Abstract: Progress in feature research topics in deep undergroundDeep Underground Science and Engineering (DUSE) is pleased to release this issue with feature articles reporting the advancement in several research topics related to deep underground.This issue contains one perspective article, two review articles, six research articles, and one case study article.These articles focus on underground energy storage, multiscale modeling for correlation between micro-scale damage and macro-scale structural degradation, mineralization and formation of gold mine, interface and fracture seepage, experimental study on tunnelsand-pile interaction, and high water-content materials for deep underground space backfilling, analytical solutions for the crack evolution direction in brittle rocks, and a case study on the squeezing-induced failure in a water drainage tunnel and the rehabilitation measures.The perspective article deals with the construction of the first underground energy storage complex in Xuzhou, China.This article entitled "Compressed air and hydrogen storage experimental facilities for sustainable energy storage technologies at Yunlong Lake Laboratory (CAPABLE)" (DOI: 10.1002/dug2.70043) reported the construction progress and technical development of lined rock caverns (LRC) facility for compressed air and hydrogen storage.This facility will focus on the verification of load transfer, damage and failure mechanism of the LRC structure, and the development of new materials for both lining and sealing layers.Three key problems for compressed air and hydrogen storage in underground spaces will be addressed: cavern stability, sealing efficiency, and minimum environmental impacts.One review article focuses on the genesis and preservation mechanisms of 10 000-m ultradeep dolomite reservoirs in China (entitled "Genesis and reservoir preservation mechanism of 10 000-m ultradeep dolomite in Chinese craton basin", DOI: 10.1002/dug2.12112).This is indeed the first article on ultradeep reservoirs published in the Journal of DUSE.Ultradeep dolomite reservoirs are particularly important for the future oil and gas explorations in China's marine craton basin.This review article systematically expounds the genetic mechanism and reservoir formation mechanism of ancient dolomite, clarified the limiting factors of dolomitization process and the preservation mechanism of dolomite reservoirs in deep buried environment, explored the spatial distribution of dolomite reservoirs, and identified the major zones of oil and gas exploration in 10 000-m deep layers.This article has no doubt provided the latest update on the fundamental knowledge for future oil and gas explorations in China.
