|The operation of mobile mining equipment near the crest of stockpiles and wastedumps often results in localized slope failures. The Bureau of Mines has developed a computer code based on a rigorous limit plasticity approach which determines the admissible total weight for a concentrated loading near the crest of these otherwise stable structures. The program is based on a three- dimensional analysis and provides an upper bound solution to the load that can be applied to the top of the operating distances for mobile equipment from the slope edge. This presentation will discuss the application of limit plasticity to the development of the local three-dimensional collapse mechanism, and the use of the computer code based on this approach for mining applications.|
