摘 要: 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。 The intention of this paper is to simulate the process of the mining advance by the technology of finite difference value simulation method based on the rule of overburden rock movement. In the process of mining advance, the overlying rock destruction and the movement rule and the variation process and rule of the support pressure and concentrating parameters change with mining advance are analyzed.
