| 摘 要： | 为分析采动影响下黄河北煤田顶板破断过程，利用离散元数值模拟软件UDEC模拟黄河北煤田薄煤层采场顶板破断过程，得到薄煤层采场上覆岩层运动规律参数，即直接顶、基本顶初次来压步距和周期来压步距，结合相关理论进行对比分析，丰富和完善薄煤层采场上覆岩层运动规律，为采场顶板的控制设计提供依据。

| Abstract: | In order to analyze the roof breaking process of the Yellow River North Coal Field under the influence of mining,the discrete element numerical simulation software UDEC was used to simulate the roof breaking process of the thin coal seam stope in the Yellow River North Coal Field.The first step and the periodic step,combined with related theories to make a comparative analysis,enrich and improve the movement law of the overlying strata on the thin coal seam stope,and provide a basis for the control design of the stope roof. |

| Keywords: | thin seam rock pressure numerical simulation roof breaking movement law strata control |
