Using five sub-meter high-resolution satellite images of WorldView, QuickBird and GeoEye from 2010 to 2014, taking the small landslide on the southern side of Dagushan iron mine dump in 2013 as an example, the parameters of landslide body area, slip distance, elevation variation before and after landslide and landslide volume were obtained. This method was then used to study the large-scale landslide occurred on the northern side of the dump in 2014. The results show that the landslide area on the southern side of the dump is about 15 000 m², the height difference is about 10 m, and the volume is about 61 000 m³, whereas the landslide area on the northern side is about 315 000 m² and the width is about 504 m. The landslide body slides about 295 m from south to north, with extension of about 208 m on both sides. The remote sensing evaluation result is consistent with the actual landslide situation, indicating that the high-resolution remote sensing technology can provide basic data for the monitoring and disaster assessment of landslide disasters in mine dumps.
