Understanding the fluid flow mechanisms in fractured porous media plays an important role in many engineering activities, such as nuclear waste disposal, geothermal energy extraction, oil and natural gas production, as well as performance and safety of underground projects including coal mines and tunnels. In recent years, many methods including numerical simulation, laboratory experiment, and theoretical analysis have been employed to investigate the flow process and permeability response of rock fractures, from kilometer scale to microscale. However, the rocks/coals are in deep underground that is very complex and exists some uncertainties. Therefore, new numerical simulation methods and deep explanations of fluid flow behaviors in fractured porous media are still needed.

This special issue aims at presenting recent advances in studies on the 3D fracture network reconstruction, fluid flow modeling and permeability estimation of rock fractures. We invite you to submit comprehensive review papers and original articles. 

Potential topics include but are not limited to the following:

• Intelligent and secure face recognition system in Smart Cities

• Reconstruction of 3D rock fractures and permeability estimation

• Fluid flow and solute transport in fractured porous media

• Flow regime transition modeling in complicated fracture networks

• Usages of 3D printing, micro-CT scanning and scanning electron microscope (SEM) techniques

• Fracture shear behavior and shear-flow process

• Effects of thermal treatment on dynamic and physical properties of rocks

• Stability control modeling of underground surrounding rocks

  • Experimental and Numerical Study on Anchorage Strength and Deformation Properties of Blocky Rock Mass
  • Abstract This study experimentally and numerically investigated the anchorage properties, bolt force evolution, deformation and stress fields of blocky rock mass with various dip angles of joint surfaces under an applied axial load. The results show that due to bolt reinforcement, the axial stress-strain curves of anchorage blocky rock mass show typical strain-hardening characteristics, and compared with models without anchorage, the peak strength and elastic modulus increase by 21.56% and 20.0%, respectively. With an increase in axial stress, the lateral strain continuously increases, and restriction effects of bolts reduce the overall deformation of model surfaces. The axial stressstrain curves of anchorage… More
