We use simulated epidote/chlorite gouges and conduct fault shear experiments at conditions typifying the ∼4 km depth typical of deep geothermal reservoirs to explore the effect of epidote/chlorite content on frictional strength and stability. Results indicate...

... ABSTRACT: A comprehensive geomechanical assessment is carried out to investigate the upper pressure limit of CO2 injection for the depleted Frigg Sand oil reservoir in the Nini field, offshore Denmark. The mechanical stability of the Frigg Sand reservoir, shale caprock and key intersecting...

... in such projects, the frictional properties of the fault typically control fault rupture and seismic response (Ikari et al., 2011; Niemeijer & Collettini, 2014). Thus, detailed characterizations of the evolution of fault strength and stability under hydrothermal conditions are crucial in understanding...

... The stability of tunnel by the conventional excavation is treated based on a thought whereby the ground surrounding an underground opening becomes a load bearing structural component. The thought considers the activation of the support load of the ground and the interaction with the installed support system...

... stability performance compared to those with lower or no interlayer content. In the salt mine, the distance between the salt cavern and tectonic fault should be at least twice the maximum diameter of the cavern for safety considerations. The distance between the cavern roof and bottom should be greater than...

... ABSTRACT: Rock slope stability is a major concern in mega engineering projects, and it has been a major focus of engineering geology for over three centuries. The toppling failure mode is considered as one of the most complex and challenging to stabilize. The complexity of slope failures...

... ABSTRACT: Clarifying the mechanism of wellbore stability in broken formations is crucial due to the discontinuous deformation and stress characteristics of such rocks. Conventional continuum-based rock mechanics methods need to be improved for these formations. The discrete element method (DEM...

... ABSTRACT: The stability of underground structures, like mines and tunnels, has always been a major concern in the field of underground space development works. Reliable prediction of tunnel stability is a key challenge for tunnel engineering, especially when drilling in folded rock masses...

... ABSTRACT: Discrete fracture networks (DFN) are applied extensively in the design of underground spaces for both mining and civil infrastructure industries. DFN-based design tools enable discrete modelling of rock masses and kinematic stability assessments to be undertaken for design. When...

... ABSTRACT: In the design of room-and-pillar mine systems, the loading capacity of the pillar is equally as important as the stability of the roof and walls to preserve safe working conditions and commercial ore productivity. The optimized design of pillars requires an assessment...
