Governance of abandoned mines has become a pressing issue for China. The utilization is technology that can solve the problem governance and recreate value mines, which in line with current strategic goals ecological protection double carbon In this paper, various models advances rock mechanics across globe are summarized reviewed. be categorized into four aspects: Energy storage, Waste treatme...

The rock masses in a construction site of underground cavern are generally not continuous, due to the presence of discontinuities, such as bedding, joints, faults, and fractures. The performance of an underground cavern is principally ruled by the mechanical behaviors of the discontinuities in the vicinity of the cavern. During underground excavation, many surrounding rock failures have close r...

The traditional Three-dimensional (3D) model for stability analysis of a large underground cavern group only includes the main powerhouse, transformer chamber, tailrace surge tank, electrical wire hall, and part diversion tunnel tailwater tunnel. Other caverns excavation are not taken into consideration, which is inconsistent with actual project. In this study, 3D Finite Element Method (FEM) mo...

Caverns are generally formed by a combination of regional geological action and groundwater, their improper treatment will inevitably lead to dangerous conditions in underground works. To detect the specific failure mechanism tunnel-surrounding rock induced invisible caverns, true triaxial compression test is conducted, accompanied acoustic emission technology an internal borehole camera, for m...
