自古已来人们普遍认为:兵来将挡,火来水防。所以许多人多会采用煤堆喷水的方法来防止自燃。其实,喷水并不能完全解决自燃问题,而只起到防尘作用。因为大量的水喷在煤堆上,水流穿过煤堆,使之在煤隙中流窜,造成更多更大的空隙。此孔隙可以使大量的氧气和空气进乳煤中,加剧化学反应,从而只能起到助长自燃,而不是制止自燃现象。防止煤堆自燃一般可采取化学方法和机械方法。
It has generally come to people since ancient times that soldiers will block and fire will come to prevent water pollution. Therefore, many people will use coal-jet method to prevent spontaneous combustion. In fact, water spray and can not completely solve the problem of spontaneous combustion, but only play a role in dust control. Because a large amount of water is sprayed on the pile of coal, the water flows through the pile of coal so that it flows through the coal seam, resulting in more and larger gaps. This pore can make a lot of oxygen and air into the milk coal, aggravating the chemical reaction, which can only play a role in contributing to spontaneous combustion, rather than to stop the phenomenon of spontaneous combustion. Prevent coal spontaneous combustion can generally take chemical and mechanical methods.
