| Abstract: |
| In July 2019, a goaf collapse accident?occurred in Luanping Huabing iron mine, the“Space-Sky- Ground- Depth” Multiply Exploration Technology Integrated System including remote sensing monitoring, transient electromagnetic detection, fretting exploration, TRT advance forecast, engineering geological drilling, and 3D laser scanning were used to detect the goaf accurately. Combining key techniques and methods of multi-scale monitoring, the model was built, confirming the location, shape, volume, and other 3D spatial data of the goaf, which provided a good foundation for stowing governance. This comprehensive survey method pioneered the integration of a variety of technical means, has the advantages of high efficiency, accurate data, and intuitive results, and has great promotional value for the survey of blind goaf areas. |
