This study explores how the topology-based measure of connectivity of a three-dimensional
discrete fracture network (DFN) can be used to predict flow channelization, a commonly …

The grand-scale suspended roofs overlying the goaf are commonly developed under thick-
hard rock strata (THRS) during the mining process of the deep coal seam. As a result, strong …

A discrete fracture network (DFN) model based on non-parametric kernel density estimators
(KDE) and directional-linear statistics is developed. The model provides a characterization …

Understanding the effect of loading rate on the normal deformation characteristics of joints
has been an important topic for rock dynamics and rock engineering activities. In this paper …

Weakly filled structural planes are an important influence on the stability control of
engineering rock mass. Weak fillings with different geometrical characteristics are randomly …

As coal resources are gradually being extracted at depth, the overlying strata movement
behavior and stress environment become complex and violent, leading to the frequent …

The freezing–thawing damage of rock mass involves the coupling of temperature field,
seepage field and stress field (THM) at low temperature. Based on water/ice phase transition …

The surface subsidence caused by the coal seam mining seriously affects the ecology of the
mining area. Compared with the single-coal seam mining, the mechanism of the overburden …

In order to explore the pressure relief effect of the two combined pressure relief and
antireflection technologies of ultra‐high pressure water jet cutting before pressure and …

As an unconventional natural gas, coalbed methane (CBM) has been recognized as a
significant fuel and chemical feedstock that should be recovered. Permeability is a key factor …
