| 摘 要： | 各矿工作面终采线虽已按规定留设60 m以上保护煤柱，但工作面回采后附近巷道仍会受到采空区压力影响，从而有不同程度的变形受损，需对其进行修复。为减少采空区压力对附近巷道的影响，采用切顶卸压技术切断采空区顶板的应力传递，避免采空区压力破坏附近大巷，经济效益和安全效益显著。

| Abstract: | Although the protective pillars of over 60 m have been set up in the final mining line of each mining face according to the regulations，the roadways near the mining face will still be affected by the pressure of the goaf，and thus have varying degrees of deformation and damage，which need to be repaired.In order to reduce the influence of goaf pressure on nearby roadways，roof cutting and pressure relief technology is used to cut off the stress transfer of goaf roof and avoid the pressure damage of goaf to nearby roadways，the economic and safety effects are remarkable. |
