Water inrush is one of the most dangerous disasters in coal mining. Due to the large-scale
mining and complicated hydrogeological conditions, thousands of deaths and huge …

Underground coal mining has a strong disturbance on surrounding rock strata, causing
inevitable water inflow into mined spaces, which seriously affects safety production. Mine …

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 …

Natural rock joint permeability deviates from the classic fluid flow governing equations due
to the inherent fracture surface roughness (ie, contact points, spatial correlation, matching …

This study investigates the nonlinear behavior of flow passing through 28 crack
topographies in concrete at various pressure gradients using water permeability test …

Fluid flow through filled rock fractures is relevant to numerous engineering applications and
geophysical processes. However, a proper understanding of the flow behaviors in filled …

This study experimentally and numerically investigated the influence of the inertial effect of
fluid flow on the non-Darcy coefficient (β). The results showed that the non-Darcy coefficient …

Fluid flow tests were conducted on four kinds of fracture intersections, namely straight
fracture intersection, buckling fracture intersection, crossing fracture intersection and …

Previous studies pointed out that the hydraulic aperture (bh) is solely dependent on the
geometric features of a fracture, independent of fluid inertia effects. Here we present an …

To investigate the effect of confining pressure P c on the seepage mechanism
characteristics, a new model of seepage mechanism characteristics coupling with confining …
