| 摘 要： | 采用极限平衡法和FLAC3D数值模拟法对不同高度、坡面角、载荷情况下,以及岩石台阶下留不同宽度的煤柱等状态下,拉斗铲作业实体高台阶的安全稳定性进行了系统地研究.用赤平极射投影法确定黑岱沟露天煤矿拉斗铲作业实体高台阶的破坏形式为楔形体单面滑动和楔形体双面滑动.研究成果经现场实际应用证明,黑岱沟露天煤矿拉斗铲作业实体高台阶采用高38m、坡面角65°、留4m煤柱的参数是安全稳定和合理可行的. |
| 关 键 词： | 拉斗铲作业实体高台阶 楔形体 极限平衡法 安全系数 |

| Abstract: | FLAC3D numerical simulation and equilibrium limit methods were used to analyze the stability and safety of a high,solid bench used in dragline operations. The effects of changing bench height,slope angle and load were examined. The safety factor associated with different widths of the remaining coal-pillar was analyzed. The Heidaigou surface coal mine has high solid benches used with dragline operations. Destruction of these benches by single-or double-side sliding was examined by a stereographic projection... |
| Keywords: | FLAC3D high solid bench on which dragline works,wedge limit equilibrium method FLAC~(3D) safety factor |
