In order to control the rock burst, based on the distribution of bearing pressure, the borehole deformation and blasting vibration are used in order to shift the peak bearing pressure to the deep rock mass, and to release some concentrated stress, therefore to increase the carrying capacity of decompression zone. Construction parameters controlling rock burst and the prevention measures for the drilling tool from jamming are obtained by using the field burst tests on tunnel, ingate, and shaft excavation. Test results show that it could successfully control the rock burst at the front end, when the ratio of crossing over cycle to excavation depth reaches at 2~3. And a triangular arrangement of super-deep hole is able to resoundingly control the rock burst in tunnel, ingate and shaft excavation face. In addition, the interval of 1.5~2.5m layout plus the deep vibration hole of 2.0 ~3.0m is able to successfully control the rock burst in the tunnel waist wall or in the wall of a shaft well. And then smooth blasting or bench smooth blasting with temporary rock bolting is able to avoid roof fall or wall caving in the ingate., authors=LI Junping¹, WANG Shi², LIU Caiwang², HU Ming³, WANG Yongyan², authorsList=LI Junping;WANG Shi;LIU Caiwang;HU Ming;WANG Yongyan, authorCompany=1.
