According to the huge losses of people's life and property caused by coal rockburst, we make numberical simulational research on coal deep buried roadway fault rock burst which is based on the related fators about the occurrence of fault rockburst. Simulation results show that,the stress in fault is the most significant,and with its continuously accumulation ,if it is up to the ultimate strength of coal and rock mass,which will occurre rib spalling, and even it will bring the accumulated elastic energy out ,then induced by fault rockburst. So simulation results are of guiding significance to the occurrence mechanism and predict of coal roadway fault rockburst.
