Temporal and Spatial Evolution Characteristics of Digital Geomorphology in Affected Zone of Underground Coal Mining Disturbance

This paper took southern No.3 area of Duerping Coal Mine in Taiyuan Xishan Mining Area as research area, and took 1:10 000 topographic map of pre-mining, post-mining and current mining three phases of study area as data source. ArcGIS was taken as experiment platform, and slope, aspect and topographic relief were taken as digital geomorphological evolution analysis factors for analyzing spatial and temporal evolution characteristics of digital geomorphology under the influence of underground coal mining disturbance in the study area. The results show that the slope and topographic factor can well reflect the digital geomorphic evolution of coal mining area caused by underground coal mining disturbance, and aspect can also reflect to some extent.
