煤火已成为一个世界性的问题,结合前人研究成果及野外煤火实地观察,将煤火燃烧阶段分为氧化自热期、煤层燃烧期、熄灭期3个阶段,从产物特征、地质特征、生物特征及地球物理特征等方面分析煤火各阶段所具有的特征,为识别煤火燃烧阶段提供依据。
Coal fire has become a worldwide problem. According to the research results of predecessors and field observation of field coal fire, the combustion stage of coal fire is divided into three stages, ie oxidation autothermal period, coal burning period and extinguishing period. From the characteristics of products and geology , Biological characteristics and geophysical characteristics of the various phases of coal-fired fire have the characteristics of the identification of coal-fired combustion phase to provide the basis.
