Roof-breaking mechanism and stress-evolution characteristics in partial backfill mining of steeply inclined seams
Steeply inclined seams buried at dip angles of 35–55° are considered hard-excavated seams in the mining industry. A partial backfilling method based on sub-regional features of surrounding rock deformations and failure and support stability was proposed to realize safe, efficient production, to prom...
