关于煤的自燃问题,其主要原因是由于吸收了空气中的氧气,使煤的组成物质氧化产生热量;再被水湿润,就放出更多的湿润热,会加速煤的自燃;煤的自燃也与煤本身的性质有关;还与煤层埋藏深度、煤层厚度、开采方法、通风方式有关等。煤的自燃从本质上来说是煤的氧化过程,对煤的自然分析预测采取综合防治,促进煤矿安全生产。 As for the spontaneous combustion of coal, the main reason is that due to the absorption of oxygen in the air, the composition of the coal is oxidized to generate heat. When it is wetted by water, more humid heat is released, which accelerates spontaneous combustion of coal. Spontaneous combustion of coal also And the nature of the coal itself; but also with the depth of the coal seam, seam thickness, mining methods, ventilation and so on. Spontaneous combustion of coal is essentially the oxidation process of coal, natural analysis and forecasting of coal to take comprehensive prevention and control, and promote coal mine safety in production.
