In actual production, deep coal mine roadways are often under typical static-dynamic coupling stress (SDCS) conditions with high ground stress and strong dynamic disturbances. With the increasing number of disasters and accidents induced by SDCS conditions, the safe and efficient production of coal mines is seriously threatened. Therefore, it is of great practical significance to study the deformation and failure characteristics of the roadway surrounding rock under SDCS. In this paper, the effects of different in-situ stress fields and dynamic load conditions on the surrounding rock are studied by numerical simulations, and the deformation and failure characteristics are obtained. According to the simulation results, the horizontal stress, vertical stress and dynamic disturbance have a positive correlation with the plastic failure of the surrounding rock. Among these factors, the influence of the dynamic disturbance is the most substantial. Under the same stress conditions, the extents of deformation and plastic failure of the roof and ribs are always greater than those of the floor. The effect of horizontal stresses on the roadway deformation is more notable than that of vertical stresses. The results indicate that for the roadway under high-stress conditions, the in-situ stress test must be strengthened first. After determining the magnitude of the in-situ stress, the location of the roadway should be reasonably arranged in the design to optimize the mining sequence. For roadways that are strongly disturbed by dynamic loads, rock supports (rebar/cable bolts, steel set etc.) that are capable of maintaining their effectiveness without failure after certain dynamic loads are required. The results of this study contribute to understanding the characteristics of the roadway deformation and failure under SDCS, and can be used to provide a basis for the support design and optimization under similar geological and geotechnical circumstances.

在实际生产中，深部煤矿巷道通常处于典型的静动力耦合应力（SDCS）条件下，具有较高的地面应力和强烈的动态扰动。随着SDCS条件引发的灾难和事故数量的增加，煤矿的安全和高效生产受到严重威胁。因此，研究SDCS下巷道围岩的变形破坏特征具有重要的现实意义。本文通过数值模拟研究了不同地应力场和动载荷条件对围岩的影响，获得了变形和破坏特征。根据仿真结果，水平应力 垂直应力和动态扰动与围岩的塑性破坏有正相关关系。在这些因素中，动态干扰的影响最大。在相同的应力条件下，屋顶和肋骨的变形程度和塑性破坏程度始终大于地板。水平应力对巷道变形的影响比垂直应力的影响更为明显。结果表明，对于高应力条件下的巷道，必须首先加强原地应力测试。确定地应力的大小后，应在设计中合理安排巷道的位置，以优化开采顺序。对于受到动态载荷强烈干扰的道路，请使用岩石支撑（钢筋/电缆螺栓，钢套件等）。），在需要一定的动态载荷后，能够保持其有效性而不会失败。这项研究的结果有助于理解SDCS下巷道变形和破坏的特征，并可为相似地质和岩土情况下的支护设计和优化提供基础。
