Green coal mining technique integrating mining-dressing-gas draining-backfilling-mining

Aiming to address the following major engineering issues faced by the Pingdingshan No. 12 mine: (1) difficulty in implementing auxiliary lifting because of its depth (i.e., beyond 1000m); (2) highly gassy main coal seam with low permeability; (3) unstable overlying coal seam without suitable conditi...
