【 摘 要 】

Fault rockburst has great harm and fault activation is the direct cause of its occurrence. On the basis of reviewing a large amount of literature, the examples of the fault rockburst in some coal mines in China, the distribution characteristics of in-situ stress in the vicinity of fault and various criteria and assessment methods of fault activation were systematically summarized and analyzed. The influencing factors of the fault rockburst disaster are expounded in terms of the features of fault, mining depth and layout of working face. The corresponding prevention and control measures were put forward based on the understanding of the mechanism of the fault rockburst, and it is believed that the early monitoring, warning and control of fault activation should be strengthened. Finally, the reasons why it is difficult to predict the fault rockburst accurately were discussed, and the problems existing in the current research and the directions for future research were pointed out.
