Failure mechanism of the coal wall at the working face based on an eccentric compression mechanical model

Deep Underground Science and Engineering, Volume 5, Issue 1, Page 127-143, March 2026.
In this study, the nonuniform distribution of the bearing pressure in front of the coal wall has been revealed based on in situ monitoring data and numerical simulation results. Therefore, an eccentric compression mechanical model of the coal wall was established to study the deformation and failure characteristics of a coal wall. The slenderness ratio

Study on the Evolution of Concentrated Stress Distribution in Close‐Proximity Coal Seam Residual Pillars

International Journal of Energy Research, Volume 2026, Issue 1, 2026.
Closely spaced coal seams are extensively distributed across China. As shallow coal resources face increasing depletion, coal mining is gradually extending to deeper zones. Deciphering the stress distribution pattern of the residual coal pillar floor in closely spaced coal seams is of profound importance to the safe and efficient mining operations of ...
