Study on the Energy Evolution and Stability of Roadway Surrounding Rock Under the “Simultaneous Mining–Driving” Condition

Energy Science &Engineering, Volume 14, Issue 4, Page 2225-2247, April 2026.
Based on theoretical analysis, the energy‐evolution behavior of the surrounding rock at various depths on the solid‐coal side of the 221303 material roadway during the “advancing‐toward‐mining” process was first clarified. Numerical simulations were then performed to validate and elaborate on the theoretical results.

Floor Heave Mechanism of Gob-Side Entry Retaining with Fully-Mechanized Backfilling Mining

, 2017
Serious floor heave in gob-side entry retaining (GER) with fully-mechanized gangue backfilling mining affects the transportation and ventilation safety of the mine. A theoretical mechanical model for the floor of gob-backfilled GER was established.

Study on Damage Characteristics and Evolution Law of Macro‐Meso Structure of Surrounding Rock Under Mining Stress

Energy Science &Engineering, Volume 14, Issue 4, Page 2024-2039, April 2026.
Investigating the differential impact of mining stress on roadways, we find that in horizontally stressed environments, the inner surrounding rock exhibits more pronounced macro‐meso damage compared to the outer side. ABSTRACT The control of surrounding rocks in dynamic pressure roadways has consistently been one of the challenging predicaments in the ...

Fault Friction, Plate Rheology, and Mantle Torques From a Global Dynamic Model of Neotectonics

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract Improvements in software, parallel computing, global data sets, and laboratory flow‐laws help to develop the global Earth5 thin‐shell finite‐element model of Bird et al. (2008, https://doi.org/10.1029/2007jb005460) into a benchmark study. All experiments confirm that modeled faults (other than megathrusts) have low effective friction of 0.085 ±

Decoupling Hydroclimatic Controls on Displacement of Retrogressive Thaw Slumps in Qinghai‐Tibet Plateau

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract The retrogressive thaw slumps (RTS), a prevalent form of thermokarst hazard in permafrost regions, are increasing in both number and extent under contemporary changing environments. On the Qinghai‐Tibet Plateau, RTS threaten transportation infrastructure and disrupt ecosystems.
