The invention relates to a geological radar chromatographic detection method for a disaster source in a mine recovery area, belonging to the technical field of geophysical exploration. The method comprises the steps of determining positions of transmitting points and receiving points; conducting geological radar chromatographic detection on a selected detection profile; conducting mesh generation on the profile; constructing an inversion equation set of wave velocity chromatography; determining the wave velocity distribution of the detection profile; and drawing a contour map of detection profile wave velocity distribution and recognizing the spatial position and the characteristic attribute of the disaster source. The geological radar chromatographic detection method for the disaster source in the mine recovery area realizes the quick, accurate, nondestructive detection on disaster source information in modernized mine recovery areas and plays a role in guiding underground safe mining.
