通过分析煤的氧化放热性、储热性和自燃供氧条件3个关键因素与地温的关系，推导出煤温与排氧速度、放热强度的关系式，以及热风压和升温条件的两个计算公式。同时在自燃实验台上进行了实验研究。研究结果表明，地温提高了煤的氧化放热能力，改善了煤自燃的储热供氧条件。
By means of analyzing relationship between ground temperature and three key factors that oxidizing and heat releasing property of coal, heat storing and oxygen supplying condition of spontaneous combustion, some results, include a relation formula between coal temperature and velocity of exhausting oxygen, intensity of releasing heat and two formulas about thermal air pressure and prerequisite for temperature raising, were deduced. Meanwhile, experiment was done on spontaneous combustion experimental platform. The investigation results show that oxidizing and heat releasing capacity of coal is strengthened and heat storing and oxygen supplying condition of spontaneous combustion are improved because of ground temperature.
