摘　　要：通过研究掘进工作面产尘机理及粉尘产生过程,比较泡沫降尘技术较其他常规降尘手段所具有的优势,设计了泡沫降尘的工艺流程以及系统的安装工艺。泡沫降尘技术在新安煤矿掘进工作面的现场应用测试数据显示,泡沫对全尘的降尘效率达到84.43%,对呼吸性粉尘的降尘效率为68.85%,分别是水雾除尘的2.11倍和1.72倍,降尘效果显著。The technological process of froth dedust and the installation technology of the dedust system were designed by studying the dust generation mechanism and process in the heading face and comparing the forth dedust technology with other conventional dust suppression technologies.The measured data obtained in the application of the forth dedust technology in the heading face of Xin'an Coal Mine indicated that when forth dedust technology was applied,the total-dust removal efficiency reached 84.43% and the respirable dust removal efficiency reached 68.85%,2.11 and 1.72 times of the dust suppression technology by water spray respectively,so remarked dust removal effect can ensure miners' health and work safety of the mine.
