Stress Distribution and Evolution Characteristics of Hard–Soft Interbedded Floor Strata Subjected to Coal Pillar Loading

To reveal the stress transfer mechanism of overlying coal pillar loads in hard–soft composite floor strata during close-distance coal seam mining, this study comprehensively employed theoretical analysis, similar material simulation, and numerical simulation to systematically investigate the floor stress distribution c...

Failure mechanism of gob-side entry in weakly cemented soft rock and bolt-grouting collaborative control method: a case study.

During coal mining in western China, soft rocks with low strength, poor cementation, and a tendency to disintegrate upon water exposure are often encountered. This makes bolt support unable to maintain long‑term roadway stability, resulting in severe roadway deformation and failure. To solve this challenge, this manusc...
