Acoustic monitoring of hydraulic stimulation in granites
… stimulation of low permeability EGS reservoir rock is widely employed to develop this resource and is generally required to make unconventional resources an economically viable resource. Significant challenges for EGS technology include poor connectivity between injection and production wells …

Variations in mineral abundance within a single horizontal well path in the Woodford Shale, Arkoma Basin, Oklahoma
… in many geochemical, mineralogical, and rock mechanic properties across the state of Oklahoma, which presents a challenge to successful exploitation of this resource (Caldwell, 2014; Turner et al., 2015; Wiley, 2015; Zhang et al., 2017). Most prior studies of the Woodford Shale report …

Evaluation of strata conditions and performance of support systems of the Emerald Shaft Gold Mine in Gauteng Province of South Africa
… excavations causes disturbances in the rock mass, leading to geotechnical uncertainty and increased risk of fall of ground or backbreak. The incompetency of the rock mass, high tensile fractures, and concentration of horizontal virgin and mining-induced stresses pose significant threats …

Mechanical properties and microcracking behaviour of heterogeneous rocks after high-temperature treatment
… of the national economy. However, deep rock masses are typically subjected to complex environmental conditions, including high temperatures, and exhibit inherent heterogeneity. These factors significantly influence their strength characteristics and damage evolution mechanisms. In deep …

Combined finite-discrete element modelling of key instabilities which characterise deep-seated landslides from massive rock slope failure
The expression “landslide from massive rock slope failure” (MRSF) is used to indicate large-scale landslides characterised by a variety of complex initial failure processes and unpredictable postfailure behaviour. In this context, deep-seated landslides are classified as “landslides from massive …
