Thermo-Hydro-Mechanical (THM) Coupled Model for Gas Extraction from Deep Coal Seams and Factors Influencing the Effective Extraction Radius
Gas extraction from deep coal seams is strongly affected by high geothermal temperature, high gas pressure, and high in situ stress, making accurate prediction of the effective gas extraction radius important for optimizing gas extraction parameters. In this study, a thermo-hydro-mechanical (THM) coupled model incorpor...
