| 摘 要： | 由于受到动压影响,矿井深部软岩巷道的围岩控制始终是矿山和岩石力学中的难题之一,特别是断层构造带的软岩巷道极易受到破坏,支护尤为困难.针对泉店煤矿东翼2条运输大巷的破坏特征,提出了二次高强补强支护技术方案,通过改善巷道围岩的各项力学参数提高围岩自身强度,有效抑制了巷道顶板的离层及围岩变形,取得良好的支护效果.

| Abstract: | Due to the impact of dynamic pressure,the surrounding rock control in deep soft rock roadway has always been a problem which is difficult to be solved in mine and rock mechanics.As the soft rock roadway is more vulnerable to be damaged,the supporting is especially difficult.In this paper,aiming at the damage characteristics of two transportation roadway in the east of Quandian Coal Mine,the plan of the second supporting was put forward.Through the optimization to the mechanical parameters,the strength of surrounding rock was improved,the bed separation and the deformation of surrounding rock in roadway were inhibited effectively. |
