An Overview of Slope Failure in Mining Operations

open access: yesMining, 2022
The primary aim of every twenty-first century mining operation is to extract as much ore as possible in a safe and economical manner. Failure in mine excavation occurs when the shear stress acting on the rock is greater than the shear strength of the ...
