The loss quantity of high grade coal due to the coal's spontaneous combustion has been to 4.2 billion tons. Besides, the loss quantity has been growing by 2000-3000 million tons every year. Moreover, the heavy casualties caused by the fire hazard annually lead to heavy toll of lives and nearly billions yuan economic losses. Not only does the coal's spontaneous combustion wastes coal resources, but also leads to the serious environmental and ecological problems. The massive poisonous gas which is caused by the coal's fire will seriously pollute the atmospheric environment and directly endanger our living space.According to the characters and rules of spontaneous combustion for the...
