一、前言高倍数泡沫已于10年前用于井下灭火,根据我们对高倍数泡沫的研究经验认为:体积庞大的泡沫对于粉尘是具有很好粘着性的。基于泡沫有控制粉尘的能力,我们在几个煤矿的机采工作面进行了试验。虽然,在这以前一些工厂在泡沫降尘方面已发表过文章。但是其中大部分所采用的办法都是把大气中的粉尘吸入盛有泡沫的容器中,粉尘与泡沫相接触后而被粘着。这种 I. INTRODUCTION High-fold foam was used for underground fire extinguishing 10 years ago. According to our research on high-fold foams, bulky foam has good adhesion to dust. Based on the ability of the foam to control the dust, we conducted tests at machine mines at several coal mines. Although, in the past some factories have been published articles on the foam dust. However, most of them adopted the method of sucking the dust in the atmosphere into the foamy container, and the dust was adhered to the foam. This
