Performance evaluation of large scale rock-pit seasonal thermal energy storage for application in underground mine ventilation
TLDR
In this paper, a three-dimensional unsteady local thermal non-equilibrium model is developed to evaluate thermal storage and heat transfer between ventilation air and rock-pit, and the results suggest that the seasonal thermal energy storage of rockpit is able to assist thermal management in underground mine and to reduce energy consumption for winter heating and summer cooling.About:
