Thermo-hydro-mechanical coupling mechanisms and sensitivity analysis of abandoned mine thermal energy storage systems by Liyuan LIU, Yaohui LI, Tao WANG, Tongbin ZHAO, Qiang KOU, Zerui MI, Le ZHANG

“…A three-dimensional thermo-hydro-mechanical (THM) coupled numerical model is developed to calculate the coupled effects over a decade of system operation and analyze heat transfer processes along with stress variation patterns in the roadway’s surrounding rock. Results indicate that the MTES system effectively utilizes geothermal environments for high-efficiency storage of waste heat, achieving a residual temperature of 35.5 ℃ (44.4% retention rate) during the first year following the injection of 80 ℃ water, with winter extraction temperatures progressively increasing annually. …”
