Implication

Simulation model demonstrates operational factors govern mechanical stability in mine water heat storage, suggesting regulatory monitoring could mitigate structural risks.

Key Points

Cyclical heat injection and heat extraction alter mechanical stability in mine water heat storage systems, with overall risk declining at reduced temperatures.
Simulation of room and pillar workings via a thermo-hydraulic-mechanical model shows injection temperature and water level drive displacement more than geology.
Framework insights support regulatory standards for mine water heat storage, potentially mitigating geomechanical failure risks in active geothermal schemes.
