Deformation Mechanism and Control Strategies of Gob-Side Entry Retaining by Roof Cutting in Ultra-Deep Coal Mines
Gob-side entry retaining by roof cutting and pressure relief (CRRE) eliminates coal pillar waste and mitigates mining-induced stress concentration. Although widely applied in mines shallower than 1000 m, systematic research on asymmetric deformation mechanisms and matched control technologies under ultra-deep condition...
