Abstract

fetched live from OpenAlex

Open pit mining projects usually face particular situations while dealing with slope stability analysis.More than any other projects, mining projects build a considerable number of slopes, which are more likely to behave differently among them, due to the change in orientation in the open pit.One of the situations that represent a considerable problem is the presence of a weak layer, which could be easily analyzed by using the limit equilibrium methods.Nonetheless, there are some practical measures that mining engineers take in order to improve the slope stability condition of mining slopes involving a weak layer, which consist in creating a disturbance in the rock medium surrounding the weak layer by blasting a strip of the rock mass.That modification of the rock medium is not easy to analyze with traditional limit equilibrium methods, because there is not a constitutive model to properly characterize that portion of the disturbed medium.This paper presents a first approach to analyze the stability in open pit mining slopes in the presence of a weak layer, both, before and after blasting to create a disturbance of the medium.This approach considers the effect of the rock mass disturbance, by using a combination between data coming from inclinometer monitoring in the slopes and numerical simulations with finite elements, which allows to monitor the slope stability during the rock mass disturbance.The disturbed rock mass, known as "bimrock", is then characterized and included into the slope stability models to obtain the factor of safety considering the disturbance of the medium.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
