摘 要:基于皇后煤矿采掘巷道受淋水影响,围岩软化现象严重,锚杆(索)支护强度低等问题,以15108回风顺槽为研究对象,采用理论分析和现场实践相结合的方法,选取梁式耦合加固技术对巷道顶板进行加强支护,并对巷道顶板控制效果进行分析。结果表明,在采用梁式耦合加固技术控制顶板后,减少了巷道修复次数,降低了劳动作业强度及支护成本费用。Based on the technical problems of Queen's Coal Mine,the softening phenomenon of surrounding rock is serious due to the influence of drenching,and the strength of anchor rod(cable)support is low.Taking 15108 backwind downtrack as the engineering background,using the method of combining theoretical analysis and on-site practice,beam coupling reinforcement technology is selected to strengthen support for the roadway roof,and the effect of roadway roof control is analysed.The results show that after using the beam coupling reinforcement technology to control the roof plate,the number of roadway repairs is reduced,and the labour intensity and support costs and expenses are reduced.
