摘　　要：为了确定多因素耦合对煤层自燃危险性影响作用的重要程度,建立了基于粗糙集理论的煤层自燃危险性综合评价模型和知识库,分析了煤层自燃灾害的特征,并应用粗糙集理论和信息熵理论对影响煤层自燃危险性的因素进行数据挖掘。通过对淮北某矿区多个煤层自燃危险性决策表约简表明,影响煤层自燃的核心因素有5个,其重要程度排序为漏风条件、变质程度、开采方式、地质构造、含硫量。In order to determine differentiation factors that influence coal seam spontaneous combustion risk, this paper establishes a comprehensive assessment model of coal seam spontane- ous combustion risk based on rough set theory and knowledge bases. The paper also applied rough set theory and information entropy to the characteristics of coal seam spontaneous combustion hazards, and investigated the influencing factors of coal seam spontaneous combustion risks. The analysis of decision tables indicated that there are 5 core factors that influence coal seam spontaneous combustion, its ranking, air leakage conditions, metamorphic degree of coal, exploitation method, geological structure and coal sulfur content.
