Abstract By analyzing the mechanism of rock burst start-up，the blasting effect of the concentrated stress distribution in the roadway is studied by numerical simulation methods；and the dredging method of pressure with deep-hole interval blasting based on theory of rock burst start-up is proposed. The research results show that：(1) The interval of deep-hole blasting in roadway should be the area of rock burst start-up，otherwise it will play a negative role. (2) It is limited to dredge and debase concentrated stress by increasing intension of roadway support. (3) On one hand，the dredging method of pressure with deep-hole interval blasting can dredge and debase the degree of concentrated stress or energy of the area of rock burst start-up，thus the rock burst start-up step can be prevented. On other hand，it let the area of rock burst start-up firstly move to the deep coal wall；and the total energy which is consumed by rock burst start-up in dredging pressure area increases，but the energy release speed reduces. The good effect of application the research results to field engineering is got.

Key words： mining engineering interval blasting dredging method of pressure concentrated stress theory of rock burst start-up rock burst roadway
