Abstract The large deformation and strong rheological characteristics of the underground rock body under complex geological conditions have led to the failure of the support system and even the instability of tunnels from time to time. Based on the t

Earth dams must be supplied with seepage control devices to prevent piping and sloughing. One such device used for this purpose is the so-called drain pipe. This study focuses on the influence of drain pipes on seepage and slope stability analysis in

In order to investigate the non-Darcy seepage characteristics of crushed gangue filling in the goaf under the action of the overlying rock layer, the self-developed crushed rock seepage test system is utilized to carry out uniaxial lateral limit comp

The radial gas seepage flow regime of the coal body around borehole is one of important factors reflecting the seepage movement of extracted gas. In order to investigate the effects of different pore structures and gas pressure on the radial seepage

Faults and collapse columns are some of the main hidden dangers affecting the coal mining above confined aquifers, which structure is composed of crushed stones and argillaceous fillings (mud-rock slurry), and thus is very complex. Therefore, the det

Existing methods for calculating the ultimate support pressure of tunnel faces do not consider the control of seepage flow. Therefore, a model for calculating the ultimate support pressure under seepage conditions was established based on a two-dimen

Using one opening (filter) within the floors of hydraulic structures is a known technique to relieve the seepage effects on their floors. In this study, a new method to control seepage flow by using two identical filters instead of one was tackled nu

This paper focuses on the influence of permeability anisotropy of seepage flow on the face stability for a shied tunnel. An analytical model has been proposed to present the hydraulic head distribution around the tunnel face in the anisotropic ground
