摘要为了有效地研究二次回采期间采场及巷道围岩稳定性，确保二次回采的整个过程中不会出现安全隐患，保证现场支护方案完善、合理，基于发耳煤矿50305工作面的地质状况，将50305工作面回采期间巷道围岩变形情况与采场应力进行系统地分析，从而使用合理的支护对策。通过理论分析，研究二次回采巷道顶板力学破断准则，提前确定破坏区范围。通过数值模拟，对工作面回采期间采场应力进行详细地分析，同时对巷道应力以及位移进行详细地分析，为二次回采期间使用合理的超前支护措施提供参考依据，确保安全开采。通过现场分析，分析二次回采期间巷道表面位移变形及液压支架荷载，观察现场应用效果以及是否存在不足之处，为其他矿井提供参考依据。二次回采巷道使用恒阻锚索、U型钢、临时支护共同协作的情况下进行支护，无煤柱自成巷二次回采效果良好。

Abstract：In order to effectively study the stability of mining face and roadway surrounding rock during the secondary mining period，to ensure that there will be no safety hazards in the whole process of secondary mining，and to ensure the perfect and reasonable on-site support scheme，based on the geological condition of the 50305 working face of Fa?er coal mine，the deformation of roadway surrounding rock and mining face stress during secondary mining face of 50305 working face are analyzed systematically，so as to use reasonable support measures. Through theoretical analysis，the mechanical fracture criterion of secondary mining roadway roof is studied，and the scope of the failure zone is determined in advance. Through the numerical simulation，the mining face stress during the working face mining is analyzed in detail，and the roadway stress and displacement are analyzed in detail，which provides a reference for the use of reasonable advance support measures during the secondary mining to ensure safe mining. Through the field analysis，the surface displacement and deformation of roadway and hydraulic support load during secondary mining are analyzed，and the field application effect and whether there are shortcomings are observed to provide reference for other mines. The secondary mining roadway is supported with constant resistance anchor cable，U-section steel and temporary support，and the secondary mining effect of self-formed roadway without coal pillar is good.
