During the mining process of the N1100 working face in the No.3 coal seam of Lu'an Mine Yu-wu Coal Industry,the roadway roof deforms severely,and the ordinary anchor cable support method is diffi-cult to adapt to the large deformation and damage law of the roadway,which has seriously affected the safety production and economic benefits of the mine.This paper proposes a control technology for constant-resis-tance large deformation anchor cable reinforcement and support based on the production characteristics,geolog-ical conditions and mine pressure behavior law.It solves the problem of significant roof subsidence and se-vere deformation faced under the existing support conditions,bringing safe and efficient production benefits to the mine,and also providing technical reference for similar engineering activities.
