摘要：AbstractDouble-wheel trench cutters display reduced efficiency while cutting through hard or extremely hard rock strata, leading to significant wear on their picks. A high-pressure water jet-pick combined rock-breaking method (HPC) for double-wheel trench cutters is proposed, addressing the challenges of low efficiency and high pick wear when cutting hard rock strata. The HPC mode integrates hi...

关键词：Damage modeling of CO injection well interfaces under coupled thermal hydraulic and mechanical behavior
摘要：AbstractThis paper presents an investigation of well integrity during low-temperature CO2 injection using a model of thermo-poroelasticity with interface damage mechanics. The casing–cement and cement–formation interfaces are described using cohesive interface elements and a bilinear traction–separation law. Verification testing is performed to establish the correct implementation of the cou...

关键词：Gels for CO geostorage and conformance control A systemic review of behavior performance
摘要：AbstractCarbon capture and storage (CCS) remains one of the most feasible techniques for the control of Greenhouse gas emission levels. However, there will always be risks attached to the subsurface injection of CO2. These could be in the form of leakages from the injection wellbore due to completion failure; escape of the injected CO2 to neighboring aquifers due to the heterogeneous or fractur...

关键词：A review on rockburst prediction and prevention to shape an ontologybased framework for better decisionmaking underground excavations
摘要：AbstractWith underground engineering projects becoming deeper and more complex, the associated safety problems, especially rockburst, have increasingly increased. Despite decades of research, effective management of rockburst continues to be a formidable challenge in underground excavations. This study presents a scientometric visualization analysis of 2449 papers and conducts a comprehensive r...
