今年5月内蒙古兴安岭阿尔山林区发生森林大火,引起国内外注目。 关于这场大火的起因,我注意到4个极其重要的线索,这就是:①火区地面是熔岩区(即玄武岩熔岩,为火山岩),火苗均沿岩石裂缝冒出,当明火扑灭了,经风一吹,灰烬中又萌发明火,火苗又冒出。看来裂缝下有“可燃性气体”涌出,致使这一过程反复了3次;②有“过路火”,即路这边的火苗会突然穿过路面蔓延到路那边,这显然由于路那边也有可燃性气体;③这种火苗可直窜,犹如打开的打火机火苗。据森林卫士讲,这种火苗可上窜20多米。这种火苗同样表明了在其下部有可燃性气体的“冲出”;④森林大火不是呈面状,而是呈线状分布,据我推测,这是一条大的断裂构造带,沿这条断裂带,均有可燃性气体的“泄漏”与“涌出”。因此,所谓“森林大火”,实际是天然气燃烧,这无疑给这场大火的扑灭工作带来了极大的困难。
In May this year, Inner Mongolia Xinganling Aershan forest fire broke out, attracting attention at home and abroad. As for the cause of the fire, I noticed four extremely important clues: ① The ground of the fire area is a lava area (ie basaltic lava and volcanic rock), and the flames emerge along the rock cracks. When the open flame is extinguished, Wind blows, the ashes again in the open flame, the flame again. It appears that cracks under the “flammable gas” gushing, resulting in the process repeated three times; ② “crossing the fire” that the road side of the flames will suddenly spread across the road to the side of the road, which apparently due to the road Flammable gas over there; ③ This fire can be channeling, like a lighter flame opened. According to forest guards say, this flame can channeling more than 20 meters. This flames also showed a “punch-out” of flammable gas in the lower part of it. ④ The forest fire was not linear but rather linear, and as far as I suppose it was a large fault zone, Fault zone, both flammable gas “leak” and “gush”. Therefore, the so-called “forest fire” actually burns natural gas. This undoubtedly posed tremendous difficulties for the extermination of the fire.
