| Abstract: | The advance blasting stress relieving method is the effective control method to strong rock burst and extremely strong rock burst. But its drilling blasting is still in the stage of empirical design. The paper researches the mechanism of the advance blasting stress relieving method by using the discrete element method to provide guide for the design of the drilling blasting and takes the successful application in construction of JinPing auxiliary tunnel west section as an example to verify the reasonable of... |
