Spontaneous combustion of coal pile often needs to have three main conditions: one is the tendency of spontaneous combustion of coal quality, two is good oxygen supply conditions, three is poor heat dissipation conditions. The spontaneous combustion capacity of various coals is different, and some are easy to spontaneous combustion, such as lignite, long flame coal, etc. Some are not easy to spontaneous combustion, such as lean coal, anthracite, etc., in addition, the higher the sulfur content and moisture content of coal, the faster the oxidation reaction rate, the more heat release, the more easily spontaneous combustion of coal. Coal pile heating is oxidation reaction, so the coal pile spontaneous combustion requires a certain porosity, good ventilation conditions. The oxidation reaction of the coal pile emits heat. If the heat dissipation condition is poor, the heat accumulation will improve the temperature of the coal pile. The higher the temperature of the coal, the more intense the oxidation reaction is. Therefore, the coal pile temperature measurement of different types of coal pile oxidation layer can be set up a reasonable anti-spontaneous combustion monitoring temperature, through the coal pile oxidation layer temperature measurement to predict whether spontaneous combustion will occur in the coal pile.
