基于采场覆岩运动规律,运用有限差分数值仿真技术对典型采场工作面推进过程进行数值仿真分析。文章着重研究工作面推进过程中上覆岩层破坏和移动规律,以及支承压力和支承压力集中系数随工作推进的变化过程和变化规律。
Based on the law of overlying strata motion, the finite difference numerical simulation technique is applied to simulate the advancing process of working face of typical stope. The article focuses on the study of the law of overlying strata failure and movement in the process of advancing face and the variation process and variation of support pressure and supporting pressure concentration factor with work advancement.
