Predictive Index for slope instabilities in open pit mining

Jul 11, 2016 . Abstract: In this paper we study the stability and deformation of structures, in particular the wall of an open pit mine is studied by using information obtained from a variety of remote sensors and some extra data, with a novelty approach considering the use of mathematical models and data mining techniques.

Large Scale Slope Stability - Literature Review - TR . - DiVA portal

this report, the stability and design of large scale pit slopes in open pit mining is reviewed, with special reference to .. economic pit limit and the most economical mining program for a given mineralization (Steffen et al., 1970). The approach to open pit mine planning can be divided into two major phases; pit optimization.
