Abstract：According to the problem of the strength and frequency of rock burst increased obviously,along with the increasement of mining depth and mining range in China,the paper summarized and analyzed the conditions of rock burst occured,the results showed that only meeting three conditions which included internal condition,structure condition,stress condition,the rock burst might arise.According to the conditions and characteristics of rock burst happened in recent years,rock burst mines were divided into five categories which included shallow rock burst mine,deep rock burst mine,structure rock burst mine,hard roof rock burst mine,coal pillar rock burst mine.On the ba-sis of analysis about force source which initiated rock burst in different coal mines,which included the prevention measures aimed at shal-low rock burst mine were mining by sequential and roof pressure control;the prevention measures aimed at deep rock burst mine were pro-tection layer mining,mining by sequential and mining intensity control;the prevention measures aimed at structure rock burst mine were drillhole pressure relief;the prevention measures aimed at hard roof rock burst mine were the length of unsupported roof control;the pre-vention measures aimed at coal pillar rock burst mine were pressure relief.
