Collapse goaf in old coal mine seriously threatens the production and safety of large scale mine , detecting the collapse goaf has become an important research topic in current 3D earthquake. Geological model is established according to the actual occurrence of the goaf , using ray tracing theory carries out numerical simulation. Systematically analyzes the morphological characteristics of collapse goaf and analyzes the spectrum characteristics of reflected wave on the time section. Combines with some typical engineering examples , sums up the seismic response characteristics and seismic attributes characteristics of the collapse goaf in the seismic data , it provides a guiding significance for coal mine safety production.
