摘要
本文结合实际地质情况 ,运用有限元法对悬移支架放顶煤开采进行了数值模拟 ,并与模拟实验相比较 ,分析了采场应力应变的变化规律。
With the real geologic conditions, the hydraulic support sub level cave mining is analyzed through FEM simulation in this paper, and the principle of stress strain in working field is analyzed. The simulated results are compared with the result of simulating experiment, and analyzed results are according with the real practice.
