煤炭自燃是一个极其复杂的物理、化学过程。虽然限于当前的技术条件,对煤炭自然发火的有关参数还不可能进行完全的定量分析,对发火的位置及波及的范围还不可能准确地确定,对发火的时间还不可能进行严格的控制,但是对产生自然发火的基本因素,在定性分析上却有了比较明确的认识。这就是必须有可燃的物质,有漏风供氧的条 Spontaneous combustion of coal is an extremely complicated physical and chemical process. Although limited to the current technical conditions, it is impossible to conduct a full quantitative analysis of the relevant parameters of spontaneous combustion of coal, and it is impossible to accurately determine the location and range of ignition and the impossibility of strictly controlling the time of ignition. However, there is a clear understanding of the basic factors that cause spontaneous combustion in qualitative analysis. This is the need to have a flammable material, air leakage of oxygen
