By using UDEC program to simulate the roof stability in face area under different top coal in fully-mechanized mining with top coal caving, simulated model is founded, simulated projects are designed and mechanical parameters are set.

• 运用UDEC数值模拟程序,以不同顶煤条件下的综放开采端面顶板稳定性模拟为例,建立了数值模型、设计了计算方案、设定了力学参数;
