Aiming at the failure mechanism and control problem of surrounding rock of deep buried solid coal rectangular roadway under thick loose layer and thin bedrock overburden structure, the influence of horizontal stress on the surrounding rock load of this kind of roadway was studied through engineering field investigation, numerical simulation, theoretical derivation and case application. Taking Guotun Coal Mine as the engineering background, the failure characteristics of surrounding rock of solid coal rectangular roadway under thick loose layer and thin bedrock overburden structure were revealed. According to the ground stress characteristics of deep buried roadway, the arch axis equation of balanced arch considering horizontal stress was deduced based on the balance of force and moment. The calculation method of surrounding rock load of rectangular roadway based on the improved model of balanced arch was proposed and programmed, which improved the analysis theory of balanced arch. The effectiveness of the improved balanced arch model was verified by engineering examples and two research cases, and the influencing factors of the failure height of the roadway vault and the roof load were analysed. The results show that the failure of the surrounding rock at the top of the rectangular roadway presents three obvious zones, namely, the broken caving zone, the fracture affected zone and the non-affected zone. The error between the damage range of the vault and the side calculated by the proposed theoretical method and the numerical simulation results is 7.4% and 14.0% respectively, and the error between the proposed theoretical method and the field detection results of similar roadway is 25.0% and 18.4% respectively. The comparative analysis results of the two engineering cases verify the rationality of the improved model of the balanced arch. The failure height of the roadway vault and the roof load decrease nonlinearly with the increase of the lateral pressure coefficient, and decrease linearly with the increase of the internal friction angle of the fragmentation. The research results have important guiding significance for the design of bolt/anchor cable support in this kind of roadway.

针对厚松散层薄基岩覆岩结构下深埋实体煤矩形巷道围岩破坏机理与控制难题，通过工程现场调查、数值模拟、理论推导和案例应用，研究了水平应力对该类巷道围岩载荷的影响。以郭屯煤矿为工程背景，揭示了厚松散层薄基岩覆岩结构下实体煤矩形巷道围岩破坏特征；依据深埋巷道地应力特征，基于力和力矩平衡推导了考虑水平应力的平衡拱拱轴线方程，提出了基于平衡拱改进模型的矩形巷道围岩载荷计算方法并实现了程序化，完善了平衡拱分析理论；通过工程实例和两个调研案例验证了平衡拱改进模型的有效性，并开展了巷道拱顶破坏高度和顶板载荷的影响因素分析。结果表明，矩形巷道顶部围岩破坏呈现明显的三个分区，分别为破碎冒落区、破裂影响区和无影响区；本文所提理论方法计算得出的拱顶和帮部破坏范围与数值模拟结果误差分别为7.4%和14.0%，与类似巷道现场探测结果误差分别为25.0%和18.4%，两个工程案例的对比分析结果验证了平衡拱改进模型的合理性；巷道拱顶破坏高度和顶板载荷均随侧压系数的增大而呈非线性减小，随碎裂体内摩擦角的增大而呈线性减小。研究结果对该类巷道锚杆/锚索支护设计具有重要指导意义。
