Water and mud inrush is one of the most important geohazards in underground engineering.
The paper presents a state-of-the-art review of the current understanding of this type of …

Fracture surface morphology significantly affects fluid flow in rock fractures and has attracted
considerable attention in many seepage-related fields. Fluid flow in rough-walled fractures is …

Water inrush hazard is a major threat to safe mining and tunnel construction. During the
water inrush process, nonlinear properties of rock mass can change gradually due to the …

This study focuses on experimental evaluation of the Forchheimer equation coefficients for
non-Darcy flow in deformable rough-walled fractures. Water flow tests through twelve granite …

Transition of fluid flow from the linear to the nonlinear regime has been confirmed in single
rock fractures when the Reynolds number (Re) exceeds some critical values, yet the …

This study experimentally analyzes the nonlinear flow characteristics and channelization of
fluid through rough-walled fractures during the shear process using a shear-flow …

This study focuses on the transport properties and permeability evolution characteristics of
fluid flow through thermally treated rock samples containing single fractures. First, splitting …

To understand the influence of shear behavior on the transporting properties of fluid through
a single fracture, splitting fractures were made in the laboratory and shear flow tests were …

The nonlinear flow behavior in a single rock fracture (SRF) has been studied for decades.
However, the existing models to link fracture geometries and nonlinear flow behavior are …

In this study, the low-field nuclear magnetic resonance (NMR) testing technique was
adopted to experimentally investigate the seepage processes of chemical grout flow in …
