摘　　要：为了研究支架初撑力对仰采综放工作面端面围岩的影响,确保工作面安全快速推进,采用UDEC2D数值模拟软件模拟了不同支架初撑力对仰采综放工作面围岩稳定性的影响。结果表明,支架的初撑力对控制工作面围岩的稳定有极其重要的作用,增加支架的初撑力可以有效控制顶板的运动,确保工作面端面围岩的稳定,并确定80113工作面液压支架的初撑力不应小于4 750 kN。To study the influence of support setting load on surrounding rock stability in upper-mining fully-mechanized caving face and ensure the working face advance rapidly, the influence of different support setting load on surrounding stability was simulated by numerical simulation software UDEC^2D in this paper. The result shows that the setting load plays an extremely important role on controlling the surrounding rock stability, and increasing the setting load can effectively control the movement of surrounding rock. In the end, the reasonable setting load of hydraulic supports was determined：it is not less than 4750 kN on 80113 working face.
