Stability control of gob-side entry retained under the gob with close distance coal seams
In multi-seam mining, the interlayer rock strata between the upper coal seam (UCS) and the lower coal seam (LCS) appear damage and strength weakening after mining the UCS. Ground stability control of the gob-side entry retaining (GER) under the gob with close distance coal seams (CDCS) is faced with...
