通过研究沿空巷道围岩稳定性影响因素和关键影响因素,得出了深井沿空巷道围岩稳定性控制的理论基础,对于巷道顶底板应采取有效地应力控制方法;对于巷道两帮必须采取有效地整体性维护。同时分析了深井沿空巷道围岩失稳机理及其覆岩大、小空间结构的稳定性,进而提出了深井沿空巷道围岩控制的对策及方法,对深部矿井沿空巷道围岩稳定性的维护具有重要的指导作用。
By studying the influencing factors and the key influencing factors on the surrounding rock stability of the gob-side entry, the theoretical basis for the surrounding rock stability control of the gob-side entryway is obtained. For the top and bottom of the tunnel, effective stress control methods should be taken; Effective overall maintenance. At the same time, the instability mechanism of the surrounding rock of the roadway along the deep mine and the stability of the large and small overburden strata are analyzed, then the countermeasures and methods of surrounding rock control of the roadway along the deep mine are put forward. The maintenance has an important guiding role.
