摘　　要：通过系统安全工程的事故树分析方法,找出了影响采空区安全的主要因素,建立了采空区塌陷事故树图,求出了其最小割集、最小径集和各基本事件的结构重要度,并从这3方面全面分析阐述了各基本事件对引起事故发生的影响程度以及它们之间的逻辑关系。针对采空区塌陷事故发生的主要原因提出了所需采取的最简单有效的预防措施,为矿山安全管理提供了可靠的参考依据。By using the fault tree analysis of systematic safety engineering, the main factors influencing the safety of mined-out area were found and the fault tree chart of mined-out area collapse was established. The structural importance of its least cut set, minimum path set and various basic events were worked out, from which the effect degree of each basic event on the occurrence of the fault and the logical relation between them were analyzed. The simplest effective preventative measures that should be taken were proposed in view of the main causes for the mined-out area collapse fault, providing reliable reference to the management of mine safety.
