矿井沼气燃烧与沼气爆炸都是沼气和空气混合物遇火后发生的放热反应,但由于二者对矿井生产及矿工生命安全影响情况不同,人们对它们往往产生悬殊的认识。安全生产的实践告诉我们,大多数沼气爆炸事故都是由沼气燃烧开始,进而发展成沼气爆炸事故的。欲杜绝矿井重大灾害事故,就应在严 Mine biogas combustion and biogas explosion are both exothermic reactions of biogas and air mixture in case of fire, but due to their different impacts on mine production and miners’ life safety, people often have a great deal of understanding about them. The practice of safe production tells us that most of the methane explosion accidents started with the combustion of biogas and then developed into a methane explosion. In order to put an end to major mine disaster, it should be strict
