Abstract: In order to prevent rock burst occurrence and control overlying irregular coal pillar of island working face, the relavant research progress of rock burst caused in China was reviewed.Taking Y484 working face of Tangshan Mine as the research object, the main controlling factors of rock burst in the overlying irregular island working face, which were mainly characterized by irregular coal pillar, large buried depth, local coal pillar and coal rock stratum structure, were analyzed.A method of preventing rock burst by making a weak structure was developed.The characteristics of the weak structure and the principle of preventing rock burst by adjusting stress distribution were described.A numerical model was established employing FLAC3D to analyze the deformation and failure process and stress distribution law of the working face of the overlying irregular coal pillar island and the weak structure was simulated by elastic-plastic constitutive model to verify the prevention and control effect of the weak structure on rock burst.Finally, through the field application, the technology of rock burst control based on weak structure was established and implemented.The stress and drilling cuttings methods were used to verify that the weak structure has a positive impact on the rock burst control under the given condition.
