Estimating bench design parameters for open-cut excavation

Abstract

"There are no direct relationships available that provide a basis for bench design of multiple-bench, open-cut earth excavations in competent materials when power shovels are employed. This study was undertaken to determine if mathematical design expressions could be developed when the production rate, material's properties, and equipment operating characteristics were known.

It was found that all bench dimensions were a function of the bench height, which in turn was controlled by the required rate of production. The investigation revealed that suitable relationships could be developed to guide in the control of bank stability, choice of shovel capacity, determination of the drilling and blasting design parameters, and selection of the necessary bench dimensions for efficient operation"--Abstract, page i.
