Synergistic Bearing Effect and Failure Mechanism of Backfill–Coal Pillar Composite Structure
Advances in Civil Engineering, Volume 2026, Issue 1, 2026.Constructing backfill walls adjacent to the yield coal pillar can effectively enhance its stability. The backfill and coal pillar form a synergistic bearing structure that jointly maintains the stability of the overlying strata. To reveal the synergistic bearing effect and failure mechanism of the backfill–coal pillar structure, this study first ...

Geofluids, Volume 2026, Issue 1, 2026.Floor heave control becomes more and more prominent in engineering practice with the increased mining depth of the working face. The gob‐side entry of the 21404 working face in Hulusu Coal Mine was taken to be the engineering background to study the gob‐side entry’s floor heave in the working face with a deep, thick, and dense layer of coal.
