开展深埋煤巷围岩破坏机理及支护技术研究具有重要的意义，本文依托某矿403101工作面运顺支护项目，采用理论分析、室内试验、现场监测与测试和数值模拟相结合的方法，对深埋综放面煤巷围岩破坏特性及支护技术进行研究。主要内容和结论有： （1）采用室内试验对4#煤物理力学性质进行研究，得到4#煤物理力学参数。结合403101工作面运顺围岩破坏特征和矿区地应力测试结果，分析得到影响深埋煤巷围岩变形破坏的主要因素有围岩岩性、巷道埋深、水平应力大小、最大水平主应力与巷道轴向夹角、地质构造、回采动压及地下水。 （2）采用现场监测评价原支护方案，结果表明巷道围岩发生大变形，锚杆（索）受力超过其设计抗拉强度，围岩松动圈范围超过锚杆长度，现有的支护方案不能满足要求。 （3）结合深埋煤巷围岩破坏机理研究成果和支护设计原则，提出了采用空锚索孔卸压、补强锚杆（索）支护参数、锚杆采用木托盘和锚索采用槽钢加蝶形托盘让压的支护措施，采用理论计算与FLAC模拟计算得到锚杆（索）参数。 （4）采用现场试验对403101工作面运顺支护方案的可行性进行验证，结果表明巷道围岩稳定，本文提出的支护方案可行，研究成果对矿区类似工作面巷道支护参数设计具有一定的参考价值。

Study on failure mechanics and support technology for surrounding rock of deep coal roadway has a great of significance,this article depending on support project of a mine’s No.403101 work face haulage,theoretical analysis,laboratory tests,field monitoring and testing,numerical simulation method was adopted,failure characteristics and support technology for surrounding rock of deep coal roadway was studied,the main contents and conclusions: (1)Physical and mechanical properties of No.4 coal was studied by laboratory tests,we got physical and mechanical parameters of No.4 coal.Combined with failure characteristics of surrounding rock at No.403101 work face haulage and results of mine’s in-situ stresses test,deformation failure impact factors for surrounding rock of deep coal roadway have properties of surrounding rock,roadway depth,horizontal stress magnitude,the angle of maximum horizontal stress and roadway axial,geological structure,mining disturbance and groundwater. (2)Original supporting scheme was evaluated by using field monitoring, the results show that surrounding rock of roadway has large deformation, pressure of bolt(cable) is more than its design tensile strength, range of loose circle for surrounding rock is more than length of bolt,the original supporting scheme is not meet the requirements. (3)Combined with failure mechanism for surrounding rock of deep coal roadway and support design principles, it proposed pressure relief by using empty anchor hole, reinforcement of bolt (cable) support parameters,the support measures of make away pressure is wooden pallets of bolt and channel plus butterfly tray of anchor,bolt(cable) parameters was given by using theoretical calculation and FLAC simulation. (4)The feasibility of No.403101 work face haulage support program was verified by using field test, the results show that surrounding rock is stable,the proposed support program is feasible,result of the study has certain reference value for roadway support parameters design of similar mining workface in mining area.
