Coupled thermo-hydro-mechanical modelling for geothermal doublet system with 3D fractal fracture

Jia Liu et al.

Summary: The study demonstrates that the thermo-hydro-mechanical coupling model considering the deformation of fractal fractures is remarkably robust for modeling fracture opening and closing under coupling conditions. The evolution of fracture permeability presents certain heterogeneity related to fractal dimension, in-situ stress, and geothermal wells layout. Fractures with larger fractal dimension can interact more fully with the bedrock and further affect the thermal breakthrough.

Investigation of the influence of gas fracturing on fracturing characteristics of coal mass and gas extraction efficiency based on a multi-physical field model

Yi Xue et al.

Summary: A hydro-mechanical coupling model is established to analyze the damage characteristics of coal seams during gas fracturing, focusing on fracture criterion, post-peak strain softening, and non-uniform stress state influences. The differences between gas fracturing (nitrogen, CO2) and hydraulic fracturing are studied based on this model, with factors like compression coefficients, viscosities, and coal permeability affecting fracturing pressure.
