一、前言 作对对巷道火灾的灭火方法之一的泡沫灭火法,很早人们就进行了研究。但是,这些研究的中心主要是围绕发泡技术和泡沫在巷道里的输送技术,而有关灭火效果的实验研究却进行得很少。大型巷道里的火灾灭火实验,笔者有过实例,但这也仅仅是让20m长的坑木带燃烧,对于炽烈的火灾,要评价泡沫的灭火效果,可以说还不能得出定论。鉴于此,作者通过煤炭技术研究所等单位协助,曾在400m的试验坑道里,设置60m的坑木带并让其燃烧,借助高膨胀泡沫进行了灭火实验,本文就此实验的概况作一介绍。 I. Foreword As one of the methods of extinguishing fire in a roadway, the Foam Extinguishing Act was studied very early. However, the focus of these researches is mainly on the foam technology and foam transport technology in the roadway. However, experimental research on the effect of fire extinguishing has been carried out very little. Large tunnel fire extinguishing experiments, I have had examples, but this is only to make pit 20m long burning, for blazing fire, to evaluate the effect of foam fire extinguishing can be said that still can not draw conclusions. In view of this, the author through the Coal Technology Research Institute and other units to assist, had in the 400m test tunnel, set 60m pit belt and let it burn, with high expansion foam fire experiments, this article an overview of this experiment to make an introduction.
