description The invention belongs to the technical field of rock mechanics, and particularly discloses a quantitative determination method and system for a rock blasting damage area range. The method comprises the following steps: firstly, carrying out flat ray wave velocity field inversion on a sound wave travel time matrix between m transmitting-receiving pairs before and after blasting to obtain an initial wave velocity field matrix, and calculating to obtain an initial slowness matrix S1; a ray path matrix L and a ray travel time matrix t among the m transmitting-receiving pairs are updated and iterated by adopting an MSFM ray tracing method and an SIRT iterative algorithm; whether an arrival time difference matrix delta T between the real sound wave travel time matrix T and the ray path matrix t meets the iterative convergence requirement or not is judged, wave velocity fields before and after blasting meeting the requirement are output, a wave velocity change field delta V is worked out according to the wave veloci
