... Abstract Thermal-hydraulic-mechanical (THM) processes in the geological disposal repository will continue for hundreds of years in the initial stage of disposal. The coupled processes influence the overpack displacement, the swelling behavior of the buffer, the deformation of the disposal hole...

... used by mining. The present study analyzed the chemical and mechanical behavior of the rock where an open pit was developed, considering a relation between the pH and the vertical and horizontal displacements of the slopes. It was observed that there is a close relationship with the decrease of the pH...

... mm/s and PPA = 0.08 g for the lowwall slope. In addition, unlike the PPA, the maximum permanent displacement is not that sensitive to the stability of the mine slopes under dynamic loading. 1 Introduction 1.1 Background Bench blasting is a common excavation method in open pit coal mines...

... deformation modulus, intact rock young's modulus and joint spacing. Similarly, the shear stiffness has been calculated. The results show the total displacement of 10.6 cm with a total velocity of 0.43 m/s for the same block in the numerical analysis. 1 Introduction The instability in the hilly region...

... of the rock mass is insufficient, the rock mass will be damaged and the rock mass will lose its resistance and cause a large displacement. Finally, it can lead to failure of the anti-slide pile (Wang Jinhui 2013). excavation university mechanics hunan province stability tensile strength southwest...

A dynamic module of stress-strain analysis was developed, based on finite element method displacement formulation, in order to estimate the variations in displacement, strain and stresses fields induced by blasting. From this study, it is possible to evaluate the effect of the detonation pressure...
