基于顾桥矿深部巷道围岩变形量大、岩移速度快、破裂形态不规则的特点，采用数值模拟和理论分析的方法研究了深部围岩变形破坏的力学机理，得到了围岩塑性区的分布范围和扩展空间，揭示了围岩位移场的变形特征和围岩应力随机产生、连续变化、实时调整及动态发展的演化规律，相应提出了巷道稳定性控制的技术措施，即巷道断面全封闭支护技术、“三锚”组合强化支护技术和锚梁网索耦合让压联合支护技术。通过顾桥矿1114（3）工作面巷道支护的工程实践，有效控制了围岩变形，取得了良好的支护效果。

Aiming at the characteristics such as large deformation , fast displacement ,irregular fracture pattern of surrounding rocks of roadway at great depth in Guqiao Coal Mine , the mechanism of mechanical deformation and failure of rock mass was studied by using the methods of numerical simulation and theoretical analysis .Distribu-tion range of the plastic zone in surrounding rocks and expansion of space were obtained , the evolution law of stress generated randomly , continuous change , deformation characteristics of surrounding rock displacement field, the real time adjustment and dynamic development were revealed .The technical measures for roadway sta-bility control were put forward , such as roadway closed supporting technology , composite reinforced supporting technology with bolt , anchor cable and anchor spraying , and the combined supporting technology with anchor , beam and mesh cable coupling .The engineering practice of roadway support in 1114 (3) working face of Guqiao Coal Mine showed that by using the method , the deformation of surrounding rocks is effectively controlled , and the supporting effect is good .
