Abstract: The fracture initiation location and expansion mode are important indexes to evaluate the fracturing effect during the hydraulic fracturing of a coal seam. However, the initiation location and propagation of hydraulic ...

Abstract: To better understand the shear stress distribution in rock-cemented discontinuities, such as bedding planes and mineral-filled natural fractures (NFs), subjected to direct shear, an analytical solution for shear stress was ...

Abstract: In order to investigate the compaction behavior of tight shale and obtain the apparent preconsolidation stress and critical stress of brittle-ductile transition, uniaxial strain tests were conducted at various temperatures. ...
