... dumps (Fig. 1). The earth materials are heterogeneous and loose geomaterials that consist of particles varying widely in sizes, ranging from boulder to clay (Gao et al., 2017; Shrivastava et al., 2021). The dump materials are stacked into layers in the nearby areas, and management of these dumps...

... Abstract The discrete element method is widely used in rock mechanics, but its computational efficiency limits its development. To improve the accuracy of a discrete element model, the particle size of the entire model needs to be decreased according to the current theory. However, only...
