Based on the characteristics of high stress and high ground temperature in the deep coal mine, the evolution and breaking rules of deep mining-induced fractures, the spontaneous combustion mechanism of residual coal in goaf, and the related research results of numerical simulation of coal spontaneous combustion are analyzed, and the further research direction of multi-field coupling of coal spontaneous combustion in goaf of deep well is discussed, which provides theoretical research reference for the improvement of coal spontaneous combustion mechanism theory.%基于深井煤矿开采高应力、高地温的特点, 分析了深部采动裂隙演化及破断规律, 采空区遗煤自燃机理, 煤自燃数值模拟研究的相关成果, 探讨了深井采空区煤自燃多场耦合作用的进一步研究方向, 为煤自燃机理理论的完善提供了理论研究参考.
