Stress and deformation evolution characteristics of gob-side entry retained by the N00 mining method

The N00 mining method, as a novel coal mining technology, differs greatly in both the mining process and key technologies from traditional coal mining methods. To maintain entry stability under such new mining conditions, the stress and deformation process of the rocks surrounding the entry were analyzed based on the Mohr–Coulomb theory in this paper. The following results are concluded: the surrounding rocks of the entry formed with the N00...
