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 …

Selecting appropriate governing equations for fluid flow in fractured rock masses is of
special importance for estimating the permeability of rock fracture networks. When the flow …

Understanding the shear-induced evolution of aperture size is critical for controlling fracture
permeability in rock engineering projects. This study reports a robust procedure to evaluate …

To understand the influence of shear on the hydraulic properties of rock fractures, shear-flow
tests were carried out on rock fractures with different surface roughnesses. Each rough …

This study aims at understanding the mechanism of heat extraction from a geothermal
reservoir characterized by rough-walled fracture networks. A unified pipe-network method …

The single-fracture seepage model is important for fracture network seepage models and
underground engineering, but the existing knowledge is insufficient for the roles of the high …

Abstract T he 3D Unified Pipe-Network Method (UPM) is applied to simulate the acidizing
process in fractured carbonate rock. Fractures and porous media are represented by their …

An evaluation of published laboratory studies of flow through single rough fractures was
conducted to establish a relationship between aperture (2b) and critical Reynolds number …

Permeability modeling of filled fractures, in contrast to porous media and rough fractures,
has long plagued the hydrology and energy industries. Non-Darcy flow occurs in filled …

There has been a growing interest in the study of low-velocity non-Darcy flow in tight
reservoirs. Most existing non-Darcy equations, however, are flawed in model assumption …
