Study on the Influence of Slope Static Load on Shallow Lining Support Structure

Energy Science &Engineering, Volume 14, Issue 6, Page 2721-2735, June 2026.
On the basis of the background of the shallow‐buried main adit supported by stone lining, the mechanical model of the supporting structure is constructed, and the stability of the supporting structure is analyzed by using the methods of field investigation, theoretical analysis, and numerical simulation.

Experimental Study on the Floor Heave and Failure Process of Rock Samples under Biaxial Step Loading

, 2023
Floor heave is a typical tunnel issue in tunnelling engineering. To gain deep insights into the deformation mechanism and failure processes of floor heave at the bottom of a tunnel in layered rock, biaxial step-loading tests were conducted on rock ...

Research and application of surrounding rock control technology for gob-side upper entries in fully mechanized caving faces of thick coal seams with large dip angles

Results in Engineering
The 13040 working face in Xinmi Hengtai Mine presents a thick coal seam, high dip angle, and a thick, hard roof, which challenge the upper gob-side entry with poor stability, support failure, and severe rib deformation.

Advancing Robust Governance in Turbulent Times: The Role of Multi‐Level Governance, Hybrid Governance, and Negotiated Societal Intelligence

Public Administration, Volume 104, Issue 2, Page 251-265, June 2026.
ABSTRACT New research argues that robust governance based on flexible adaptation and proactive innovation is needed in order to uphold core public functions, purposes, and values in times of societal turbulence. However, we have limited knowledge of the conditions for enhancing robust governance.

Similar Material Simulation Study on Dam Movement and Deformation Law of Deep Coal Seam Mining Under Dam

Energy Science &Engineering, Volume 14, Issue 4, Page 1808-1821, April 2026.
Aiming at the difficulties in accurately calculating the movement and deformation of small‐sized, deep‐buried dams with a significant height‐to‐depth ratio in deep fully mechanized caving mining, this study proposes to separate the analysis of surface and dam deformation.
