Roof collapse accumulation and stress evolution characteristics of double-inclined mining in steeply inclined medium-thick coal seam

Roof collapse accumulation and stress evolution characteristics of double-inclined mining in steeply inclined medium-thick coal seam

The pseudo-inclined mining has limited capacity to reduce the inclination angle of working face, necessitating breakthroughs in longwall comprehensive mechanized mining methods for steeply inclined medium-thick coal seam with inclination angles exceeding 60°. Taking the 3212 working face in the Lüsh...
