关键词：Elastic and elastoplastic analysis of surrounding rock in CAES chambers considering excavationinduced centripetal exponential reduction mechanical properties
摘要：AbstractCurrently, there is a lack of research on the impact of excavation damage on the stability of underground compressed air energy storage (CAES) chambers. This study presents a comprehensive analytical framework for evaluating the elastic and elastoplastic stress fields in CAES chambers surrounding rock, incorporating excavation-induced centripetal reduction of rock stiffness and strength...

关键词：Stability analysis of a compressed air energy storage cavern transformed from horseshoeshaped roadway in an abandoned coal mine
摘要：AbstractCompressed air energy storage (CAES) caverns transformed from horseshoe-shaped roadways in abandoned coal mines still face unclear mechanisms of force transfer, especially in the presence of initial damage in the surrounding rock. The shape and size of the initial damage area as well as their effect on cavern stability remain unclear. Due to the complex geometry and multiphysical coupli...

关键词：Study on the diffusion and migration law of CO sequestrated in abandoned coal mine goaf
摘要：AbstractThe potential for CO2 sequestration in the goaf of abandoned coal mines is significant due to the extensive fracture spaces and substantial residual coal present. Firstly, the adsorption characteristics of residual coal in goaf on CO2 were studied by the isothermal adsorption test of CO2. Then, to accurately calculate the amount of adsorbed CO2 within the residual coal in the goaf, the ...

关键词：Critical technologies in the construction of underground artificial chamber for compressed air energy storage systems
摘要：AbstractCompressed air energy storage (CAES) has emerged as a grid-scale energy storage linchpin, providing diurnal-to-seasonal timescale energy buffering for renewable power integration. Diverging from conventional salt cavern-dependent approaches, artificial cavern-based CAES unlocks geographical adaptability through engineered underground containment. This study systematically reviews critic...
