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

open access: yesInternational 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 ...
