The characteristics of rock instability precursors and the principal stress direction are very
crucial for the prevention of geological disasters. This study investigated the qualitative …

Low heat transfer coefficient is a massive problem in the in-situ exploitation of oil shale.
Meanwhile, the formation of a fracture network is of great engineering significance to the …

The effect of bedding plane orientations on shear strength and failure mechanisms of shale
is investigated, with an emphasis on the shear parameters of the bedding planes. This study …

Shales are considered to be both source and cap rocks, and play an important role in
various geotechnical applications including oil and gas exploration and production. A deep …

This paper presents bonded-particle discrete element modeling with embedded smooth
joints for simulating the mechanical behavior of transversely isotropic rock with systematic …

Bedding planes or layers can have a serious effect on the mechanical behaviour of shale
rock. Fractures occurring along bedding planes form a fracture network in shale hydraulic …

When tunneling through deep-buried layered soft strata, asymmetric deformation of
surrounding rock and asymmetric mechanical behavior of supporting structures are often …

At present, shale gas plays a significant role in hydrocarbon reservoirs. Hydraulic fracturing
is generally employed in the exploration and exploitation of shale gas. Economic and …

The behavior of transversely isotropic rock material was studied under Brazilian test
conditions for nine different rocks (two sandstones, one shale, two slates, one schist, and …

Shale rock is widely distributed in nature and must be taken into account in some rock
engineering applications. In this research, three kinds of experiments, namely the …
