摘要：

The stemming length of blasting hole is an important blasting parameter that affects the blasting effect. Based on the practical engineering, the 3D FEM simulation models with different stemming lengths are built; and the fluid-solid coupling theory is introduced. After the ANSYS/LS-DANA simulation calculation and the comparison of the stress of the key parts, the classical blasting theory is verified; and the optimal stemming length is obtained. And it provides references and help to blasting numerical simulation.
