Due to the increasingly mining pressure in large mining depth working face ending recovery， pressing frame and roof caving are prone to happen. Roof control in large mining depth working face ending recovery of Liugou Mine was taken as example， through the analysis， the position and time of hanging net， support， roof hanging distance were the main reason for roof control difficulty. By increasing ending recovery mine pressure observation， making the reasonable position and time of hanging net and strengthening support， could effectively solve roof problem， pressing frame and roof caving in large mining depth fully mechanized ending recovery， so as to ensure the ending work of working face.
