,结合田陈煤矿综掘工作面实际情况,设计研发了润湿剂分散自动添加装置,在7110综掘面应用后,与原有的清水喷雾相比,全尘平均降尘率提高了33%左右,呼尘平均降尘率提高了28%左右,喷雾降尘效率得到有效改善。To improve the efficiency of spray and dust reduction and efficiency of the use of the wetting agent,based on the analysis of mechanism of wetting agent dust,four kinds of wetting agent monomer were chosed to make the surface tension of the experiment,and the sedimentation experiment of dust for the monomer and the mixed. Considering various factors,determined the effective environmental protection of coal dust by spray wetting agent formula. Combining the actual situation of fully mechanized workface in Tianchen coal mine,designed and developed the dispersed automatic controlled apparatus for wetting agent. After application in 7110 fully mechanized workface,the dust-laying rate of total coal dust increased by 33% on average,the rate of respirable dust increased by 28% on average,compared with the original water spray. The spray dust efficiency can be greatly improved.
