煤炭自然发火是一个极其复杂的物理和化学变化过程。目前,尽管我们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,对发火的位置及其波及的范围还不可能准确地确定,但对形成自然必须具备的4个基本要素却有了明确的认识。这就是:有易燃的物质——浮煤;有漏风供氧的条件;有积聚氧化热的储热环境;有足够氧化储热的时间。根据我矿现场实践,我们认为最主要的
Spontaneous combustion of coal is an extremely complex physical and chemical change process. At present, though it is impossible to conduct a full quantitative analysis of the relevant parameters of spontaneous combustion of coal, it is impossible to accurately determine the location of fiery firing and the extent of its spread. However, there are four basic elements that must be posed Clear understanding. This is: there is a flammable material - floating coal; air leakage of oxygen conditions; accumulation of heat of thermal storage environment; have enough time to oxidize the heat. According to my mine site practice, we think the most important
