Numerical Simulation Research on Single Hole_unilateral Protecting Borehole Wall Blasting

Abstract:

3-D Numerical simulation on the directional pressure relief partition side of blast hole isolation material though LS-DYNA software. The result shows: the semicircle isolation material can put off the time that the explosion stress wave arrived at the hole-wall and reduce the peak of stress wave. Meanwhile, it proves that the explosion in the material substance is more powerful than that in the air. So it has certain directive significance on rock blasting on the slope.
