摘要： 针对盖州矿聚能爆破切顶卸压沿空留巷围岩长期安全性方面的实际问题，详细分析了影响留巷围岩长期安全
性的因素，提出了切顶留巷因区而异、分区控制围岩结构以及全断面喷浆控制围岩风化的总体方案。通过该方案的应用，
成功将9107胶带顺槽聚能爆破切顶卸压沿空留巷作为一采区东翼回风巷，实现了一采区东翼工作面的安全高效回采。

Abstract: Aiming at the practical problem of long-term safety of surrounding rock in gob-side entry retaining for roof cutting and
pressure relief by energy-concentrated blasting in Gaizhou Coal Mine, this paper analyzed in detail the factors that affect the
long-term safety of the surrounding rock in gob-side entry retaining, and proposed an overall plan for cutting the top of the
retained roadway to vary according to the area, controlling the structure of the surrounding rock in different zones, and controlling
the weathering of the surrounding rock through full section grouting. Through the application of this scheme, the goaf retaining
roadway of 9107 belt channelling energy-concentrated blasting is successfully used as the air return roadway of the east wing of
the first mining area, realizing the safe and efficient mining of the working face of the east wing of the first mining area.

Key words: blasting roof cutting; gob-side entry retaining; surrounding rock safety
