Sample Rocks Tests and Slope Stability Analysis of a Mine Waste Dump

Abstract: The safety and stability of waste dump are vital influencing factors to the mine sustainability and mine employees. Based on a real mine project in a certain open-pit mine waste dump in Tibet, the in situ test on waste rocks from waste dump, including measurements of density, water content, rock size, and natural repose angle, was conducted. Afterwards, these sample waste rocks, of which grain size is less than 5 cm, were selected for indoor large-scale shear test under natural and saturated conditions. By usi… Show more

“…As an example, Zou et al [13] used a method coupling MIDAS and FLAC 3D to establish a 3D model of a waste dump; simulated the stress, displacement, and plastic zone distribution; and calculated the factor of safety (FOS). Tao et al [14] used the Fish language in 3DEC to establish a large deformation numerical analysis mechanical model of an NPR anchor cable.…”

“…Even though the safety factor of dump slope could be obtained by solving the limit equilibrium equations of the dump system, such safety factor cannot be used to describe the evolution of the slope, which usually involves large deformation of the dump materials. Over the years, the finite difference methods were also applied to analyze the stability of waste dump [5][6][7][8], but most of them were used to study the static problems, and only the evolution of potential sliding surface or plastic zone was obtained. Due to the large scale and height of the dumps, researchers usually use physical model tests to study their stability [9].…”
