摘　　要：本文以石垭口煤矿深埋软岩巷道为工程背景,针对围岩大变形、支护体破坏严重及返修工程量大等难题,以软岩工程力学为理论指导,明确了巷道围岩的HJS复合型软岩类型,分析了HJS复合型软岩稳定性力学转换机制,提出了深埋软岩巷道恒阻大变形耦合控制技术,并开展现场工业性试验。现场监测数据验证了该技术的可行性,可为类似条件下深埋软岩巷道稳定性控制提供借鉴。Based on the engineering background of deep soft rock roadways in Shiyakou coal mine, in view of the large deformation of surrounding rock, the supporting body destroyed and great project of repair problems, such as guidance on the theory of soft rock engineering mechanics, the type of HJS composite soft rock of roadway surrounding rock is determined, and the mechanical conversion mechanism of stability of HJS composite soft rock is analyzed. Coupling control technology of constant resistance and large deformation of deep buried soft rock roadway is put forward, and industrial test in site. Field monitoring data verify the feasibility of this technique, which can provide reference for stability control of deep buried soft rock roadway under similar conditions.
