Abstract

Open-pit mine landslides are dynamic disasters characterized by high nonlinearity and uncertainty. This paper presents a simulation of slope instability in an open-pit mine located in Guangdong Province, China, using the GDEM-GAVA method. Through an analysis of the source area, landslide mass, and the entire study area model, this research provides insights into the main development process of landslide disasters in open-pit mining areas, the characteristics of landslide mass movement paths, and the accumulation features in the severely affected areas. The findings reveal that the overall planar shape of the landslide mass in the open-pit mining area is elliptical, with the development process of the entire landslide accumulation area displaying two distinct zones: the upper step accumulation zone and the middle-lower step accumulation zone. The depth of the sliding body ranges from approximately 1 to 10 meters. The affected area spans about 420 meters in length, 100 meters in width, and 190 meters in height, with a maximum accumulation thickness of approximately 10 meters. The impacted area covers an approximate area of 40,000 square meters. These results can serve as a reference for subsequent safety production measures related to open-pit mine landslides caused by natural disasters.
