The number of underground tunnels used for transportation has markedly increased globally
during the past decade. This has resulted in an increased number of tunnel fire incidents …

Step-path failure is a typical damage mode of rock slope featuring intermittent joints. In order
to investigate the effect of water-fracture interaction on the stepped failure, laboratory …

Intelligent rock bolts can be used in mining operations to acquire information on the bolt's
status and movements of the rock mass. The future value of this technology resides in …

To investigate the acoustic and mechanical properties of shale gas reservoir rocks, fracture
experiments under triaxial compression were conducted using Sinian shale samples …

Failure of brittle rock is often progressive and understanding the fracture development
process within rock masses is important to identify the precursors of failures. Joints in rock …

Frictional behaviour of rocks from the initial stage of loading to final shear displacement
along the formed shear plane has been widely investigated in the past. However the effect of …

Fractures control the hydro-mechanical behavior of rock masses. Explicit numerical
analyses require detailed information on fracture properties, spacing, and orientation. This …

The geometry of hydraulic fracture propagation in the absence and presence of natural
fractures in reservoirs was studied. The results revealed a marked influence of natural …

Mechanical behavior of rock with a single non-persistent joint was studied by numerical
simulations using two-dimensional Rock Failure Process Analysis (RFPA 2D) software. A …

The process of hydraulic fracturing makes use of a liquid to fracture reservoir rocks for the
exploitation of unconventional resources. Hence, it is vital to understand the processes that …
