摘　　要：针对甲玛矿区暂时稳定型高冒顶巷道的类型,分析了高冒顶巷道破坏的原因,提出了发泡材料充填控顶的技术方案。采用数值模拟方法,对高冒顶巷道发展过程及机制和发泡材料充填控顶的稳定性进行了分析评价。理论分析和现场实践证明,发泡材料对高冒顶巷道的充填控顶支护能够满足该类型巷道的稳定性和使用要求。Aiming at a temporarily stable tunnel with a high collapse in Jiama mining area,the reasons that cause a high collapse are analyzed and the technology scheme that foaming material is to fill and control roof is put forward.The collapse process and its mechanism of the tunnel is analyzed by numerical simulation,at the same time,the stability of foaming material to fill and control roof of tunnel is evaluated.Theoretical analysis and field practice prove that foaming material to fill and control roof of high collapse tunnel can satisfy the stability of this kind of tunnel and its use.
