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.
