摘　　要：通过深入分析深部岩体工程发生岩爆灾害的各种影响因素,利用事故树分析方法找出导致岩爆灾害的最小割集,并对其结构重要度进行分析。结果表明,岩爆灾害是基于高地应力完整硬脆岩体中发生的,岩爆灾害的发生受多因素影响,具有易发性。在目前岩爆机理的研究基础上,通过增强施工安全意识,对防治岩爆灾害的发生起主导作用。研究结果为进一步提高岩爆灾害防治与控制措施提供依据。Through deep analysis of kinds of affect factors on rock burst hazard happened on deep rock mass engineering, minimal cut set which caused rock burst hazard founded out by using fault tree a- nalysis method, and structure importance was analyzed. The result shows, rock burst hazard is base on high ground stress and in full hard and brittle rocks, happening of rock burst hazard affected by multifac- tor and had susceptibility. On the research basis of current mechanism of rockburst, through enhance construction safe sense plays a leading role on control of happening of rock burst hazard. Research result provides the basis for further improve the prevention and control measures of rock burst hazard.
