摘　　要：煤层自燃是煤与空气中氧气相互作用的结果,自燃倾向性的煤层被开采、破碎后在常温下与空气接触,发生氧化,产生热量,使其温度升高,出现发火和易燃的现象。所以应及时准确地进行火灾早期预报,防止煤层积热自燃。Coal combustion air oxygen coal and is the ~sult of the interaction of the self - ignition orientation of coal, mining, breakage is in contact with air under normal temperature, oxidation, generate beat, make its temperature, appeared angry and flammable phenomenon. Timely aml accurately tore cast, preventing fire early on coal combustion heat product.
