Roof-cutting pressure-relief effects and surrounding rock control technology for narrow-pillar gob-side entry driving in extra-thick coal seams with hard roofs

Frontiers in Earth Science
During fully mechanized top-coal caving in an extra-thick coal seam under a hard roof, suspended structures formed by multiple hard strata generate concentrated loads. Together with plastic failure of a narrow coal pillar, these loads exacerbate gob-side
