The invention discloses a deep-buried goaf boundary detection method and application thereof, and belongs to the technical field of railway engineering geological investigation, and the method comprises the steps: respectively obtaining mineral mining data and surface deformation feature data of a deep-buried goaf to be investigated, and judging the difference of the two data through the comparison of the two data, thereby achieving the detection of the boundary of the deep-buried goaf. And when the difference does not exceed a preset threshold value, a controllable source magnetotelluric method and a large-tonnage wide-line seismic wave reflection method are specifically adopted to carry out joint detection on boundary data, so that the boundary data of the deeply-buried goaf are accurately obtained. The method for detecting the boundary of the deep-buried goaf can effectively solve the technical bottleneck of exploration of the deep-buried goaf with the mining depth exceeding 1000 m, compared with a traditi
