Rockslide is one of the main geological disasters in China.Each rockslide disaster has different characteristics,so its emergency and rescue plans are not identical. The digital elevation model before and after rockslide and the aerial image with 0.35 m resolution were used as the data source. The digital landslide technologies were also adopted to quantitatively interpret such information of the Jiweishan rockslide as scale,topographical change,direction of movement,disaster features and affected limits. The Jiweishan rockslide is a typical multiple huge disaster that experienced a chain reaction consisting of "creep sliding along week layer-burnish surrounding rock-fragment flow-barrier lake". According to the disaster characteristics,the best location of engineering work for buried miners underground was explored by combining the collected layout of the Gonghe iron ore deposit with the results of the remote sensing interpretation for the Jiweishan rockslide. The results obtained by the authors could provide valuable references for the study of rockslide disaster characteristics and emergency rescue engineering using remote sensing technology in the future.
