本文利用有限元和离散元数值模拟及力学解析计算，研究了放顶煤采场中上覆岩层运动规律，提出了采场上覆岩层运动结构为拱──梁结构及影响综放支架载荷的顶板岩层范围，并分析了影响顶板运动的主要因素。
In this paper, the law of overlying strata movement in caving coal caving face is studied by means of finite element and discrete element numerical simulation and mechanical analysis and calculation. The motion of overlying strata in caving field is arched ─ ─ beam structure and the load affecting the fully mechanized caving support Roof strata range, and analyzed the main factors affecting the roof movement.
