Semi‐analytical solution for the stability of deep vertical shaft considering time‐dependent rock‐structure interaction

open access: yesDeep Underground Science and Engineering, EarlyView.
A novel cavity contraction solution and multilayer shaft wall model were developed to analyze deep shaft stability, considering rock viscosity, support structures, and water pressure, with successful validation through a Hulusu Coal Mine case study.

Critical technologies in the construction of underground artificial chamber for compressed air energy storage systems

open access: yesDeep Underground Science and Engineering, EarlyView.
This schematic illustrates an artificial chamber‐based compressed air energy storage system. Excess electricity compresses air into sealed underground chambers. During demand peaks, pressurized air is heated, expanded, and drives turbines to generate power.

Rainfall increases conformity and strength of species–area relationships

open access: yesEcography, EarlyView.
The positive relationship between species richness and area is regarded as one of the few laws in ecology. Therefore, deviations from predictable species–area scaling, evident as high residual variance in species–area curves, are often interpreted as anomalous behaviour.
