摘要
综述了煤层自然发火危险性评价指标的最新研究成果。煤炭的自然发火不但取决于煤的内在因素，还取决于促进煤自燃的外在因素。煤层自然发火危险性评价指标的系统分类方法应以煤炭对自燃的敏感程度和外在的开采条件为基础，并就自然发火危险性评价指标方法的某些局限性进行了评价。
This paper reviews the current achievements of rese arch on risk assessment index of coal spontaneous combustion.It has become a com mon view that the spontaneous combustion depends upon not only intrisic factors but also external factors.The classification risk assessment index of coal spont aneous combustion is based on the considerations of the degree of intrinsic comb ination and external mining factors.Every current method has its limitation in t he process of risk assessment of coal spontaneous combustion.
