Implication

Analysis reveals tensile strength significantly impacts fracture zones and permeability in heterogeneous coal, indicating crucial modeling implications.

Key Points

Fracture propagation and permeability are heavily influenced by tensile strength and its variability.
Key metrics include a damage area difference of 10.094 and a high tensile strength coefficient of variation (0.85).
The analysis employed a thermo-hydro-mechanical-damage coupling model using COMSOL Multiphysics and MATLAB.
Variability in tensile strength may enable better identification of hydraulic fracturing patterns in coal seams.
