| Abstract: |
| In view of the unknown situation of the shape, location and distribution of the underground cavity, combined with the geological topography, electrical properties of rock strata and mining data, a comprehensive exploration technology is proposed. Firstly, the distribution of the mined out area group is detected by the transient electromagnetic method, and then the shape of the cavity is accurately detected by the three-dimensional laser scanning technology to provide data support for the safe mining. |
