| 摘 要： | 确保采场上覆岩层稳定是矿井安全生产的关键。只有确定了采场上覆岩层的运动情况才能进行有效的采场支护设计。运用岩石破裂渐进过程分析(RFPA^2D)系统，对某矿采场工作面上覆岩层随工作面推进的运动情况作了数值模拟，从中有效地获取了上覆岩层的运动信息，确定了上覆岩层的运动范围，为有效控制采场顶板事故、合理进行采场支护设计提供了依据。

| Abstract: | It is a key for mine safe production to ensure the stability of overlying rock strata in stope. The effective support design of stope can be made out only if the moving scope of overlying strata is determined. The numerical simulation of whole moving process of overlying strata with the advance of stope face in a certain mine has been carried out by using Rock Failure Process Analysis system (RFPA~(2D)). Through the numerical simulation, the some valuable information about the movement of overlying strata has been obtained, and the moving scope of overlying strata has been determined. These provide the bases for controlling the roof failure and reasonably designing the support of stope. |
