Abstract: Coal spontaneous combustion in longwall gobs is a major disaster in coal mines. In comparison to other disasters, this phenomenon has a strong concealment. To explore the influencing factors of coal spontaneous combustion in longwall gobs and the related interactive mechanisms, 15 factors from 4 aspects are identified on the basis of relevant literature. The logical relations among the factors are quantified by inviting experts to evaluate. Afterward, by combining decision-making trial and evaluation laboratory (DEMATEL) and interpretive structural modeling (ISM), the influencing degree, influenced degree, centrality, and causality of factors are calculated. A four-level hierarchical structure model is also established. Research shows that combining DEMATEL and ISM can discover the key factors that influence coal spontaneous combustion in longwall gobs and intensely explore the interactions and relationships among these factors. Research results can provide the basis for preventing and controlling coal spontaneous combustion disaster in longwall gobs.
