Paper Title:
Numerical Simulation Analysis on Explosion Stress Field of Different Charge Construction
  Abstract

There are different blasting stress field which around the blast hole caused by different charge when explosives exploded in the rock. Simulation analysis on borehole wall pressure and explosion stress field of rock at different charging structure was done by ANSYS/LS-DYNA. The simulation results indicate: stress of coupling charge is the maximum, water-decouple charge is the latter and air-decouple charge is the minimum; and whether air-decouple or water-decouple charge, peak stress value of model decreased along with the increasing of decouple coefficient, but the air-decouple charge show more obvious. Therefore, water-decouple blasting has good energy utilization.
