Numerical Simulation of the Tunnel Blasting Process in Weak Intercalated Layer

Abstract:

In order to study the effect which weak intercalated layer produces in the rock during the process when explosives transferring the energy, this research uses ANSYS/LS-DYNA toexplore the numerical simulation of the law which the stress wave of weak intercalated layer rock with different thickness propagates and decays. It also compares the effect to stress wave in certain position when the thickness of the intercalated layer is different or inexistent. The outbreak pheno-menon of the rock with weak intercalated layer occurs in the blasting process is analyzed as well, so the effect of weak intercalated layer should be fully considered when arranging blast hole around the tunnel. Then the research provides the theoretical basis for selecting blasting parameters.
