Abstract: To determine rockburst influence factors and influence degree scientifically, and then study targeted stronger rock-burst prevention and control measures, use fault tree analysis method to analysis rock-burst influencing factors qualitatively, use Boolean algebra method to calculate the influence degree of various factors, and divide rock-burst influence factors into three grades, propose "weaken Coal and rock burst hazard; pre-assessment, comprehensive monitoring and dynamic control; strengthening management and mining optimization" three rock-burst control countermeasures. Practice proved that the effect is fine, the research has a strong theoretical and practical guiding significance to the prevention and control of rock-burst.

Key words: rock-burst, FTA, comprehensive monitoring, dynamic prevention and control
