Abstract: 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 analysis 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 multifactor 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.

Key words: Rock burst hazard, Fault tree analysis, Rock mass engineering, Precautionary measures
