Numerical Simulation of the Effects of Driving Blasting Vibration on the Surrounding Rock in Deep Mine Tunnel

Using ANSYS to establish the model of driving blasting in tunnel, the deformation of rock caused by gravity is calculated according to the model, and regarding calculated nodal displacements as the initial conditions to add to DYNA display dynamic analysis, effective stress results of analysis unit peak show that the numerical simulation can reveal the rules for the rock blasting stress distribution,which can providing a basic theory to choose supporting form and supporting practice.
