An ANN–Driven Excavatability Chart Integrating GSI and Rock Mass Strength

Applied Sciences
Excavation is a common requirement in engineering construction within rock masses. While excavation volumes are generally limited in road slope projects, they may become substantial in large-scale operations such as deep open pit mines.

Determination of Distance Required to Ensure Stope and Footwall-drift Non-interaction Zone based on Geological Strength Index

Earth Sciences Research Journal, 2019
In the Bakibaba Copper Mine, the longhole stoping method is used in the production of copper ore. Stability problems have occurred at times on the footwall drift due to the interaction between the footwall drift and stope.

Relating in situ hydraulic conductivity, particle size and relative density of superficial deposits in a heterogeneous catchment [PDF]

, 2012
Estimating the permeability of superficial deposits is fundamental to many aspects of catchment science, but can be problematic where insufficient in situ measurements are available from pumping tests in piezometers.

Assessing the critical material constraints on low carbon infrastructure transitions

, 2013
We present an assessment method to analyze whether the disruption in supply of a group of materials endangers the transition to low-carbon infrastructure. We define criticality as the combination of the potential for supply disruption and the exposure of

Scale Considerations and the Quantification of the Degree of Fracturing for Geological Strength Index (GSI) Assessments

Applied Sciences
This paper provides research that shows that the scale and quantification of the degree of fracturing in a rock mass should and can be considered when estimating geological strength index (GSI) ratings for rock mass strength and deformability estimates ...
