Physical Similarity Simulation of Overburden-Slope Deformation and Fracture Evolution Under Sequential Highwall-Mining Excavation at Different Chamber Heights
To reveal the evolution of overburden movement, slope deformation, and fracture damage during highwall mining, a physical similarity model was established based on the geological conditions of the Heishan Open-Pit Mine, Xinjiang. The excavation extended through the model thickness and was idealized as a continuous slot...
