Study on Numerical Simulation of Loose Blasting Stress Field of the Rock Blast Hole Affected by In-Situ Stress
Abstract:Choosing appropriate parameters and model, the simulation study in loose blasting stress field of the rock blast hole affected by in-situ stress was made using ANSYS/LS-DYNA numerical analysis software. The results show that the explosion distribution around the hole, rock displacement and the bursting of the particle rock will be changed by the influence of in-situ stress, the strength of the stress field is restricted, the movement speed of the particle decays faster, and the development length of crack decreases.
