In this paper, incising blasting engineering in granite row stone exploitation as the research object, in order to analyze the fracturing mechanism principles of V-shaped notch blasting and the influence of blasting parameter changing to V-shaped notch blasting effect, the elastic-plastic isotropy and multi-notched hole of plane strain model is set up. Dynamical finite element analysis software ANSYS/LS-DYNA is applied to calculate dynamic stress distribution and its change rule of rock around notched holes and between two holes, and dynamic fracturing mechanism is analyzed with fracture mechanics theory.
