Study on Numerical Simulation of Bench Blasting and its Elevation Amplification Effect

Abstract:

In order to research on the elevation amplification effect of blasting vibrational velocity of bench Blasting, Using FEM program of LS-DYNA, based on the simplified blasthole theory, established the single blasthole 140mm finite element model , draw elevation amplification is not unlimited magnified, but first increasing with elevation to certain extreme value , and then reducing along with the elevation .
