Abstract：Tunneling roadway of island working face is one of the difficulties in rock burst prevention in deep mining. Rock burst factors was analyzed to determine the risk degree of rock-burst of driving roadway, through theoretical analysis, numerical simulation and field monitoring, considering the coupling influence of advance abutment pressure, isolated coal pillar stress concentration and geological structural stress, based on the principle of stress control. And large cross section design scheme was applied for open-off cut roadway tunneling and comprehensive control technology was established. And the characteristics and causes of rock-burst events occurred in the period of excavation were analyzed, and achievements of rock burst prevention were summarized. The results show that the adopted technical scheme is effective, providing references for rock burst prevention in similar conditions.
