在内因火灾的早期阶段,发现和控制煤炭自燃源是煤矿防灭火最紧迫的问题之一。最完善的方法是检测矿井大气中火灾生成气体的含量。这类方法在火区温度很高时是有效的。近来,矿山救护研究院东方分院采用了正在发展中的控制内因火灾火源的方法,此法的原理是测定底板表层气体组分的异常。但是,由于煤中涌出气体的成分与
In the early stage of internal fires, discovering and controlling coal spontaneous combustion sources is one of the most pressing issues in coal mine fire prevention and fighting. The most complete method is to detect the content of the fire generated gas in the mine atmosphere. Such methods are effective when the fire zone temperature is high. Recently, the Eastern Branch of the Mine Ambulance Research Institute has adopted a method of controlling the fire source of internal sources of fire. The principle of this method is to determine the abnormality of the gas composition of the surface of the soleplate. However, due to the composition of the gas gushing out of the coal
