Paper Title:
Simulation of Charge Structure Effect to Integrated Rock Blasting
  Abstract

Different charge structure has an important influence on explosive energy efficiency and rock blasting effect. On the basis of Misses strength theory, using ANSYS/LS-DYNA to simulate the integrated rock blasting effects under different charge structure conditions, including continuous coupling charge, continuous decoupling charge and interval charge. And the effective stress-time curves of typical elements are compared to analysis. The results show that air as a decoupling medium plays a good buffer function, which is an ideal charge form. And interval charge has a better effect to buffer the pore wall peak pressure, thus reducing the destruction around the blast holes.
