RECOVERY TECHNOLOGY OF BOTTOM COAL IN THE GOB-SIDE ENTRY OF THICK COAL SEAM BASED ON FLOOR HEAVE INDUCED BY NARROW COAL PILLAR

Recovery Technology of Bottom Coal in the Gob-Side Entry of Thick Coal Seam Based on Floor Heave Induced by Narrow Coal Pillar

To improve the resource recovery efficiency of mining face in thick coal seams, the correlation between deformation failure of bottom coal in the gob-side entry and coal pillar width was analyzed by theoretical analysis, numerical calculation, and similar simulation experiments.The results showed that, when the coal pillar was Lanyards strong, with
