Influence Mechanism of Distribution Position of External Dumping on Stability of Composite Slope in Open-pit Coal Mine

open access: yesMeikuang Anquan, 2020
In order to clarify the influence of the location of the external dumping on the stability of the open-pit slope, a two-dimensional theoretical model of composite slope is established, and the formula for calculating the safety factor of end-slope ...

Tunnelling Induced ground settlement considering soil variability [PDF]

open access: yesInternational Journal of Mining and Geo-Engineering, 2023
Ground settlement need to be predicted well so that necessary precautionary measures could be adopted. Ground deformation behavior due to tunnel construction in inhomogeneous soil has been studied in the past few decades by many researchers.
