Abstract: Excavation roadway of island workface is one of the difficulties in the field of rock burst prevention in deep mining. Rock-burst factors was analyzed to determine the risk degree of rock-burst of driving roadway, through the method of theoretical analysis, numerical simulation, field monitoring, by coupling analysis of lead abutment pressure, isolated coal pillar stress concentration, geological structural stress, based on the principle of stress control. And large cross section design scheme of the driving open-off cut roadway and comprehensive prevention and control technology were took. 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, which could provide a reference for the similar conditions of rock burst prevention.
