Abstract:
The open-pit mining activity has caused the surface to be in an unstable state of change, causing problems such as slope instability, geological hazard, and damage to the ecological environment. The analysis of open-pit mine surface changes is of positive significance to the sustainable development of the mining area and the improvement of the ecological environment. Based on the spatial-temporal process, the open-pit surface changes area can be divided into three dynamic surface units due to the open-pit mining activities, that is, the progressing mining area, the continuing mining area and the discontinued mining area. Taking the East open-pit mine of Pingshuo Mining Area in China as an example, this paper uses the multi-sequential Digital Elevation Models (DEMS) for calculation to extract the dynamic surface units. The geometric changes and vertical changes of the open-pit surface were analyzed and evaluated quantitatively. The analysis method of surface changes due to open-pit mi
ning activities quantitatively in the GIS environment, is of practical value for the investigation and evaluation of artificial surface changes in open-pit mines.
