摘　　要：在大量工程实践的基础上,采用数值力学分析,详细地分析了工作面开采引起的围岩应力演化过程及特点,讨论了工作面开采影响巷道的围岩位移特点.并进一步分析了围岩应力和跨采巷道位移之间的关系以及对工程实践的指导作用.Based on a large number of engineering practice, surrounding rock stress evolving and features induced by mining was analyzed by numerical simulation. Surrounding rock displacement features induced by overhead mining was also discussed. The relation of surrounding rock stress and roadway displacement was obtained. It can proposed guide for engineering.
